我有一个MacO Catalina，现在我要进行下一个安装：
python -V ==> python 3.7.5
python2 -V ==> python 2.7.16
点-V ==>点20.0.2
找不到pip2 -V ==>命令
pyenv版本==> 3.7.5（由/Users/dmuino/.pyenv/version设置）
每次启动终端时，都会显示下一个警告：

/System/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/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.
你能帮我吗？
