Question

我正在尝试使用easy_install（和pip）安装lxml和pycrypto模块，但收到错误消息，如

Running lxml-2.3.4/setup.py -q bdist_egg --dist-dir /tmp/easy_install-kGsWMh/lxml-2.3.4/egg-dist-tmp-Gjqy3f

当我尝试安装pycrypto时，我遇到了类似的语法错误。我试过this answer但是徒劳无功。我尝试使用setuptools-0.6c11-py2.6.egg和setuptools-0.6c11-py2.7.egg设置python 2.6和2.7环境，但获得相同的输出。

我在网上搜索了很多，但无法找到解决方案。

编辑：我在macbook pro 2010上使用OSX 10.7，并安装了XCode 4和3

在尝试上面链接中的命令时，我用最新版本代替了。

python setup.py build --static-deps --libxml2-version=2.7.8  --libxslt-version=1.1.26 
sudo python setup.py install

我在另一篇文章中读过并试过这个

STATIC_DEPS=true sudo easy_install --allow-hosts=lxml.de,*.python.org lxml

解决方案：

@jdi建议我做了以下

$ brew install --use-llvm libxml2
$ brew install --use-llvm libxslt

从link安装了gcc，因为我仍然遇到选项1和2建议的问题

然后，这个

$ export ARCHFLAGS="-arch i386 -arch x86_64"
$ /usr/bin/python2.6 setup.py build
$ sudo /usr/bin/python2.6 setup.py install

或者，这将起作用

$ sudo env ARCHFLAGS="-arch i386 -arch x86_64" easy_install-2.6 lxml

同样适用于pycrypto

Answer 1

这是正确的表示您正在构建它：/Developer/usr/bin/../lib/gcc/powerpc-apple-darwin10，除非您使用旧的powerpc机器。

检查您正在运行的OSX的版本，以及用于构建lxml的命令。您可能需要在构建之前在shell中设置export ARCHFLAGS="-arch i386 -arch x86_64"，以避免它与ppc一起构建。不知道为什么你会得到一个古老的拱门。

另外，请确保安装了最新的Xcode。并且，如果您按照您发布的链接，逐字逐句，请确保您使用的是这些软件包的最新版本，而不是文字版本，因为该链接是3年。

如果所有其他方法都失败了，请安装homebrew并通过该软件包管理器进行安装。

更新： XCode 4.2+更新后缺少GCC 4.2的选项

选择一个

使用此简单指南安装gcc 4.2：
http://caiustheory.com/install-gcc-421-apple-build-56663-with-xcode-42
使用自制软件安装它：

brew tap homebrew/dupes
brew install homebrew/dupes/apple-gcc42
完全忽略gcc并将llvm与brew
一起使用
brew install --use-llvm libxml2

无法使用easy_install或pip在mac上安装
