output

The command python -m pip install -U pip or pip install --upgrade pip might fail on Windows due to very long paths (see Upgrading pip fails on Windows when install path is too long). If that happens, assuming the module pymyinstall was installed with pip, we can now remove pip and use get_pip.py instead. This part requires pyquickhelper.

We try the url bootstrap.pypa.io/get-pip.py first then a local copy.
