在python中安装lxml模块

在运行python脚本时，出现此错误

  from lxml import etree
ImportError: No module named lxml

现在我尝试安装lxml

sudo easy_install lmxl

但这给了我以下错误

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

做就是了：

sudo apt-get install python-lxml

对于Python 2（例如，Inkscape要求）：

sudo apt-get install python2-lxml

如果您打算从源代码安装，那么albertov的答案将有所帮助。但是除非有原因，否则不要从存储库中安装它。

我解决了使用以下命令升级lxml版本的问题：

pip install --upgrade lxml

您需要安装Python的头文件（debian / ubuntu中的python-dev软件包）才能编译lxml。以及libxml2，libxslt，libxml2-dev和libxslt-dev：

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

如果您正在运行python3，则必须执行以下操作：

pip3 install lxml

对于RHEL / CentOS，运行“ python --version”命令以查找Python版本。例如：

$ python --version 
  Python 2.7.12

现在运行“ sudo yum search lxml”以找出python * -lxml软件包。

$ 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

现在，您可以根据您的Python版本选择包并运行如下命令：

$ sudo yum install python27-lxml.x86_64

对于python 3，这对我有用

sudo apt-get install python3-lxml

如果您在基于Alpine的图像上遇到此问题，请尝试以下操作：

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

// pip install -r requirements.txt
