我正在尝试使用pip安装库。这个问题出现在gevent、psycopg2和greenlet中。问题似乎是我的电脑找不到应该随XCode 4一起出现的特定C编译器:gcc-4.2。这里有一个示例(虽然也在virtualenv中进行了尝试)。

您可能会问:
1)您是否尝试使用virtualenv?
是的。我尝试将一个预先存在于/usr/bin/目录中的gcc建立符号链接,如下所示:
ln -s /usr/bin/gcc gcc-4.2
ln -s /usr/bin/gcc-4.2 gcc-4.2
ln -s /usr/bin/gcc gcc
这些方法都没有起作用。
2) 你尝试重新安装XCode了吗?
是的。
3) 你安装了XCode命令行工具吗?
是的。
4) 你确定已经安装了gcc吗?
**********s-MacBook-Pro:~ sanjay$ gcc
i686-apple-darwin11-llvm-gcc-4.2: no input files
5) Python 安装?
************s-MacBook-Pro:~ ******$ python
Python 2.7.3 (v2.7.3:70274d53c1dd, Apr 9 2012, 20:52:43)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
有什么想法是出了什么问题以及如何解决它吗?
我还尝试安装了这个:https://github.com/kennethreitz/osx-gcc-installer。我不知道还能尝试什么。当涉及到Unix编码/安装方面的事情时,我是一个新手,如果有些地方做得很糟糕,请指出。
谢谢!
