如何安装Python3.6的lpsolve？

Question

所以我用python3.6运行时创建一个Docker容器。我需要一个用于python的UX64版本的lp求解器（http://lpsolve.sourceforge.net/5.5/index.htm）。链接的是python2.7。我发现了以下内容：https://github.com/chandu-atina/lp_solve_python_3x但它也不起作用。尝试了两种方法。我真的不知道如何让这个lp嫒解算器在UbuntuPython3.6上工作。有没有像下面这样的东西：https://www.lfd.uci.edu/~gohlke/pythonlibs/#lp_solve但是对于Ubuntu？在

也找到了这个，它起作用了：https://anaconda.org/snorfalorpagus/lpsolve 但我不能导入lpsolve。（以下是链接导入lpsolve的问题：Conda installation of lpsolve）

编辑1:

以下是我要采取的步骤：

mkdir -p /tmp/lp_solve && cd /tmp/lp_solve

wget -O ./lp_solve.tar.gz http://sourceforge.net/projects/lpsolve/files/lpsolve/5.5.2.0/lp_solve_5.5.2.0_source.tar.gz/download

tar -xf lp_solve.tar.gz

DOWNLOAD THE REPO FROM GITHUB  (https://github.com/chandu-atina/lp_solve_python_3x )

mkdir -p /tmp/lp_solve/lp_solve_5.5/extra/

//创建Python目录！只需确保origin是extra/Python

在sh ccc上，.h文件中有大量语法错误。 这里：

如何让lpsolve在raspbian上使用python 3.5.3：

从存储库安装

apt-get install lp-solve # for shared object file (liblpsolve55.so)
apt-get install liblpsolve55-dev # for header files (e.g. lp_lib.h)

从sourceforge（https://sourceforge.net/projects/lpsolve/files/lpsolve/5.5.2.5/lp_solve_5.5.2.5_Python_source.tar.gz/download）获取Python源代码。在

提取tar文件

通过运行启动安装

bash build.sh

在我的例子中，源文件有一些与python3无关的问题。在

1. 找不到lp_lib.h。通过将“/usr/include/lpsolve”添加到设置.py在
2. hash.c中定义的函数的多个定义错误。通过从要编译和链接的文件中删除“hash.c”文件来解决设置.py. 在
3. 未定义的参考符号。通过在库中添加“colamd”来解决此问题设置.py在

Python3相关问题：

1. 打印。。。已更改为打印（…）。更新时间设置.py在
2. PyString已更改为PyUnicode/PyBytes，PyInt更改为PyLong（https://docs.python.org/3/howto/cporting.html）。在pythonmod.c中更新
3. 初始化模块函数已更改（https://docs.python.org/2.3/whatsnew/node20.html、Difference between PyMODINIT_FUNC and PyModule_Create和https://docs.python.org/3/c-api/module.html）。在pythonmod.c中更新

在设置.py差异

验证安装是否如lpsolve（http://lpsolve.sourceforge.net/5.5/Python.htm#Installation）文档中所示工作

>>> from lpsolve55 import *
>>> lpsolve()
