python easy_install fails with "assembler for architecture ppc not installed" on Mac OS X

/usr/libexec/gcc/powerpc-apple-darwin10/4.2.1/as: assembler (/usr/bin/../libexec/gcc/darwin/ppc/as or /usr/bin/../local/libexec/gcc/darwin/ppc/as) for architecture ppc not installed
Installed assemblers are:
/usr/bin/../libexec/gcc/darwin/x86_64/as for architecture x86_64
/usr/bin/../libexec/gcc/darwin/i386/as for architecture i386
I'm a pretty big noob at this stuff (I've learned to use python and unix a bit, but I've never had to deal with installation.) Earlier I was getting an error related to gcc-4.2 not being found, and I found some posts that recommended reinstalling XCode. I went with 4.0 (bad choice?) and now I get this. I've got no idea what to do at this point.
我是这个东西的一个非常大的菜鸟（我已经学会了使用 python 和 unix，但我从来没有处理过安装。）早些时候我收到了一个与 gcc-4.2 相关的错误没有找到，我发现了一些建议重新安装 XCode 的帖子。我选择了 4.0（错误的选择？），现在我明白了。我现在不知道该怎么办。

This happened for me after having upgraded to XCode 4; I haven't had time to figure out what went wrong during the upgrade (or whether this is the intended behaviour), but the following workaround works for me:
升级到 XCode 4 后，这发生在我身上；我没有时间弄清楚升级过程中出了什么问题（或者这是否是预期的行为），但以下解决方法对我有用：
sudo env ARCHFLAGS="-arch i386" easy_install whatever
The ARCHFLAGStrick works with setup.pyas well:
这个ARCHFLAGS技巧也适用于setup.py：
env ARCHFLAGS="-arch i386 -arch x86_64" python setup.py install

I found another solution herewhich solves the problem once and for all. It turns out XCode4 still has the ppc assembler. You just need a symlink to it in the right place:
我在这里找到了另一个解决方案，它可以一劳永逸地解决问题。事实证明，XCode4 仍然具有 ppc 汇编器。你只需要在正确的地方有一个符号链接：
$ sudo ln -s /Developer/Platforms/iPhoneOS.platform/Developer/usr/libexec/gcc/darwin/ppc /Developer/usr/libexec/gcc/darwin
$ sudo ln -s /Developer/Platforms/iPhoneOS.platform/Developer/usr/libexec/gcc/darwin/ppc /usr/libexec/gcc/darwin
Fixed the problem for me with XCode4 installed on Snow Leopard.
解决了我在 Snow Leopard 上安装 XCode4 的问题。
EDIT: I tried other solutions, which worked in some cases, but invariably encountered a package that hardcoded the PPC requirement somewhere. Providing the PPC assembler got rid of all these problems once and for all.
编辑：我尝试了其他解决方案，这些解决方案在某些情况下有效，但总是遇到一个在某处硬编码 PPC 要求的程序包。提供 PPC 汇编器一劳永逸地解决了所有这些问题。

For me, the key was the ppc assembler, not the ARCHFLAGS stuff. But, the suggestion above didn't work; I didn't have the files in those locations. But with some tinkering and poking around, I found that I did have the ppc assember at /usr/bin/as. I first tried sudo ln -s /usr/bin/as /usr/libexec/as/ppc/as, but that failed (something about could not fork process...??). So I ended up just doing sudo cp /usr/bin/as /usr/libexec/as/ppc/as, and that worked (I think I had to do some sudo mkdirs along that path, as well).
对我来说，关键是 ppc 汇编程序，而不是 ARCHFLAGS 的东西。但是，上面的建议没有用；我在这些位置没有文件。但是经过一些修补和摸索，我发现我确实在/usr/bin/as. 我第一次尝试sudo ln -s /usr/bin/as /usr/libexec/as/ppc/as，但失败了（关于无法分叉进程......？？）。所以我最终只做了sudo cp /usr/bin/as /usr/libexec/as/ppc/as，并且奏效了（我想我也必须sudo mkdir沿着这条路做一些事情）。

Using the system Pythons on Mac OS X 10.6, you'll need to have the gcc-4.2 from the Apple Xcode Developer Tools installed to build extension modules, like with Appscript. Other products may need the Xcode gcc-4.0 so you should install them both. They co-exist just fine.
在 Mac OS X 10.6 上使用系统 Python，您需要安装来自 Apple Xcode Developer Tools 的 gcc-4.2 来构建扩展模块，就像使用 Appscript。其他产品可能需要 Xcode gcc-4.0，因此您应该同时安装它们。它们共存得很好。
