Question

我在虚拟环境中安装odoo系统。我在安装lxml模块时遇到问题。

我正在使用“pip --trusted-host pypi.python.org install lxml”命令，但是收到错误。我试图下载源，但发生相同的错误。我在Linux下使用Python 2.7.9：

(odoo)odoo@des [~]# python -V
Python 2.7.9
(odoo)odoo@des [~]# uname -a
Linux des.desytec.com 2.6.32-042stab104.1 #1 SMP Thu Jan 29 12:58:41 MSK 2015 x86_64 x86_64 x86_64 GNU/Linux

我已经阅读了很多关于这个问题的网页。有人说这是一个内存问题而其他人说libxml丢失了。这两种情况都不适用于我。还有什么呢？

Answer 1

我有类似的问题。一切都是通过设置几个库来决定的

sudo apt-get install libxslt1-dev libxml2-dev

已找到解决方案，感谢one和second

Answer 2

从Installing lxml您可以看到最新的lxml需要 libxml2版本2.7.0或更高版本和 libxslt版本1.1.23或更高版本，这是＃39;已安装在您的系统上。

你可以：

更新您的libxslt， e.x。下载rpm here
如果您的系统没有正确的版本支持（例如 CentOS 5 ），您可以选择 lxml 2.2.2 等订单版本这也适用于很多情况。

错误：未知的分发选项：'bugtrack_url'
