Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-h5k4L0/pynacl/

See above for errors when installing ParallelSSH, and I am not sure how to resolve these errors.

Many Thanks George Durant

Hi there,

Thanks for the interest and report. The above error is from installing pynacl, a dependency of paramiko. It is not an error from parallel-ssh.

Refer to pynacl installation instructions. It seems to be missing a libffi system library dependency.
