在Spyder的IPython控制台中启动内核时发生错误

Question

当我启动spyder时，出现此错误：

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'

我完全没有编程经验，但是我尝试在Anaconda提示符下输入命令，但是这些都不起作用（"conda update jupyter_client"和"conda update --all"）我也尝试安装和卸载，但仍然出现相同的错误。

这似乎是权限问题。以管理员身份运行Spyder（右键单击它->以管理员身份运行）可以解决此问题。

更新：按照@CarlosCordoba：“要解决此问题，OP需要在Anaconda提示符中运行conda update anaconda，然后运行conda update jupyter_client”

请注意，原始解决方法在这种情况下也可以正常工作。
