I don't know Mac well enough to help you fix that but the error indicates that you need to install a package containing crypt.h header file.

As I'm looking for some solutions online, it might also require some changes here in the code because the functions might be declared in different header files.

See the README:

This library is tested with the crypt_r implementation in Fedora Linux (libxcrypt, as of 2024), and should work with compatible implementations of crypt_r (such as libcrypt.so from older glibc).

Do you have libxcrypt (or another implementation) installed on the system?

[hroncok]

For example, libxcrypt is available on homebrew.

libxcrypt 4.4.36 is already installed and up-to-date
but
ERROR: Could not build wheels for crypt-r, which is required to install pyproject.toml-based projects

[hroncok]

libxcrypt 4.4.36 is already installed and up-to-date

Installed how? Including the devel files (such as the header)?

[hroncok]

@sergei4e Do you still have this problem? Do you have libxcrypt header files installed?
