更新 spyder3 后，我无法连接到内核

我无法连接到 spyder 上的内核，并且在更新 spider3 后收到“启动内核时发生错误”的提示。顺便说一句，我不使用 Anaconda 或其他东西。我的操作系统是 ubuntu 18.04。帮帮我 :)

启动内核时发生错误错误是：

Traceback (most recent call last):

答案1

这里的问题是关于权限的。

因此，为了解决这个问题，我使用 更改了该目录的所有权sudo chown systemname /path。

注意，这里不是系统名称， 这将是卡恩并且路径将是 /home/kaan/.local/share/jupyter/runtime/。
