It sounds like the underlying system library is missing. Assuming your server runs Ubuntu, try running sudo apt-get install libsodium23 on the server in question :)

[ibohonos]

Server in Ubuntu, but this library is installed.

Unfortunately I am unable to reproduce this issue with the following Dockerfile

FROM ubuntu:18.10

RUN apt-get update -qy && apt-get upgrade -qy
RUN apt-get install -qy python3 python3-pip
RUN pip3 install pusher

And then running

python3 -c "import pusher"

It looks like the error is due to a failing internal import in the PyNaCl library. This seems odd. I would try reinstalling the library to see if that helps.

I'll close this issue as I am unable to reproduce it, so I cannot be of much help. If you are able to send a reproducible example, then feel free to re-open the issue.

pip uninstall and re-install pynacl, solved the problem.
