最近购买了一台新Mac,并为Python和iOS开发设置了它。 Python工作正常 - 特别是pip'ing git repos有很多要求.txt依赖关系UNTIL我安装了Xcode,macports和Apple的命令行工具。
现在pip适用于单独安装(例如,pip install twilio),但每当我针对requirements.txt文件运行pip时,它都会失败(有或没有sudo):
pip install ./requirements.txt
Exception:
Traceback (most recent call last):

我的$PATH
值为
/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin
这看起来不同于“OS X 10.8升级后破解的Python点”线程。我很想知道macports在查看/System/Libary
和~/Library
之间是否存在冲突。
有什么想法吗?

如果要通过需求文件安装软件包,则需要--requirement/-r
选项:
$ pip install -r requirements.txt
