Python：为什么在MacOSX上导入glpk时会遇到此错误？

我按照以下步骤操作,遇到了第一个错误：

wget http://www.dcc.fc.up.pt/~jpp/code/python-glpk/python-glpk_0.4.43.orig.tar.gz
tar -xzf python-glpk_0.4.43.orig.tar.gz
cd python-glpk-0.4.43/src/
sudo make install

我收到此错误：

make -C swig all
make[1]: pyversions: Command not found
gcc -Wall -c -fPIC glpkpi_wrap.c -DHAVE_CONFIG_H -I/usr/include/ -I/usr/lib//config
glpkpi_wrap.c:130:11: fatal error: 'Python.h' file not found
# include <Python.h>
          ^
1 error generated.
make[1]: *** [glpkpi_wrap.o] Error 1
make: *** [all] Error 2

然后我通过更改Python版本或下面的部分链接到python：
在swig / Makefile中

变了

PYVERS := $(shell pyversions -d)

至

PYVERS := "Python 2.7.6" 

这是我的python版本

make -C swig all
swig -python  glpkpi.i
./glpk.h:916: Warning 314: 'in' is a python keyword, renaming to '_in'
sed -i 's/:in /:_in /g' glpkpi.py
sed: 1: "glpkpi.py": extra characters at the end of g command
make[1]: *** [glpkpi.py] Error 1
make: *** [all] Error 2

现在,当我在示例文件夹中运行python test.py时,它只是崩溃并说：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/glpk/__init__.py", line 26, in <module>
    from glpk_parser import *
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/glpk/glpk_parser.py", line 352, in <module>
    yacc.yacc(write_tables=0, debug=0)
  File "/Library/Python/2.7/site-packages/ply/yacc.py", line 3244, in yacc
    read_signature = lr.read_table(tabmodule)
  File "/Library/Python/2.7/site-packages/ply/yacc.py", line 1967, in read_table
    if parsetab._tabversion != __tabversion__:
AttributeError: 'module' object has no attribute '_tabversion'

我尝试了以下教程：
Build and install from source

然后我尝试

Installing-Python-glpk Tutorial

只是不对,我错过了哪一步导致

import glpk

失败？

我也尝试了Brew安装,没有运气！我也包括了我的Python路径,仍然没有帮助.

啊,最后我尝试了这个：

import sys    

sys.path.append('/Library/Python/2.7/site-packages/glpk/')

还是没有运气！最后一步是来自这个answer的灵感

解决方法:

好的,我尝试重现您的问题,并遇到了相同的错误,
我设法通过将层板的版本从3.6更改为3.4使其起作用.

请注意,我的glpk库出现错误,必须将其降级为4.43
