export vars for python setup.py install --prefix

问题

When I install a python package with prefix

python setup.py install --prefix=$HOME/opt

In ~/.bashrc, I modify the PATH environment var.

export PATH=$HOME/opt:$PATH

Are there any other environment variables that I need to modify?

回答1:

You may need to modify PYTHONPATH.

回答2:

Use virtualenv for this. Virtualenv creates a directory which acts as a "little unix". You can activate and deactivate this environment as you like, and keep multiple environments for different purposes. Activating the environment will take care of all the environment variables.

virtualenv mynix
source mynix/bin/activate
cd packages/foo
python setup.py install
