为什么在尝试安装pyquery python模块时收到此错误?

[英]Why am I receiving this error when trying to install pyquery python module?

我正在使用以下命令

!pip install pyquery

我可以安装其他模块。 有人知道为什么会这样吗? 谢谢!

Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?
Perhaps try: xcode-select --install

我尝试安装libffi-devel,libxml2-devel,libxslt-devel,它解决了这个问题。 我正在使用CentOS 7。

src / lxml / includes / etree_defs.h:14:10:致命错误:找不到“ libxml / xmlversion.h”文件

包括“ libxml / xmlversion.h”

我遇到过这种类型的错误。 在大多数情况下,安装共享库开发包时,模块需要对其进行修复。

在Debian中,libxml2-dev具有libxml2 pacakge的所有头文件。 libxml2:amd64 / jessie 2.9.1 + dfsg1-5最新libxml2-dev:amd64 / jessie 2.9.1 + dfsg1-5最新

lxml模块需要libxml2-dev和libxslt1-dev。
