If you are using `pip` to install packages (it comes by default with Python), you should **upgrade** it to the latest version.

Many exotic errors while installing a package are solved by just upgrading `pip` first.

/// tip

You would normally do this **once**, right after you create the virtual environment.

  a coordinated offline strategy. In addition, efforts to unite these failing
