在 python 中安装 lxml 模块

在运行 Python 脚本时，我得到了这个错误

  from lxml import etree
ImportError: No module named lxml

现在我尝试安装 lxml

sudo easy_install lmxl

但它给了我以下错误

Building lxml version 2.3.beta1.
NOTE: Trying to build without Cython, pre-generated 'src/lxml/lxml.etree.c' needs to be available.
ERROR: /bin/sh: xslt-config: not found


** make sure the development packages of libxml2 and libxslt are installed **

使用 libxslt 的构建配置

src/lxml/lxml.etree.c:4: fatal error: Python.h: No such file or directory
compilation terminated.
error: Setup script exited with error: command 'gcc' failed with exit status 1

You need to install Python's header files (python-dev package in debian/ubuntu) to compile lxml. As well as libxml2, libxslt, libxml2-dev, and libxslt-dev:

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

Just do:

sudo apt-get install python-lxml

For Python 2 (e.g., required by Inkscape):

sudo apt-get install python2-lxml

If you are planning to install from source, then albertov's answer will help. But unless there is a reason, don't, just install it from the repository.

I solved it upgrading the lxml version with:

pip install --upgrade lxml

If you're running python3, you'll have to do:

pip3 install lxml

For RHEL/CentOS, run "python --version" command to find out Python version. E.g. below:

$ python --version
Python 2.7.12

Now run "sudo yum search lxml" to find out python*-lxml package.

$ sudo yum search lxml
Failed to set locale, defaulting to C

python26-lxml-docs.noarch : Documentation for python-lxml
python27-lxml-docs.noarch : Documentation for python-lxml
python26-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt
python27-lxml.x86_64 : ElementTree-like Python bindings for libxml2 and libxslt

Now you can choose package as per your Python version and run command like below:

$ sudo yum install python27-lxml.x86_64

If you are encountering this issue on an Alpine based image try this :

apk add --update --no-cache g++ gcc libxml2-dev libxslt-dev python-dev libffi-dev openssl-dev make

// pip install -r requirements.txt

For python 3 this worked for me

sudo apt-get install python3-lxml
