木星笔记本无法启动 - 未找到符号错误

Question

A while back, I upgraded my python version via brew to 3.9.0 and now, whenever I try to start Jupiter notebook, I get this error:

Traceback (most recent call last):
  File "/Users/me/Library/Python/3.9/bin/jupyter-notebook", line 5, in <module>

I've tried completely uninstalling and reinstalling jupiter to no avail. I've also tried reinstalling the zmq module that seems to be a part of this error chain. My thought is that there must be some component that's avoiding my uninstalls that needs to be fixed/updated, but I'm not sure what it could be.

I'm also running MacOS 10.13.6. I notice it states that one of these modules was built for Mac OS X 10.15. Could this instead be the issue?

Answer 1

The answer provided in this link worked for me: Cannot run jupyter everywhere (terminal, anaconda distributer) Mac os 10.12.6

"downgraded pyzmq to 20.0.0 and it worked fine. pip install pyzmq==20.0.0

I believe the issue is in pyzmq's cython packaging - and should be raised as a bug to them."

The bug has been raised and is expected to be fixed by release 21.0.2
