python - 如何为 python 3.6 安装 lpsolve？

Question

因此，我正在使用 python 3.6 运行时创建一个 Docker 容器。我需要用于 python 的 UX64 版本的 lp_solver ( http://lpsolve.sourceforge.net/5.5/index.htm )。链接的是python 2.7。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_solver 在 Ubuntu Python 3.6 上工作。是否有类似以下内容:https://www.lfd.uci.edu/~gohlke/pythonlibs/#lp_solve但是对于 Ubuntu？

还发现了这个，它起作用了:https://anaconda.org/snorfalorpagus/lpsolve 但我无法导入 lpsolve。 (这里是导入 lpsolve 的链接问题:Conda installation of lpsolve)

编辑 1:

以下是我采取的步骤:

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!只要确保 origin 是 extra/Python

cp -R extra/Python_that_is_downloaded  /tmp/lp_solve/lp_solve_5.5/extra/ 

cd /tmp/lp_solve/lp_solve_5.5/lpsolve55

chmod a+x ccc

sh ccc

在 sh ccc 上，我在 .h 文件中遇到大量语法错误。 这里:

user@user-box:/tmp/lp_solve/lp_solve_5.5/lpsolve55$ sh ccc

对不起，当我在代码中附上代码片段时，它在这里给了我错误。

我如何让 lpsolve 在 raspbian 上与 python 3.5.3 一起工作:

从仓库安装

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。

解压tar文件

tar -xzf lp_solve_5.5.2.5_Python_source.tar.gz
cd lp_solve_5.5/extra/Python

运行开始安装

bash build.sh

在我的案例中，源文件有一些与 python3 无关的问题。

1. lp_lib.h 无法找到。通过将 '/usr/include/lpsolve' 添加到 setup.py 中的 include_dirs 解决
2. hash.c 中定义的函数的多个定义错误。通过从要在 setup.py 中编译和链接的文件中删除“hash.c”文件来解决。
3. 未定义的引用符号。通过将“colamd”添加到 setup.py 中的库解决

Python3 相关问题:

1. print ... 已更改为 print(...)。在 setup.py 中更新
2. PyString 已更改为 PyUnicode/PyBytes，PyInt 已更改为 PyLong (https://docs.python.org/3/howto/cporting.html)。在 pythonmod.c 中更新
3. Init 模块功能已更改(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

验证安装是否按照 lpsolve ( http://lpsolve.sourceforge.net/5.5/Python.htm#Installation ) 文档中的指示工作

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