anaconda - anaconda-navigator 不会使用 UnicodeDecodeError 启动

问题描述

问题描述：

重新启动后，命令 $ anaconda-navigator 将不再启动 Anaconda Navigator。

而是生成以下跟踪堆栈：

Traceback (most recent call last):
  File "/home/penguin/anaconda3/bin/anaconda-navigator", line 11, in <module>
    sys.exit(main())
  File "/home/penguin/anaconda3/lib/python3.6/site-packages/anaconda_navigator/app/main.py", line 99, in main

    self.read(self.filename(), encoding='utf-8')
  File "/home/penguin/anaconda3/lib/python3.6/configparser.py", line 697, in read
    self._read(fp, filename)
  File "/home/penguin/anaconda3/lib/python3.6/configparser.py", line 1015, in _read
    for lineno, line in enumerate(fp, start=1):
  File "/home/penguin/anaconda3/lib/python3.6/codecs.py", line 321, in decode
    (result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd6 in position 3: invalid continuation byte

故障排除尝试

首先，我尝试过：

source ~/anaconda3/bin/activate root
anaconda-navigator

基于以下评论： https ://github.com/ContinuumIO/anaconda-issues/issues/1580

接下来，我尝试过：

$ anaconda-navigator --reset

然而，这导致：

Anaconda Navigator 配置重置...

解决方案

故障排除

首先，尝试重置导航器。 

$ anaconda-navigator --reset

上述命令应该删除 ~/.anaconda 中损坏的日志文件，但如果这不起作用或导致错误，请尝试手动删除日志文件。

$ rm -rf /home/$USER/.anaconda

最后，如果这不起作用，请尝试：

$ conda install anaconda-clean
$ conda-clean --yes
