How to use pip with multiple instances of python

Question

I recently installed python3 only to realize that mysql-python as well as many other modules were not well supported with it yet. So I changed the path in my bashrc file to point to an installation of python 2.7. The problem is that when I installed python 3 I also installed distribute and pip along with it. I removed the pip and distribute files from the python3 bin directory and installed setuptools and pip using python 2.7 however now when I use the pip command to install django and mysql-python, I get a bash error python331/bin/pip No such file or directory. It's still looking for pip in the python3 install. How can I remedy this?

Thanks

You should have used virtualenv.

...I get a bash error python331/bin/pip No such file or directory. It's still looking for pip in the python3 install. How can I remedy this?

bash, by default, hashes the locations of commands to avoid searching $PATH each time, so if, when you execute...

$ type pip

...you get something like...

pip is hashed (python331/bin/pip)

...you just need to clear the hash table for bash with...

$ hash -r

...then it'll pick up the version in Python 2.7 the next time you try to run pip.

Fixed it.

Renamed the directory of where the python3 was installed, bash automatically looks for the next available python install python 2.7
