在Ubuntu上使用Python 2.7创建virtualenv沙盒失败？

Question

为什么virtualenv会抱怨缺少“_weakrefset”？

laptop:~/sandbox$ virtualenv --python=/usr/bin/python2.7 --no-site-packages play
Running virtualenv with interpreter /usr/bin/python2.7
New python executable in play/bin/python2.7
Also creating executable in play/bin/python

ERROR: virtualenv is not compatible with this system or executable

virtualenv --version 显示的是哪个版本？ - robots.jpg

Answer 1

请参见https://github.com/pypa/virtualenv/issues/76

如果您使用的是Python 2.7，请将virtualenv升级到1.5.1或更高版本。您可以使用virtualenv --version命令检查当前版本。
