Or-tools: Installation issue OR-tools in windows

[BhagyaAmarasekara]

Hi,

I'm trying to install or-tools in windows with pip (pip install ortools). I'm using windows 8 with 64-bit system and python version is 3.6.2. I'm getting the following error,

Collecting ortools
Could not find a version that satisfies the requirement ortools (from versions: )
No matching distribution found for ortools

Can someone please help?

Most likely pip is too old.

Can you check its version?

Attempted to install 5.1.4045 on Linux, it worked great! Following the installation docs, unzipped python examples, ran make install, done. Version 6.1 didn't work, this information might help you.

[lperron]

you need to upgrade pip.

pip install --upgrade pip

to get a later version.

In my case, pip version is the latest one, pip 9.0.1.

[teocomi]

Same issue here, I managed to install it by downloading the pip exe installer and running it as admin.

@teocomi
Do you have a 32bits (x86) or 64bits (x86_64) version of windows ?
Which version of python did you use with pip (i.e. pip --version) ?

[teocomi]

@Mizux win 10 64bit, pip 9.0.1, python 2.7.14/3.6.4.
But I have to correct myself, I reinstalled python and then pip install also worked fine, not sure why.

[msramalho]

After wasting too much time on this, here's a likely solution:

Install python 64bit!!

ortools only works on 64bit, I had the 32bit (unknowingly) and I always got the same error:

Collecting ortools
Could not find a version that satisfies the requirement ortools (from versions: )
No matching distribution found for ortools

[Mizux]

You can test your python installation using:
python -c "import platform; print(platform.architecture())" then you can install ortools using:
python -m pip install ortools (I already see system where python and pip didn't point to the same dist-package...)

note: you may use python3 or python3.6 if you have installed recent version of python on a "old" system...
note2: you can use python -m pip --version to get the site package location...
