Question

我正在运行OSX 10.10.2，以及最新的自制Python 2.7.9安装。由于某种原因 - 并且因为我很少在virtualenvs之外工作，并且最近没有创建任何东西，我不能说当这个改变了 - pip现在尝试将其二进制文件写入/usr而不是自制二进制前缀。下面是pip本身的pip升级输出，以及二进制文件的版本/路径。我可以在我的环境中添加任何可能有助于此的内容。

这个问题的答案结果是~/.pydistutils.cfg的存在，由于尝试调整安装路径而导致其中包含此内容：

[install]
prefix=

这会将所有python包安装的前缀重写为''

因此，如果你的pip / setuptools开始做奇怪的事情，请先检查这个文件。

我的自制Python / pip试图在/ usr中安装二进制文件...为什么，我该如何解决？
