报错

在终端输入 “anaconda-navigator” 启动 Anaconda-Navigator时，报错：
UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0xb4 in position 0: invalid start byte

导致启动图标卡在 Loading Application不动。

原因

python常见的不认识编码的问题。

解决方案

点进去最后那个文件，找到含有该行代码的位置（我的有两行差不多的，在45行、46行）
stderr = ansi_utlils.escape_ansi(raw_stderr.decode())
改成（在decode函数里加入参数encoding=‘utf8’, errors=‘ignore’)

stdout = ansi_utlils.escape_ansi(raw_stdout.decode(encoding='utf8',errors='ignore'))
stderr = ansi_utlils.escape_ansi(raw_stderr.decode(encoding='utf8',errors='ignore'))

保存后重新在命令行中启动 “anaconda-navigator” 即可。
