Question

我正在尝试安装PyExerces。但是我得到了gcc编译错误。这种事情在Ubuntu的python中正常吗？

(我在Python中几乎找不到XQuery库，它是XQilla，XQilla需要PyExerces，"pip install PyXerces“给出以下错误。还有一个用于python Xquery lib的Zorba。但这是一个过时的项目，其所需的软件包在Ubuntu 18中不再可用。python是怎么回事？:)找不到Python的XQuery库非常令人失望。)

版本0.0.1发布于2014年。你确定这个包是可用的吗？不管怎样，…

这是包中的错误。distribution at PyPI包括Python源代码和C++文件，但不包括文件。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

您需要一些额外的依赖项。当编译开始需要Boost库时，我停止了编译。
