If you've had a 10.7 , I'd ask "have you latest X-Code installed?", because I got no errors just now. 如果您使用的是10.7 ，我会问“您是否安装了最新的X-Code ？”，因为我现在没有错误。
But instead I will ask: did you try/consider easy_install or pip install ? 但是我会问：您是否尝试过/考虑使用easy_install或pip install ？

You're using an alpha release of Python 2.7.0, an alpha release for which setuptools , which is used by lxml's setup.py , doesn't work. 您正在使用的是Python 2.7.0的Alpha版本，该Alpha版本setuptools使用lxml的setup.py使用的setuptools 。 Setuptools relies on an implementation detail of distutils.sysconfig (the _config_vars attribute) that was changed in the early Python 2.7 alpha releases, and reverted later in the release process (to un-break setuptools, in all likelyhood.) Setuptools依赖于distutils.sysconfig （ _config_vars属性）的实现细节，该实现细节在早期的Python 2.7 alpha发行版中已更改，并在发行过程的稍后阶段恢复（很可能恢复为不间断的setuptools）。

It's a good idea to install alpha releases to test if your own software works in the newer Python version, but you should not keep using them after newer versions are released, and certainly not after the final release has been made. 安装alpha版本以测试您自己的软件是否可以在较新的Python版本中运行是个好主意，但您不应在新版本发布后继续使用它们，当然也不能在最终版本发布后继续使用它们。 In this case, two more patchreleases were made later; 在这种情况下，稍后又发布了两个补丁版本。 you should really install those instead. 您应该真正安装它们。
