Linux：CentOS7
python：
系统默认python版本2.7，利用python启动
自己安装python版本3.8，利用python3启动
问题描述：
在上述环境中利用virtualenvwrapper创建虚拟环境时，发生以下错误
/usr/bin/python: No module named virtualenvwrapper
virtualenvwrapper.sh: There was a problem running the initialization hooks.
If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is set properly.

原因是在virtualenvwrapper.sh中有以下代码
# Locate the global Python where virtualenvwrapper is installed.
if [ "${VIRTUALENVWRAPPER_PYTHON:-}" = "" ]
then
VIRTUALENVWRAPPER_PYTHON="$(command \which python)"
fi
所以，在virtualenvwrapper初始化时，命令“which python”调用的是python2.7，而我的virtualenvwrapper是由pip3下载，所以会有错误“No module named virtualenvwrapper”
解决办法：
直接修改其command语句
VIRTUALENVWRAPPER_PYTHON="$(command \which python3)"
