For at least a week now i have been trying to install Bettercap on my Raspberry PI using gem but whenever i type in: sudo gem install bettercap i receive an error message that says ERROR: While executing gem ... (Gem::Exception) Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources Every fix that has been suggested to other people yields no results: **Option 1: "http option"** According to the answer by Filippo De Bortoli in this thread on the same issue, disabling the https protocol will solve it. However after running these commands: gem source -r https://rubygems.org/ gem source -a http://rubygems.org/ I still get this error: ERROR: While executing gem ... (Gem::Exception) Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources **Option 2: rebuild** As suggested by Filippo De Bortoli in the same thread he reinstalled ruby after installing OpenSSL, however my raspbian came with OpenSSL and running sudo apt-get install openssl only confirms i have the latest version. I have also re-built ruby 3 times since i started getting this. **Option 3: install locally** After finding out that you could install the gems locally i installed the source and ran. sudo gem install --local bettercap-1.6.2b.gem and got the output: ERROR: Could not find a valid gem 'em-proxy' (>= 0.1.8, ~> 0.1) in any repository I am guessing since it is only searching the local disk it can not find the dependencies it needs, so i decided to locally install "em-proxy" only to find it needed dependencies, which also needed dependencies. Great. So i decided to leave it for the sake of my sanity and it was overall impractical. ---------- To wrap up, **how do i get rid of this error or at the very least bypass it?** Just in case you wanted to know here is the output of gem -v: 2.4.5 and the output of ruby -v: ruby 2.2.2p95 (2015-04-13 revision 50295) [armv6l-linux-eabihf]

I am using gem 3.5.23 and `ruby 3.3.5 (2024-09-03 revision ef084cc8f4) [x86_64-linux] ` Thank you for help

I was reading [the documentation](https://www.jetbrains.com/help/ruby/2021.1/set-up-a-ruby-development-environment.html#prerequisite_dependencies) . In Debian based Linux, I have to install build-essential, libssl-dev. But, what about Arch-Based Linux? I had tried

sudo pacman -Syy build-essential libssl-dev

But, unfortunately those packages aren't available. I had tried with yay command also. But, I couldn't install them using yay also. I had installed base-devel also. I was reading [the question](https://bbs.archlinux.org/viewtopic.php?id=122984) also. But, don't need them. PHP works by Lampp/Xampp. But, Ruby needs build-essential && libssl-dev. While they aren't available in Manjaro than, how Ruby programmer works in Manjaro? So, there must be similar package like this. - I am using Rubymine - Ruby version : ruby 3.0.1p64 (2021-04-05 revision 0fb782ee38) [x86_64-linux] - gem version : 3.2.15 I had installed openssl while Google is saying build-essential is base-devel and, libssl-dev is openssl.

sudo pacman -Sy openssl

Then, I had run following commands

gem install rails
ruby -v
gem -v 
rake -v
bundle install

- Bundler version : Bundler version 2.2.15 But, when I installed bundler using the command gem install bundler I got following error >WARNING: You don't have /home/istiak/.local/share/gem/ruby/3.0.0/bin in your PATH,
gem executables will not run.
Successfully installed bundler-2.2.17
1 gem installed When I check rails version I get there's no rails package. And, I had installed rails successfully. I am adding error in short below : 1. I don't have rails after installation also 2. No Gemfile found error while compiling ruby file from Rubymine 3. Could not locate Gemfile while executing bundle install

EDIT: I'm very sorry, that I initially didn't make my requirements clear. I don't actually have access to the string written in a backslash-escaped way and have amended the example to make that clearer. The two answers that I got as of now require me to have backslashes in the string to begin with, which is not the case. I have a string that may contain lots of difficult characters, which I want to write to a file in an escaped way, so that it would generate the same string if given in double-quotes to echo -e, perl, etc. I tried using shell-quote and perl's quotemeta function, but they do different quoting. Example:

# I have a file containing difficult characters:
$ cat text
line0'field0
line1	field1"
$ cat -v text
line0'field0
line1	field1"

Expected raw output including the enclosing double-quotes:

"line0'field0\nline1\tfield1\""

I'm sure there must already be a built-in solution to this.

I'm trying to record the size of the compressed build file using Fastlane in my CICD pipeline. If I try this in the command line: du -h fileName.ipa | awk '{print $1}' it works fine. However, if I try to put it in my script, like so: sh ''' # Add filesize to release message var fileName=cat '"#{IPA_FILE_NAME_FILE}"' fileSizeInfo=(du -h '"#{IPA_FILE_PATH}"'$fileName | awk '{print $1}') echo "$buildInfo" sed -i -e "s|FILESIZE_INFO|'"$fileSizeInfo"'|g" '"#{RELEASE_MESSAGE_HTML_FILE_NAME}"' ''' it gives me these syntax errors: [!] Syntax error in your Fastfile on line 263: Fastfile:263: syntax error, unexpected '{', expecting `end' ..._FILE_PATH}"'$fileName | awk '{print $1}') ... ^ Fastfile:285: syntax error, unexpected `end', expecting end-of-input end ^~~ I'm kind of a newbie to shell scripting, so any help is appreciated - I probably just have some quotes in the wrong place or something. If it helps, Fastlane uses Ruby syntax, so that's Ruby string interpolation in there. Edit: Here's the whole lane I'm calling in my fastfile, for more context: # Send message MS Teams Channel lane:sendTeamsMessage do |options| =begin MS Teams messages are sent using webhooks and it got limited support to HTML and Markdown. This implementation uses HTML formatted message. Webhook will not accept new lines or double quotes because it can break the JSON struture. The message file preparation is done in multiple steps. 1.

With Vagrant, I aim to have three master and two node machines on my Ubuntu host. My Vagrantfile:

Vagrant.configure("2") do |config|
  config.ssh.insert_key = false
  (1..3).each do |i|
    config.vm.define "master" do |master|
      master.vm.box = "ubuntu/bionic64"
    end
  end
  (1..2).each do |i|
    config.vm.define "node" do |node|
      node.vm.box = "ubuntu/bionic64"
    end
  end
  config.vm.network "public_network"
  config.vm.provider "virtualbox" do |vb|
    vb.memory = "3072"
    vb.cpus = "3"
  end
end

I have after vagrant up:

$ vagrant status
Current machine states:

master                    running (virtualbox)
node                      running (virtualbox)

Why did the loop fail?

Help! Trying to install Cocoapods on my mac, kept getting an error, thought it might be something to do with having a really old version of Ruby. Then this happened:

How should I convert cs_primitive section into yaml file? cs_primitive { 'nfsshare_fs': primitive_class => 'ocf', primitive_type => 'Filesystem', provided_by => 'heartbeat', parameters => { 'device' => '/dev/disk/lvname', 'directory' => '/share', 'fstype' => 'ext4' }, }-> I tried the below code but it didn't work. corosync::cs_primitive: 'nfsshare_fs': primitive_class: 'ocf' primitive_type: 'Filesystem' provided_by: 'heartbeat' parameters: device: '/dev/disk/by-id/lvname' directory: '/share' fstype: 'ext4' Thanks.

I've been trying to update Git for a while. I'm currently stuck on 1.7.3.4, and I've tried updating to 1.7.4.x, and 1.7.5.x but it never works. Today I compiled and installed Ruby 1.9.2, but it still shows up as 1.8.7. I'm running 10.6.7 on a MacBook Pro. I have no idea why it won't update. Any ideas? :(

I have been practising setting up a production environment with puppet, and now I'm setting up everything to accommodate HTTP requests with Apache. Since Puppet runs on Ruby, I also need Passenger to get it running, but I can't install it because I keep getting an error saying that I need a fresher version of Ruby installed. At first this was an actual issue because I'm using a core version of CentOS 6.5 that only comes with Ruby 1.8. I then updated the yum repos, the system itself and did wget to download the current version, configured and installed which gets me to where I stand right now. I installed Gems and tried to get Passenger again but I am faced with the same wall, version problems. Here you can see the installed version of ruby and the issue. [vagrant@puppetmaster ~]$ sudo gem install rack passenger ERROR: Error installing rack: rack requires Ruby version >= 2.2.2. ERROR: Error installing passenger: rake requires Ruby version >= 1.9.3. [vagrant@puppetmaster ~]$ ruby --version ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]

A colleague wrote a filter utility for me in ruby that allows me to print barcodes from a textfile. (The filter replaces @{blah} with the proper PCL and a barcode checksum character so that "blah" prints in a barcode font.) I call this filter from an executable in my local bin directory. However on a fresh reboot, this process fails. (I can switch between 2 particular failures by manipulating permissions; either the filter fails to replace @{blah} with anything, or nothing prints.) If I stop and restart cups, it all works like I want it to. How can I make this work without having to restart CUPS?

I have a background job written in Ruby that connects to several SFTP servers, download some files and finally, move the downloaded files to another folder in the sftp server. The issue is that the rename command fails when in just one server. What is interesting about this issue is that **if I connect to the server using ubuntu's sftp library or using Ruby's interactive console and run the same code used by the background job, it doesn't fail.** So, it is not a permission issue. --- **2nd approach:** I updated the implementation with the following workaround hoping that the remove method will work:

def move(from_path, to_path)
    sftp.rename(from_path, to_path) do |response|
      sftp.remove(from_path) unless response.ok?
    end
  end

The code above works for about 75% of the file by deleting them. Any ideas of what could be the issue here? Libraries used here are: https://github.com/net-ssh/net-sftp https://github.com/resque/resque

It was working just fine a couple of months ago, but now it just returns the following, any ideas why libldap-2.4.so.2 could not be found all of the sudden? OS: Manjaro 21.2.1

I am trying to install sensu-client on Ubuntu 16.04 node and after installation I am unable to start the service. Below is the error I am getting while trying to start the service.

Is there a way I can make them work with current os version?

I was trying to install specific version Ruby in Manjaro. I had tried some query.

sudo pacman -Sy ruby:2.6.6
sudo pacman -Sy ruby-2.6.6

Both of them returning target not found. I was reading [the thread](https://bbs.archlinux.org/viewtopic.php?id=245606) . But, Some people said that pacman doesn't allow to install specific version. How can I install specific version of Ruby then? Current Ruby version is 3.0.1. But, I need 2.6.6. So, I must have to install that version of Ruby. I had installed 2.6.6 following way.

sudo rvm install 2.6.6

When I tried to use it

sudo rvm use 2.6.6
sudo rvm use 2.6.6 --default

I got following error >RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too, you can ignore these warnings with 'rvm rvmrc warning ignore /home/istiak/qpixel/Gemfile'. To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.

You need to change your terminal emulator preferences to allow login shell. Sometimes it is required to use /bin/bash --login as the command. Please visit https://rvm.io/integration/gnome-terminal/ for an example.

I'm trying to install a modern Ruby on Amazon Linux which I think is RHEL based. I ran sudo yum install rh-ruby26 which is a legit package, and it installed some files. However when I try and run ruby, there's no executable found. I tried rpm -ql rh-ruby26 but it says "contains no files". Am I missing something ? Where did yum install my binary to run ruby ?
