jupyter 控制台 "RuntimeWarning: coroutine 'ZMQSocketChannel.msg_ready' was never awaited"

Question

通过运行 jupyter-console 任意按 Enter 按钮显示此错误：

In [1]: /home/player1/.pyenv/versions/3.7.9/lib/python3.7/site-packages/jupyter_console/ptshell.py:852: RuntimeWarning: coroutine 'ZMQSocketChannel.msg_ready' was never awaited

我已经尝试过不同的 Linux 发行版的不同计算机（Ubuntu，Mint，Manjaro KDE，Manjaro XFCE）。我尝试了不同的 python 版本（>3.6），不同的 ipython 版本甚至 Docker.

有趣的是，jupyter-qtconsole、jupyter-notebook 和 ipython 工作正常。

我搜索的所有答案都是关于 ipython 或 jupyter-notebook，但我需要 jupyter -控制台.

Answer 1

pip install jupyter-client==6.1.12
