import sys, os, re, subprocess

import _posixsubprocess

ImportError: dynamic module does not define module export function (PyInit__posixsubprocess)

-------------------------

瞎折腾后，检查发现：

echo $PYTHONPATH 是系统自带的那个，python2的：

/N/soft/rhel7/python/2.7.13a/lib/python2.7/site-packages，

未变成 python3的，/N/u/lily/anaconda3/lib/python3.7/site-packages

但是，我的 .zshrc文件并找不到，执行下面语句应该只是自己在创造了个文件：

vim ~/.zshrc
cat ~/.bashrc >> ~/.zshrc

未果多次后，博主强行解决方式：

export $PYTHONPATH="/N/u/lily/anaconda3/bin/:$PATH"

source ~/.bashrc
