          If you are seeing a compilation error please try the following steps to
          successfully install bcrypt:
          1) Upgrade to the latest pip and try again. This will fix errors for most
             users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
          2) Ensure you have a recent Rust toolchain installed. bcrypt requires
             rustc >= 1.64.0. (1.63 may be used by setting the BCRYPT_ALLOW_RUST_163
             environment variable)

Answer 1

The problem comes with bcrypt 4.0.0

You can fixing with downgrade bcrypt to 3.2.2 (the latest version before 4.0.0) fixed this for me.

$ pip install bcrypt~=3.2.2
$ pip3 install bcrypt~=3.2.2

It worked for me.
