lipo: 无法识别架构类型：/var/folders/

Question

我在Mac OSX Snowleopard上尝试安装lxml，但一直出现错误：

lipo: can't figure out the architecture type of: /var/folders/

我已经安装了带有10.4 SDK支持的XCode，并且把gcc从4.2改成了4.0.1。

有没有什么线索？？？我用的是Python 2.6.1和Leopard 1.6.7。

Answer 1

我发现通过brew安装python可以很容易避免这些编译问题。如果brew无法链接这个公式，可以强制链接，方法是：

brew link --overwrite python

另外可以参考：http://docs.python-guide.org/en/latest/starting/install/osx/

Answer 2

你的Python可能遇到了架构问题。因为Xcode 4做了一些改变（不再支持10.4u SDK和gcc-4.0），所以在10.7 Lion系统上用这个Python来构建C扩展模块就变得不太实际了。你可以选择使用苹果自带的Python 2.7。

/usr/bin/python2.7

你也可以安装这个Python 2.7.3 Mac OS X 64位/32位的安装包。

我在用Python 2.7安装milk的时候也遇到了同样的问题。我没有按照Ali Elouafiq的答案解决我的问题，但我成功用系统自带的Python 2.6安装了milk。

所以，也许尝试其他版本的Python，看看能不能成功，是一种比较省钱的办法。
