Does PIP/Python support multiple versions of the same package?
问题 Let's say I have a package foo , and foo packages up binary shared objects that I use in multiple Python scripts. Foo v1 (shared objects) Bar v1 (requires Foo v1) Baz v1 (requires Foo v1) Now I want to push out a new breaking update to Foo. Foo v2 (shared objects) Bar v2 (requires Foo v2) Foo v1 (shared objects) Bar v1 (requires Foo v1) Baz v1 (requires Foo v1) Can old-dependencies with different major versions in semvar be distributed over PyPI? If so, how? 回答1: Pypi can and will track
