Choosing PIP Medical Coverage
If --exists-action is not defined, pip will prompt when decision is needed. So the most recent backup will be the one with the largest number after.
Presently, the only supported build system is setuptools, but future developments to the Python packaging infrastructure are expected to include support for other build systems. As well as package building, the build system is also invoked to install packages direct from source. The interface to the build system is via the setup.

However, not all packages use setuptools in their build scripts. The injection should be transparent to distutils-based projects, but 3rd pip options build tools wishing to provide a setup.
It can install packages, list installed packages, upgrade packages, and uninstall packages. Recent versions of virtualenv 1. If you are using a pre Just replace all occurrences of the latter with the former.
