Mac OS-X Mountain Lion上的GCC-4.2错误，无法使用pip / virtualenv安装某些软件包 [英] GCC-4.2 error on Mac OS-X Mountain Lion, unable to install some packages with pip / virtualenv
问题描述
我看到一个非常恼人的错误，我不知道该如何处理。这似乎是相当普遍的，我已经尝试了几乎所有我能找到的解决方案，但都无济于事。
我正在尝试使用pip安装库。 gevent，psycopg2和greenlet遇到了这个问题。这个问题似乎是我的电脑无法找到一个特定的C编译器，它应该提供XCode 4：gcc-4.2。这里有一个例子（尽管也是在virtualenv中进行的尝试）。

您可能会问的问题：
1）您是否尝试过使用virtualenv？
是的。我尝试将以前存在的gcc（它存在于/ usr / bin /目录中）象符号链接： s / usr / bin / gcc gcc-4.2
ln -s /usr/bin/gcc-4.2 gcc-4.2
ln -s / usr / bin / gcc gcc
没有一个能够工作。
<2>您尝试重新安装XCode吗？
是。
3）您是否安装了XCode命令行工具？
是。
4）你确定你有gcc吗？

关于什么可能是错误的以及如何解决它的任何想法？
我也尝试安装这个： https://github.com / kennethreitz / osx-gcc-installer 。我不知道还有什么可以尝试的。在这个unix-y编码/安装方面，我是一个新手，所以如果有什么我做得非常糟糕，请指出。
谢谢！
pycrypto安装无法在virtualenv中编译时出现同样的问题。通过海报jiaaro在此主题中找到解决方案：

您需要安装Xcode 4.4（从应用商店），然后在
内打开xcode >首选项（或按Cmd +，）
然后打开下载选项卡并安装命令行工具。
在Mac OSx Mountain Lion 10.8我使用命令行工具安装了xCode 4.3。我做了更新到xCode 4.4，它仍然没有工作。即使安装了Xcode，显然也不会自动下载新的命令行工具。正如jiaaro的帖子所述，你必须明确地下载命令行工具。
当前版本的gcc在下面，并且成功地为我sudo pip install virtualenv包无需sym链接。

I'm seeing a very annoying bug that I don't really know how to deal with. It seems to be pretty common, and I've tried nearly every solution that I could find to no avail.
I'm trying to install libraries using pip. This problem was encountered with gevent, with psycopg2, and with greenlet. The issue seems to be that my computer can't find a particular C compiler that should come up with XCode 4: gcc-4.2. Here's an example (though attempts were made in a virtualenv as well).

Things you might ask:
1) Did you try using a virtualenv?
Yes. And I attempted to symlink a preexisting gcc (which is present in the /usr/bin/ directory) like so:
ln -s /usr/bin/gcc gcc-4.2
ln -s /usr/bin/gcc-4.2 gcc-4.2
ln -s /usr/bin/gcc gcc
None of which worked.
2) Did you try reinstalling XCode?
Yes.
3) Did you install the XCode Command Line Tools?
Yes.
4) Are you sure you have gcc?
**********s-MacBook-Pro:~ sanjay$ gcc

5) Python installation?

Type "help", "copyright", "credits" or "license" for more information.
Any ideas on what might be wrong and how to fix it?
I also tried installing this: https://github.com/kennethreitz/osx-gcc-installer . I have no idea what else to try. I'm a bit of a new kid on the block when it comes to this unix-y coding / installation things, so if there is something I'm doing very badly please point it out.
Thanks!
Same problem with pycrypto install failing to compile in a virtualenv. Found the solution in this thread by poster jiaaro: https://gist.github.com/3179227#gistcomment-379913
You need to install Xcode 4.4 (from the app store) and then, within xcode open Xcode > Preferences (or press Cmd + ,) then open the downloads tab and install the Command Line Tools.
On Mac OSx Mountain Lion 10.8 I had xCode 4.3 installed WITH the command line tools. I did the update to xCode 4.4 and it still didn't work. Xcode does not automatically download the new command line tools apparently even if you had them installed. As the post from jiaaro states, you have to explicitly download the command line tools again.
Current version of gcc is below and does successfully sudo pip install packages in virtualenv for me with no need to sym link.
