在 Spyder 的 IPython 控制台中启动内核时出现 PermissionError

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
kernel_manager.start_kernel(stderr=stderr_handle)

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

我在编程方面一点经验都没有，但我尝试在 Anaconda 提示符下输入命令，但是 none 这行得通（"conda update jupyter_client" 和 "conda update --all"）我也尝试安装和卸载，但我仍然得到同样的错误。

Answer 1

这似乎是一个权限问题。运行Spyder as administrator（右击->运行as administrator）解决问题

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

请注意，原来的解决方法在这种情况下同样有效。

Answer 2

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
spyder

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