This guide gets you started with OR-Tools in Python with a simple working example.
Although these instructions might also work on other MacOS variants, we have only tested them on machines meeting the following requirements:
- MacOS 13.0.1 (Ventura) Intel 64-bit (x86_64)
- MacOS 13.0.1 (Ventura) M1 (arm64)
The following sections describe the prerequisites for installing OR-Tools.
To install the remaining prerequisites, we recommend first installing the "missing package manager for macOS" otherwise known as Homebrew. To do so, open a terminal window and enter:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
To verify that you’ve successfully installed brew:
You should see:
Homebrew 1.6.9-8-g25542d7 Homebrew/homebrew-core (git revision 0e0c84; last commit 2018-06-20)
You must have Python 3.6+ installed.
To install Python 3.6+, open a terminal window and enter:
brew install python
python3 -m pip install -U --user wheel six
Then verify your installation:
python3 -c "import platform; print(platform.architecture())"
python3 -m pip --version
Assuming the prerequisite software is installed on your MacOS, take the following steps:
python3 -m pip install -U --user ortools
Or, to install it system wide:
sudo python3 -m pip install -U ortools
To uninstall OR-Tools, issue the following commands:
python3 -m pip uninstall ortools
