無法運行 jupyter-lab/jupyter-notebook

Question

經過多次重新安裝 anaconda 和 jupyter-notebook 的迭代后，我遇到了同樣的錯誤

    Traceback (most recent call last):

重新安裝 pyzmq -

pip install pyzmq

此外，嘗試使用輪文件安裝 pyzmq，也沒有奏效。 似乎是什么問題？

Answer 1

我希望您的問題與此類似。

解決方案要么是降級到pyzmq版本 21：

pip install pyzmq==21.0.0

或者安裝VS C++ Redistributable庫（與第 21 版相比，這是第 22 版的更改）。
