【问题描述】：

Jupyter Notebook 正在运行，我可以打开一个 python3 笔记本。但我收到这个内核错误。这似乎是一个权限问题。但我不确定从哪里开始寻找。任何提示如何进行？

【问题讨论】：

你有进步吗？我试图用 spyder 重新安装 miniconda，当启动它时，我在控制台中得到几乎相同的错误（但没有提到龙卷风的行）。
浏览了一圈后，我找到了一个适合我的解决方案：将 jupyter_client 降级到 5.3.1（而不是当前版本 5.3.4）。 stackoverflow.com/questions/58075788/…
嗨，很抱歉我的回复晚了。还没有解决办法。但我会试试你的方法。谢谢！

【解决方案1】：

对我有帮助的是允许不安全的写入：

yourPythonPath\scripts\activate.bat
set JUPYTER_ALLOW_INSECURE_WRITES=1
jupyter-notebook

或者，您也可以在全局 Windows 环境变量中将 JUPYTER_ALLOW_INSECURE_WRITES 设置为 1。
