Question

我建立了一个新的virtualenv。从它内部，pip找不到任何发行版。在环境之外，它可以。这是输出：

(wagon-admin)[me@pjs-macbook-pro wagon-admin]$ pip install Django

我在OSX上，使用virtualenvwrapper创建了虚拟环境。 $ mkvirtualenv <env name>

所有包都会发生这种情况，而不仅仅是django。

Answer 1

我有同样的问题，但意识到我没有激活我的virtualenv。一旦我激活它，安装工作。不知道为什么。

查看您粘贴的命令行，看起来您已经激活了您的环境，但只是想为其他偶然发现这一点的人注意到这一点。

Answer 2

我更新到python 2.7，现在一切正常。
