Running virtualenv with interpreter /usr/bin/python2.7
New python executable in play/bin/python2.7
Also creating executable in play/bin/python

【问题讨论】：

virtualenv --version 显示的是什么版本？

标签： python virtualenv python-2.7

【解决方案1】：

见https://github.com/pypa/virtualenv/issues/76

要与 Python 2.7 一起使用，请将 virtualenv 升级到 1.5.1 或更高版本。您可以通过virtualenv --version查看您当前的版本。
