参照博客:http://blog.csdn.net/k3v1n1990s/article/details/72975528?utm_source=itdadao&utm_medium=referral

在navigator的日志目录:
C:\Users\xx\.anaconda\navigator\logs\navigator.log

下发现了和原博主一样的问题: 

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again

 

按照博主的方法更新了Navigator,解决了问题。

 

更新请使用科学上网.......你懂得的。
