A "distutils.cfg" has been written to:
|
|
#{distutils}
|
|
specifing the install-scripts folder as:
|
|
#{scripts_folder}
|
|
|
|
If you install Python packages via "pypy setup.py install", easy_install_pypy,
|
|
pip_pypy, any provided scripts will go into the install-scripts folder above,
|
|
so you may want to add it to your PATH *after* the `$(brew --prefix)/bin`
|
|
so you don't overwrite tools from CPython.
|
|
|
|
Setuptools has been installed, so easy_install is available.
|
|
To update setuptools itself outside of Homebrew:
|
|
#{scripts_folder}/easy_install pip
|
|
#{scripts_folder}/pip install --upgrade setuptools
|
|
|
