I know the obvious answer is to use virtualenv and virtualenvwrapper, but for various reasons I can’t/don’t want to do that.
So how do I modify the command
pip install package_name
to make pip install the package somewhere other than the default site-packages?
The –target switch is the thing you’re looking for:
pip install --target=d:\somewhere\other\than\the\default package_name
But you still need to add d:\somewhere\other\than\the\default to PYTHONPATH to actually use them from that location.
-t, –target <dir>
Install packages into <dir>. By default this will not replace existing files/folders in <dir>.
Use –upgrade to replace existing packages in <dir> with new versions.
Upgrade pip if target switch is not available:
On Linux or OS X:
pip install -U pip
On Windows (this works around an issue):
python -m pip install -U pip
