安装 virtualenvwrapper 时出错

Question

我在尝试安装 virtualenvwrapper 时遇到如下所示的错误。我做错了什么？

我使用的是 Mac OSX。我正在使用 pip 作为 sudo 进行安装。如果我在没有 sudo 的情况下使用 pip，我也会得到同样的错误

我没有在 Google 中看到此特定错误。

我确实得到了很多搜索不太具体的查询的结果：

"sudo pip install virtualenvwrapper" error

但是，这些结果有多种解决方案（变通方法），我不确定它们是否适合我当前的问题。

Answer 1

我在某个时候遇到了这个确切的问题。以下2个步骤解决了这个问题：

1. 在 sudo 命令中使用 -H 标志

2. 像这样忽略安装“六”包

   pip install virtualenvwrapper --ignore-installed 6

希望这会有所帮助。另一方面，最好通过 Brew 包管理器安装它。

Answer 2

我认为它已经覆盖了here。

我不想听起来刺耳或令人讨厌，但是这个问题很容易用谷歌搜索，并且在整个网络和 StackOverflow 上都得到了一次又一次的回答。
