Installing collected packages: pkginfo, twine
Found existing installation: pkginfo 1.3.2
Cannot uninstall 'pkginfo'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

pip install twine --ignore-installed
