解决 ModuleNotFoundError: No modul

• 系统：Centos
• python版本： python3.7
• 安装底层库：

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel python-devel python3-devel

解决 _bz2 只需要安装 zlib-devel bzip2-devel即可，如果你想避免以后遇到 _bz2 这样恶心的报错，那你听我的，全装了吧。

• 重新安装编译python3.7
• 测试导入 bz2 不报错

$python3.7
