error: Could not find suitable distribution for Requirement.parse('pynacl>=1.0.1')

/usr/bin/ld: cannot find XYZ also appears when linking with -static and there is no libXYZ.a. Development packages typically contain the .a versions, although some distros seem to think static libraries are antiquated enough to drop support completely. You may have to build the library from source.

If this is a Debian or Ubuntu machine,

sudo apt install libffi-dev

and then try again.

For other distributions, the installation method and package name may be different.
