Question

我正在尝试安装PyExerces。但是我遇到了gcc编译错误。在Ubuntu中的python中这种事情正常吗？

（我几乎没有在Python中找到XQuery库，它是XQilla，XQilla需要PyExerces，而“ pip install PyXerces”给出了以下错误。还有用于python Xquery lib的Zorba。但这是一个过时的旧项目，其必需的软件包不再适用于Ubuntu 18。 python发生了什么？ :)无法找到适用于Python的XQuery库非常令人失望。）

Answer 1

2014年发布的0.0.1版。您确定该软件包可用吗？反正...

这是程序包中的错误。 distribution at PyPI包含Python源代码和C ++文件，但不包含文件。标头在the repository中可用。尝试直接从Github安装：

pip install git+https://github.com/mugwort-rc/pyXerces.git#egg=pyXerces

您需要一些其他依赖项。当编译开始需要Boost库时，我停了下来。

src / Xerces.cpp：13：10：致命错误：dom / DOMAttr.h：没有此类文件或目录
