jupyter notebook error

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe5 in position 4: ordinal not in range(128)

1. vim ~/.bashrc
adding
2. export LANG=en_US:UTF-8
3. export LANGUAGE=en_US:en
4. source ~/.bashrc

这样jupyter notebook 解决了，但是终端里会显示不了中文，所以，我把它创造性的改成

2. export LANG=zh_CN.UTF-8
3. unchanged

problem solved
