Question

我使用vagrant和virtualenv / virtualenvwrapper构建开发环境。最近，我的流浪盒正确地停止了配置。似乎virtualenvwrapper将不再安装。我试图追查改变了什么。 发生了什么变化？

我的Vagrantfile和install.sh文件位于：https://gist.github.com/ErikEvenson/9763878。请注意，此错误发生在网络框上。

这是我在尝试安装virtualenvwrapper时遇到的错误：

艾瑞克，虽然你的答案可能有用，但我没有必要这么想。你有没有尝试过apt-get install virtualenvwrapper？

我问的原因是ubuntu已经拥有你＆＃34; sudo apt-get install python-virtualenv＆＃34; （也安装python-pip），我也没有问题apt-get install＆virthualenvwrapper。唯一的区别是你需要＆＃34;来源/etc/bash_completion.d/virtualenvwrapper"在你的bashrc而不是/usr/local/bin/virtualenvwrapper.sh。

你仍然可以尝试一下你已经做过的事情（如果它不起作用，不要怪我！）：

$ sudo apt-get uninstall python-pip
$ sudo apt-get install python-pip
$ sudo pip uninstall virtualenvwrapper
$ sudo apt-get install virtualenvwrapper
then add source /etc/bash_completion.d/virtualenvwrapper to ~/.bashrc

这样的事情。祝你好运！

Answer 2

在执行pip install --upgrade pip之后运行apt-get install python-pip似乎已经完成了这个伎俩。这使得pip达到1.5.4并避免上述错误。此外，请务必使用/user/local/bin/pip作为配置脚本的其余部分。

我不知道是什么改变了让我的配置依赖于pip＆gt;但是1.0。很高兴知道我可以锁定这种依赖。

你可以试试 sudo apt-get install python-virtualenv virtualenwrapper。
