lxml 无法使用 python 3.7 安装

Question

我无法在 python 环境中安装 libxml 来安装 sofort\npython: Python 3.7.3\n已经做了： apt-get --reinstalll install python-dev libxml2-dev libxslt1-dev zlib1g-dev\n当尝试安装 libxml 时，它会调用关于 PyObject 的错误有这样的错误

\n\n

398                    (PY_VERSION_HEX >= 0x030600B1 && (cfunc)->flag == METH_FASTCALL ?  (*(__Pyx_PyCFunctionFast)(cfunc)->func)(self, &PyTuple_GET_ITEM(__pyx_empty_tuple, 0), 0, NULL)\n\n

sofort声明依赖项 lxml >= 3.5, < 4.0，因此pip使用最新的合适版本 lxml 3.8。版本比较老，不提供Python 3.7的轮子，只提供2.6-3.6。也许该版本与 Python 3.7 不兼容，无法从源代码编译。

降级到 Python 3.6。并 pingsofort作者进行升级。或者更好地向他们发送拉取请求。
