ImportError: No module named ‘_bz2’

解决方案：参考链接

1. we can download file:_bz2.cpython-38-x86_64-linux-gnu.so.

   downloads this file: https://pan.baidu.com/s/1iPuEBYnUABWf94QM9fQZgQ 提取码: nw2g

2. then renames file because i use python3.9, this file is python3.8 :

   cp _bz2.cpython-38-x86_64-linux-gnu.so /usr/local/python3/lib/python3.9/lib-dynload/
   

   注意 python路径切换为自己实际的Python路径。

3. Modify file permissions if it’s doesn‘t work

   chmod +x _bz2.cpython-38-x86_64-linux-gnu.so
