启动ipython内核发生错误,在Spyder的IPython控制台中启动内核时出现PermissionError

Posted 2022-07-14 真·空

When I launch spyder, this error appears :

Traceback (most recent call last):

File "C:\\ProgramData\\Anaconda3\\lib\\site‑packages\\spyder\\plugins\\ipythonconsole.py", line 1572, in create_kernel_manager_and_kernel_client

PermissionError: [Errno 13] Permission denied: 'C:\\\\Users\\\\Sébastien\\\\AppData\\\\Roaming\\\\jupyter\\\\runtime\\\\kernel‑e1f2b044843b.json'

I am not experienced at all in programming but I tried to enter commands in the Anaconda prompt but none of this worked ("conda update jupyter_client" and "conda update --all")

I also tried to install and uninstall but I still get the same error.

解决方案

This seems a permissions issue. Running Spyder as administrator (right click on it-> run as administrator) solves the problem.

UPDATE:

As per @CarlosCordoba: "To fix this the OP needs to run conda update anaconda and then conda update jupyter_client in the Anaconda Prompt"

Note that the original workaround worked as well in this case.
