How do I install lxml on Mac OS X 10.7.4? I have exhausted all options
提问by ThinkCode
Tried various avenues but no luck. I am using a MBP with 10.7.4. I don't remember the last time I had so many problems installing anything with Python on my Mac. Please help me use lxml on my local machine and not rely on SVN commits, updates to remotely run on the Linux machine.
尝试了各种途径，但没有运气。我正在使用 10.7.4 的 MBP。我不记得上次我在 Mac 上使用 Python 安装任何东西时遇到这么多问题是什么时候。请帮助我在本地机器上使用 lxml，而不是依赖 SVN 提交、更新以在 Linux 机器上远程运行。

I first installed MacPortsand then:
我首先安装了MacPorts，然后：
$ sudo port install python27 py27-lxml
And this gave me a functioning lxml installation.
这给了我一个正常运行的 lxml 安装。
Regarding your error messages, you appear to be missing the compiler command that pipis using to build lxml(llvm-gcc-4.2). Do you have the OS X development tools installed? You should find that file in /usr/bin/llvm-gcc-4.2; if it's not there, you probably need to download and install the development package.
关于您的错误消息，您似乎缺少pip用于构建的编译器命令lxml(llvm-gcc-4.2)。您是否安装了 OS X 开发工具？您应该在/usr/bin/llvm-gcc-4.2; 中找到该文件。如果它不存在，您可能需要下载并安装开发包。
You can install the XCode developer tools via the App Store. If you read the comments in the app store, you'll note that in order to make the command line tools available you need to install them separately. In XCode, go to Preferences->Downloads and download the "Command line tools" package.
您可以通过 App Store 安装 XCode 开发人员工具。如果您阅读应用商店中的评论，您会注意到为了使命令行工具可用，您需要单独安装它们。在 XCode 中，转到 Preferences->Downloads 并下载“命令行工具”包。

To future users who are going over this page, here is a step-by-step guide to installing lxml on Mac OSX.
对于浏览此页面的未来用户，这里是在 Mac OSX 上安装 lxml 的分步指南。
Go to Xcode, and go to Preferences, and then go to the Downloads tab, and select "Command Line Tools". Download Command Line Tools
Go to Applications, then Utilities, and then Terminal, and open the Terminal. In terminal, type "easy_install pip". Note: If it says "error: /usr/local/bin/pip: Permission denied", then type "chmod 777 /usr/local/bin/". now try step 2 again.
Type: pip install "Cython>=0.18"
After it is finished, type: pip install lxml
Open up python IDLE and test if you can import lxml, have fun!
转到 Xcode，然后转到首选项，然后转到下载选项卡，然后选择“命令行工具”。下载命令行工具
依次转到应用程序、实用程序和终端，然后打开终端。在终端中，输入“easy_install pip”。注意：如果显示“错误：/usr/local/bin/pip：权限被拒绝”，则输入“chmod 777 /usr/local/bin/”。现在再次尝试第 2 步。
类型：pip install "Cython>=0.18"
完成后，输入：pip install lxml
打开python IDLE，测试是否可以导入lxml，玩得开心！

I had to do: "sudo port uninstall py-lxml", "sudo port uninstall py24-lxml", and "sudo port install py27-lxml" and then I uninstalled lxml with pip, and re-installed with pip and it worked!
我不得不这样做：“ sudo port uninstall py-lxml”，“ sudo port uninstall py24-lxml”和“ sudo port install py27-lxml”然后我用pip卸载了lxml，并用pip重新安装，它起作用了！
