如何在macOS Sierra 10.12.3上安装适用于Python 3.6的openbabel [英] How to Install openbabel for Python 3.6 on macOS Sierra 10.12.3

问题描述

我正在使用Python编写脚本来处理博士中的某些化学结构.我想为python安装openbabel库.我已尽力而为，但无法在Windows上安装它.我之前在

I am using Python for making a script to work with some chemical structures in my PhD. I want to install openbabel libraries for python. I tried my best but I could not install it on Windows. I posted a question earlier about installing it on Windows at How do I install openbabel for Python 3.6 in Windows 10? but could not find a solution. The solution installed the library but it does not work and could not connect to SWIG. No I am trying to install it on my office computer which is a mac for past 5 hours but I could not figure what is going on. I tried to install it from source code of Opnbabel and link it with python3 but it is making problem. If I use the following command:

cmake ../ -DPYTHON_BINDINGS=ON -DRUN_SWIG=ON

它成功地将其链接到我不想要的Python 2.7.当我尝试以下选项时，它会显示以下错误:

It successfully links it to Python 2.7 which I do not want. When I try the following options, it gives the error shown below:

cmake ../ -DPYTHON_EXECUTABLE=/usr/bin/python3 -DPYTHON_BINDINGS=ON -DRUN_SWIG=ON

OR

cmake ../ -DRUN_SWIG=ON -DPYTHON_EXECUTABLE=/usr/bin/python3 -DPYTHON_INCLUDE_DIR=/Library/Frameworks/Python.framework/Versions/3.5/include/python3.5m -DPYTHON_LIBRARY=/Library/Frameworks/Python.framework/Versions/3.5/lib/libpython3.5m.dylib -DPYTHON_BINDINGS=ON

在大量成功输出之后，最终会出现以下错误:

It gives the following error at the end after a lot of successful output:

-- Found PythonInterp: /usr/bin/python3.6 (found version "1.4") 
-- Found SWIG: /usr/local/bin/swig (found version "3.0.12") 
-- Found SWIG: /usr/local/bin/swig (found suitable version "3.0.12", minimum required is "2.0") 
-- Found PythonLibs: /usr/local/Cellar/python3/3.6.0/Frameworks/Python.framework/Versions/3.6/lib/libpython3.6m.dylib (found version "3.6.0")

我不确定为什么它检测到Python为v1.4 -- Found PythonInterp: /usr/bin/python3.6 (found version "1.4")而不是找到v.3.5. 我也尝试使用python 3.6进行所有过程，但发生相同的错误.我还使用从github获得的openbabel，据说在下面的帖子中使用了这些命令: http://forums.openbabel.org/OpenBabel-for-Python-3-td4659432.html 但是，它也不能正常工作. 请帮助我，因为我需要此模块来进行研究. 谢谢

I am not sure why It detects the Python as v1.4 -- Found PythonInterp: /usr/bin/python3.6 (found version "1.4") instead of finding v.3.5. I tried all the procedure with python 3.6 as well but the same errors occur. I am also using the openbabel obtained from github which was said to be working with these commands at the following post: http://forums.openbabel.org/OpenBabel-for-Python-3-td4659432.html But it doesn't work as well. Please help me as I require this module for my research. Thanks

推荐答案

我找到了解决方案.这是详细的解决方案:

I found the solution for that. Here is the detailed solution:

1. 从原始来源下载Open Babel( https://github.com/openbabel/openbabel )

将其提取并cd进入(openbabel-master)

Extract it and cd into it (openbabel-master)

创建一个目录"build"，并进入cd.

Make a directory "build" and cd into it.

运行以下命令:

cmake ../ -DPYTHON_EXECUTABLE=/Library/Frameworks/Python.framework/Versions/3.5/bin/python3 -DPYTHON_BINDINGS=ON -DRUN_SWIG=ON

在上面的命令中，-DPYTHON_EXECUTABLE"开关告诉它找到Python3解释器的路径.您可以在终端上通过which python3进行检查.

In the command above, the "-DPYTHON_EXECUTABLE" switch tells it the path where Python3 interpretor is found. You can check it by which python3 at a terminal.

make

make install

全部完成！ :)
