I was trying to install a library using flit. The correct command is flit install. Flit is a simple way to package and publish Python packages on PyPI. You can read up about it in the docs. They also have a “Why use Flit” section. Typo of the day: `flirt install` ๐คญ — Mariatta ๐คฆ (@mariatta) July 15, 2018
