Install a Python package into a different directory using pip?

Tags: python pip

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?


pip install --install-option="--prefix=$PREFIX_PATH" package_name

You might also want to use --ignore-installed to force all dependencies to be reinstalled using this new prefix. You can use --install-option to multiple times to add any of the options you can use with python install (--prefix is probably what you want, but there are a bunch more options you could use).

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.

Upgrade pip if needed

On Linux or OS X:

pip install -U pip

On Windows (this works around an issue):

python -m pip install -U pip

Installing a Python package often only includes some pure Python files. If the package includes data, scripts and or executables, these are installed in different directories from the pure Python files.

Assuming your package has no data/scripts/executables, and that you want your Python files to go into /python/packages/package_name (and not some subdirectory a few levels below /python/packages as when using --prefix), you can use the one time command:

pip install --install-option="--install-purelib=/python/packages" package_name

If you want all (or most) of your packages to go there, you can edit your ~/.pip/pip.conf to include:


That way you can't forget about having to specify it again and again.

Any excecutables/data/scripts included in the package will still go to their default places unless you specify addition install options (--prefix/--install-data/--install-scripts, etc., for details look at the custom installation options).
