Python:为什么在MacOSX上导入glpk时会遇到此错误? [英] Python: Why am I encountering this error with importing glpk on MacOSX?
问题描述
我按照以下步骤操作,但遇到了第一个错误:
I followed these steps and got my first error:
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:
内swig/Makefile
Then I linked to the python by changing the Python version or let's say section:
inside swig/Makefile
已更改
PYVERS := $(shell pyversions -d)
到
PYVERS := "Python 2.7.6"
这是我的python版本
which is my python version
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:
Now when I run python test.py
inside the examples folder, it just crashes and says:
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/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: 从源代码构建并安装
I tried the following tutorials: Build and install from source
然后我尝试
有些事情是不对的,我错过了导致
Something is just not right, what step am I missing that is causing the
import glpk
失败了吗?
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.
I tried brew installation as well, no luck! I have included my Python path as well, still no help.
啊,最后我尝试了这个:
Ah and lastly I tried this:
import sys
sys.path.append('/Library/Python/2.7/site-packages/glpk/')
仍然没有运气!最后一步是答案
still no luck! Last step was inspiration from this answer
推荐答案
好,我试图重现您的问题并遇到相同的错误,
我设法通过将ply
的版本从 3.6 更改为 3.4 .
Ok, I tried to reproduce your problem and went through the same errors,
I managed to make it work by changing the version of ply
from 3.6 to 3.4.
请注意,我在glpk
库中遇到错误,必须将其降级为 4.43
Note that I had an error with the glpk
library and had to downgrade it to 4.43
