1.确保安装了 对应的库
// ubuntu安装命令
sudo apt-get install bzip2-devel
// centos安装命令
sudo yum install bzip2-devel

2.找到对应的 bzip2 的 .so 文件 _bz2.cpython-36m-x86_64-linux-gnu.so，可以用以下方法找，比如：
在python3.6环境下安装，位置在：/usr/lib/python3.6/lib-dynload/ 下
或者 在python3.6环境下安装，位置在： /usr/lib64/python3.6/lib-dynload/ 下
或者 如果找不到就用命令查找： find / -name _bz2.cpython

3.将该动态库的存入你安装的python的lib-dynload目录下，这个目录，一般是
/usr/lib/python3.6/lib-dynload/
或者
/usr/lib64/python3.6/lib-dynload/

或者自定义的python安装目录下：

./lib/python3.6/lib-dynload/
或

./lib64/python3.6/lib-dynload/

命令如下：

cp /usr/lib64/python3.6/lib-dynload/_bz2.cpython-36m-x86_64-linux-gnu.so /usr/local/python3/lib/python3.8/lib-dynload/_bz2.cpython-38m-x86_64-linux-gnu.so

需要注意的是python版本对应的名称。

之后再把python 重新编译一下，软连接可以不用重新弄。

或者把python卸载了重新安装一下。
