DistutilsOptionError: must supply either home or prefix/exec-prefix -- not both
I've been usually installed python packages through pip.
For Google App Engine, I need to install packages to another target directory.
pip install -I flask-restful --target ./lib
but it fails with:
must supply either home or prefix/exec-prefix -- not both
How can I get this to work?
Are you using OS X and Homebrew? The Homebrew python page https://github.com/Homebrew/brew/blob/master/docs/Homebrew-and-Python.md calls out a known issue with pip and a work around.
Worked for me.
You can make this "empty prefix" the default by adding a ~/.pydistutils.cfg file with the following contents:
> [install] > prefix= >
Edit: Do not use this Homebrew recommended option, it will break normal pip operations.
