Install fails with ImportError: libffi.so.8

[pwrightkcl]

I cannot pip3 install names using my installation of Python in ~/.local. This is on a shared server where I do not have sudo rights.

Traceback:

    ERROR: Command errored out with exit status 1:

    ----------------------------------------

I'm not sure if this is specific to names or not, so feel free to close the issue, preferably redirecting me. It looks like libffi is in my .local directory, but pip isn't finding it.

$ ls -l ~/.local/lib/*libffi*
-rw-r--r-- 1 ... libffi.a
-rwxr-xr-x 1 ... libffi.la
lrwxrwxrwx 1 ...libffi.so -> libffi.so.8.1.0
lrwxrwxrwx 1 ... libffi.so.8 -> libffi.so.8.1.0
-rwxr-xr-x 1 ... libffi.so.8.1.0
