在Windows命令行环境下启动Python3.6，报如下错误
C:\Users\gaozh>python

File "C:\Anaconda3\lib\site-packages\pyreadline\rlmain.py", line 165, in read_history_file

for line in open(filename, 'r'):
UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 407: illegal multibyte sequence
解决办法
解决这个问题的方法就是修改文件 C:\Anaconda3\lib\site-packages\pyreadline\lineeditor\history.py 中对应的第82行的代码，添加编码格式为 utf-8，然后重新启动Python即可。
