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 have a Rocky 9 host with multiple versions of Ruby installed using rbenv. # rbenv versions * system (set by /usr/local/rbenv/version) 2.4.1 2.7.1 2.7.6 The *system version of Ruby is 3.0.7p220. As part of my deployment of a Ruby (2.4.1) on Rails app, I can see the following errors when attempting to build and install nokogiri defined in a Gemfile: checking if the C compiler accepts ... no Building nokogiri using system libraries. pkg-config could not be used to find libxml-2.0 Please install either pkg-config or the pkg-config gem per gem install pkg-config -v "~> 1.1.7" pkg-config could not be used to find libxslt Please install either pkg-config or the pkg-config gem per gem install pkg-config -v "~> 1.1.7" pkg-config could not be used to find libexslt Please install either pkg-config or the pkg-config gem per gem install pkg-config -v "~> 1.1.7" ERROR: cannot discover where libxml2 is located on your system. please make sure pkg-config is installed. *** extconf.rb failed *** However, if I run the following, I can see the first 3 libraries are installed. # pkg-config --exists libxml-2.0 && echo "Package exists" || echo "Package not found" Package exists # pkg-config --exists libxslt && echo "Package exists" || echo "Package not found" Package exists # pkg-config --exists libexslt && echo "Package exists" || echo "Package not found" Package exists pkg-config does seem to find libxml2: # pkg-config --exists libxml2 && echo "Package exists" || echo "Package not found" Package not found The packages already installed are: # rpm -qa libxml2-devel libxslt-devel libxml2 libxml2-2.9.13-6.el9_5.2.x86_64 libxml2-devel-2.9.13-6.el9_5.2.x86_64 libxslt-devel-1.1.34-9.el9_5.1.x86_64 Any idea what I am missing?

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.

I am trying to remove all ruby gems before uninstalling ruby. The command I am using is: sudo gem uninstall --all to achieve this. However, I have to type y continually to remove things. Is there a way I could achieve the same thing without having to type y to remove all of the dependencies?

I've also tried executing command from error message (gem install mysql2 -v '0.3.17') but of course this also failed with same result. What can be the source of those errors? I am rather new to linux environment so I let automats do everything for me and I'm following guides (this one in this case ) Can there be a problem with mysql that is already installed by apt-get along with apache? P.S. It is raspbian/debian distro.

I have built a node.js app that listens for webhooks. Currently it is used to build a jekyll website. I have configured it on my server and jekyll build works perfectly when I run it in the root of my jekyll website (which is sending the hooks). When I run the node.js app over ssh in a shell everything works fine as well when a git hook is triggered. However, when the node.js app is run from an upstart script (shown below) it doesn't seem to find the gems. It keeps asking for dependencies which I am sure I have installed (globally as well as for my user). Inside the script I have put `echowhich jekyll and this shows that it is indeed pointing to the locally installed jekyll bin: /home/christophe/.gem/ruby/2.0.0/bin/jekyll`.

In the meanwhile I have solved it by intalling a list of deps manually as root. However, I don't think this is a good approach as the upstart is explicitly running as my user. And secondly, this software needs to run on a server I don't have root permissions on.

So this is a bit weird. Gem works fine. When I go to gem install bundler, the system outputs the following: Successfully installed bundler-1.16.2 1 gem installed When I check to see what gems are installed with gem list the bundler shows up: *** LOCAL GEMS *** bigdecimal (1.2.0) bundler (1.16.2) io-console (0.4.2) json (1.7.7) psych (2.0.0) rdoc (4.0.0) and yet when I go to run bundle install, I get the following: bash: bundle: command not found I have tried restarting the system, I have used yum erase gem and then reinstalled it, and I have tried gem install bundler again when it didn't work and I am still getting the same error. I am on CentOS 7.5 Thanks in advance for the help.

I'm trying to install Jekyll on my Linode server running openSUSE Leap 42.3, but Zypper gives me this error: # zypper install ruby2.1-rubygem-jekyll Loading repository data... Reading installed packages... Resolving package dependencies... Problem: nothing provides rubygem(ruby:2.1.0:colorator:0) >= 0.1 needed by ruby2.1-rubygem-jekyll-3.1.6-3.3.x86_64 Solution 1: do not install ruby2.1-rubygem-jekyll-3.1.6-3.3.x86_64 Solution 2: break ruby2.1-rubygem-jekyll-3.1.6-3.3.x86_64 by ignoring some of its dependencies Choose from above solutions by number or cancel [1/2/c] (c): If I force-install by selecting solution 2, Jekyll fails because it cannot find the correct version of the colorator gem. This occurs even if I install the ruby2.1-rubygem-colorator package. Is this an issue with the Jekyll package, or is the problem upstream? I don't want to use the gem command directly because this could result in conflicts with files installed by the package manager. I'd rather use one and only one way to install applications at the system level.

I'm using Debian Linux, Ruby on Rails 5 on Apache with Passenger. I crated the file ~/.gemrc gem: --no-rdoc --no-ri However, I'm running the command sudo bundle install and it doesn't seem to be picking up the above. How do I get "sudo" to recognize my "~/.gemrc" file? ps - I have to run with sudo b/c the Apache directory from where I'm running this command complains about bad permissions if I don't do this.

I'm new to nix package manager. After installing nix into Ubuntu 16.04 LTS(Japanese translated version), I installed ruby with nix-env command. Then I did gem install bundler. That seemed to work fine. However I couldn't use bundle command, while require 'bundler' in IRB session seemed to work fine. That made me confused. From my understanding, in general, it is no need to do anything for using bundle command after gem install bundler How should I understand this problem and how can I solve it? P.S English is not my native language; please excuse typing, grammar or/and word selecting errors. $ nix-env -q nix-1.11.9 ruby-2.4.1 $ gem install bundler Fetching: bundler-1.15.0.gem (100%) Successfully installed bundler-1.15.0 Parsing documentation for bundler-1.15.0 Installing ri documentation for bundler-1.15.0 Done installing documentation for bundler after 6 seconds 1 gem installed $ bundle init プログラム 'bundle' はまだインストールされていません。 次のように入力することでインストールできます: sudo apt install ruby-bundler $ irb require 'bundler' => true

(Gem::FilePermissionError) You don't have write permissions into the /var/lib/gems/1.8 directory. So I think I have to use sudo. But I still get the original error, $ sudo gem install pdfbeads ERROR: Error installing pdfbeads: nokogiri requires Ruby version >= 1.9.2. I think it is because under sudo, the user is root, which still has the older version ruby1.8.7 as the default. So I wonder what can I do now?
