Adding directory to PATH -- Ubuntu

I realize that there are several similar questions out there and I'm unsure if I'm simply misunderstanding the solutions. I only recently began using Ubuntu, so I'm still familiarizing myself with everything. I'm trying to set up the Django web-development framework and when I install it via the terminal, I receive this message: > "WARNING: The script django-admin is installed in '/home/bp102412/.local/bin' which is not on PATH. Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location." The following is what I've tried so far:

=$PATH:home/bp102412/.local/bin

in .bash_profile and

if [ -d "new_dir" ] ; then
  PYTHONPATH="$PYTHONPATH:new_dir"
fi
EXPORT $PYTHONPATH

But, I was also reading that you shouldn't use

on bash_profile. I've restarted the shell after each change to the file and received the message each time, so I'd appreciate it if someone could point out what I'm doing wrong. Note: I found that if I source ~/.bash_profile that it solves the problem, but I don't want to source it each time I plan to use this package in the terminal, I'd like it to be included in the PATH each time the terminal starts.
