在Ubuntu中安装lxml的问题

Apu*_*Jha 10 python lxml pip python-2.7

当我这样做时出现以下错误:pip install lxml 

You are using pip version 6.0.8, however version 7.1.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

我已经尝试过这个:sudo apt-get install zlib1g-dev在"pip install"之前阅读这个答案:无法在ubuntu中安装lxml verison 3.3.5

但没有帮助.另外,尝试安装python-dev,python3-dev,lib-eventdev也没有帮助.

另外,尝试这样做:STATIC_DEPS = true pip install lxml阅读:http://lxml.de/installation.html

也没有帮助!如果您能事先提出建议,将非常感激.

输出状态** make sure the development packages of libxml2 and libxslt are installed **.你做到了吗？

另外,有没有特别的原因你使用pip安装而不是安装python-lxmlUbuntu附带的软件包？除非您有其他理由,否则应首选安装您的发行包.

如果您不需要 PyPI 的特定版本，则始终可以使用为 Ubuntu 打包的版本。

$ sudo apt-get install python-lxml

...然后在您的 virtualenv 中允许系统站点包。

更新：

为了澄清... pip 默认从 PyPI 安装 python 包。然而，许多 python 软件包也为 Ubuntu 打包并存储在 Ubuntu 档案中，您可以通过系统软件包管理器 (apt-get) 安装它们，而不是使用 pip。这会很有帮助，因为 Ubuntu 软件包已经编译完毕，并且会引入它们需要的任何依赖项。

默认情况下，virtualenv 创建一个隔离的 python 环境，因此您无权访问系统包（使用 apt-get 安装的）。但是，您可以在 virtualenv 中允许系统站点包。

例如，让我们从系统包中安装 lxml，创建一个名为“ENV”的 virtualenv 以允许访问系统包，然后导入 lxml 来验证它是否有效：

$ sudo apt-get install python-lxml
$ virtualenv --system-site-packages ENV
$ source ENV/bin/activate
(ENV)$ python -c "import xml"
