pip install local package to target directory
问题 I have a Python library that is published to PyPI. Before pushing each new version of the library, I want to test it by upgrading a sample application to use the new version. The suggested method to do this is to work in "development mode" using the -e ( --editable ) flag: $ pip install -e <my package root> And this does indeed install the package into my global environment. However, my sample program is written for Google App Engine, which requires that all third-party libraries be copied
