I am unable to install pyzmq:

is this a quick fix or Is this never going to work because the package will need C libraries?

Looking at Languages on the right side of https://github.com/zeromq/pyzmq it appears that there is C, C++, and Cython code in that repository. Given Apple's iOS security rules, this might be a blocker. You might open an issue there to see if any Pythonista users in that community can help you.

Thanks Christian! There are some other similar issues in the queue here and it looks like the official answer is ' if it needs C libraries, it isn't (and won't be) supported' by pythonista. But I will reach out to someone at pyzmq. Thanks again :)

If your goal is to run 0mq, then you are out of luck. If libzmq is not already installed as part of pythonista, or along with iOS, then it will not be runnable without jailbreak.

If your goal is to simply be able to have autocomplete for developing on iOS for execution elsewhere, then there may be ways to install pyzmq, but basically just as a non functioning wrapper.
