在Red Hat上安装lxml

Question

我正在尝试在服务器计算机（Red Hat 4.1.2-52）上为Python 3安装python-pptx。 我在安装其依赖项lxml时遇到了一些麻烦。 我试过单独安装所有的依赖（如建议在这里 ）。

# sudo yum install -y gcc libxml2 libxml2-devel libxslt libxslt-devel python-devel

这是# pip install lxml的完整回溯。

有什么想法我可能做错了吗？ 首先十分感谢！

如果有的话，这是这篇文章的重复，也没有得到解答...但是我们得到的错误消息略有不同。

Answer 1

我不使用Red Hat，但对您的建议是按照此处的说明进行操作：

sudo yum install make automake gcc gcc-c++ kernel-devel git-core -y 

sudo yum install python-devel -y 

sudo curl -o /tmp/ez_setup.py https://sources.rhodecode.com/setuptools/raw/bootstrap/ez_setup.py 

sudo /usr/bin/python /tmp/ez_setup.py 

sudo /usr/bin/easy_install pip 

sudo rm setuptools-*.tar.gz 

sudo pip install -i https://pypi.rhodecode.com/ --upgrade pip 

sudo pip install virtualenv 

这里的想法是，您将安装虚拟环境并在其下使用pip软件包，这在依赖关系方面既简单又可靠。

Answer 2

请不要使用sources.rhodecode.com和pypi.rhodecode.com，它们很快就会消失:)我们不再在RhodeCode内部镜像我们的python东西。
