python – 为什么我在尝试设置virtualenv时会收到此错误(与pip和easy_install相关)？

我正在尝试创建一个Flask应用程序来推送到Heroku.当我尝试在文件夹中创建virtualenv时,我抛出了这个错误：

photo-crawl › sudo virtualenv venv --distribute

似乎由于某种原因,virtualenv没有把它应该放入venv / bin文件夹的所有内容.现在,只有python和两个别名,python2和python2.7在那里.

谢谢！

解决方法:

我相信这是由旧版virtualenv和/或pip中的错误引起的.看起来你正在使用virtualenv 1.8.4和pip 1.2.1.你有可能升级到最新的virtualenv和pip(目前virtualenv 1.9.1和pip 1.3.1)？

如果你有安装权限,这应该这样做：

pip install pip --upgrade
pip install virtualenv --upgrade

此时运行相同的命令(即sudo virtualenv venv –distribute)应该给你你想要的.
