启动内核时出现 Spyder 权限错误，管理员权限不会更改任何内容

Question

当我启动 Spyder 时，我收到一条错误消息，提示权限被拒绝。这是 Spyder 中的输出：

An error ocurred while starting the kernel
The error is:

Traceback (most recent call last):
File "C:\Users\John\anaconda3\lib\site‑packages\spyder\plugins\ipythonconsole\plugin.py", line 1223, in create_kernel_manager_and_kernel_client
kernel_manager.start_kernel(stderr=stderr_handle)
File "C:\Users\John\anaconda3\lib\site‑packages\jupyter_client\manager.py", line 313, in start_kernel
self.kernel = self._launch_kernel(kernel_cmd, **kw)
File "C:\Users\John\anaconda3\lib\site‑packages\jupyter_client\manager.py", line 220, in _launch_kernel
return launch_kernel(kernel_cmd, **kw)

proc = Popen(cmd, **kwargs)

hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
PermissionError: [WinError 5] Access is denied

它最终会弹出一个提示：

我发现的建议是使用管理员权限运行 Spyder，但这并不能解决我的问题。我发现了一些其他建议来执行以下操作

根据@CarlosCordoba：“要解决此问题，OP 需要运行 conda update anaconda，然后在 Anaconda Prompt 中运行 conda update jupyter_client”

当我在 Anaconda cmd 提示符下以管理员权限运行 conda update anaconda 时，会发生这种情况

有什么帮助吗？我只对 Python 有一点了解，并在课堂上使用它进行数学优化。

编辑：一些额外的信息。当我尝试从 Anaconda Navigator 启动 Spyder 时，它只会永远旋转，永远不会启动。

我修好了！我做了一个软启动，然后在 Anaconda 终端中运行spyder --reset。然后，以管理员权限运行 Spyder，它就可以连接了！
