关于pip3 install virtualenvwrapper 报错:ERROR: Could not find a version that satisfies the requirement pbr (from versions: none)

ubuntu18.04中安装python虚拟环境时报错:

关于pip3 install virtualenvwrapper 报错:ERROR: Could not find a version that satisfies the requirement pbr (from versions: none)

 

网上找了很久没解决,后来一想不就是没找到这个pbr的版本嘛,也不知道这是什么东西,直接安装它就得了:

 再去装虚拟环境就可以了。
