GLPK installation error

[Omid Alizadeh Mousavi]

Hi,

I have Python3.4 installed on Windows 10, 64-bit. I have installed PuLP on my machine successfully. I have tried to install GLPK but when I run "setup.py install" I get the following error. What might be the solution?

Thanks,

C:\Users\NB_DEPsys_1\Downloads\glpk-0.3>setup.py install

'which' is not recognized as an internal or external command,

operable program or batch file.

running install

running build

running build_ext

so this is a question about how to install glpk in windows, sorry I am not sure how to do that.

But pulp does come bundled with the cbc solver (the default) which is generally faster.
