This sound silly. But It works for me. I am using ubuntu. While Installing virtualenv through apt-get install I faced problems. But I got working with pip install virtualenv.
这听起来很傻。但它对我有用。我正在使用 ubuntu。在通过 apt-get install 安装 virtualenv 时，我遇到了问题。但是我开始使用 pip install virtualenv。
sudo pip uninstall virtualenv
sudo apt-get purge python-virtualenv
sudo pip install virtualenv
