无法使用pip安装lxml

Question

这是我用来安装lxml的命令：

sudo pip install lxml

我在清理阶段收到以下消息：

Cleaning up...
Command /usr/bin/python -c "import setuptools,     tokenize;__file__='/private/tmp/pip_build_root/lxml/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-rUFjFN-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /private/tmp/pip_build_root/lxml
Storing debug log for failure in /Users/georgejor/Library/Logs/pip.log

在那之后，我得到了：

ImportError: No module named lxml

请帮忙。 谢谢！

以下输出来自pip.log：

Answer 1

只需安装这些东西：

sudo apt-get install libxml2-dev libxslt-dev  python-dev  python-setuptools

然后再试一次：

pip install lxml

Answer 2

这是一个类似的问题。

安装枕头（和PIL）时出错

你在使用MacOS吗？ 也许您可以尝试更新命令行工具并尝试'brew'工具。 如果没有，您可以尝试再次安装pip和easy_intall工具，并进行更新。

Answer 3

lxml有C依赖性，当我缺少libxslt或libxml2时，我经常遇到问题。 您确定所有非python依赖项都已安装吗？
