TomlError when installing 4.2.0

[madnutter56]

Starting with 4.2.0 I am getting an error installing bcrypt, looks related to toml parsing?

Collecting bcrypt>=3.1.3 (from paramiko==2.7.1)
  Downloading bcrypt-4.2.0.tar.gz

You're using a quite old version of pip, are you able to reproduce this after upgrading your version of pip?
