打开Anaconda Navigator时报错PermissionError: [WinError 5] 拒绝访问。

前一天关机前都没问题，第二天再打开Anaconda Navigator就报错了，网上搜了一下解决方法，在此记录一下。

报错内容：

Traceback (most recent call last):
File "C:\Users\\AppData\Local\Continuum\anaconda3\lib\site-packages\psutil\_pswindows.py", line 636, in wrapper
return fun(self, *args, **kwargs)
File "C:\Users\\AppData\Local\Continuum\anaconda3\lib\site-packages\psutil\_pswindows.py", line 706, in cmdline
ret = cext.proc_cmdline(self.pid)
PermissionError: [WinError 5] 拒绝访问。

During handling of the above exception, another exception occurred:

psutil.AccessDenied: psutil.AccessDenied (pid=5136)

解决方法：
1）使用管理员运行：conda prompt
2）执行命令 conda update anaconda-navigator
3）还是不行就试试命令：anaconda-navigator --reset

原博主第二步没成功，用了第三步。俺也一样。升级没动静，干脆直接reset就OK了。
