Python pip 在安装过程中不构建依赖项
Python pip doesn't build dependencies during installation
Pip 似乎没有在我的 Ubuntu 服务器上从源代码构建依赖项，而它总是在我的 OS X 机器上这样做。例如，当我尝试在 conda 或 virtualenv（我都尝试过）环境中安装包 qiime 时，安装大量需要花费大量时间的东西需要几秒钟才能在我的 Mac 上进行编译。

当我尝试使用该包时，出现各种错误，证明 pip 并未真正编译任何依赖项。我该怎么办？例如，让我们尝试导入 pandas
In [1]: import pandas

我知道我可以手动构建所有内容，但我真的很想修复 pip。
在安装过程中将 --no-cache-dir 传递给 pip 似乎可以解决问题，但我不明白缓存与编译有什么关系。
