## Creating the launch script
Pants is invoked via a launch script named `
./pants` , saved at the root of the repository. This script will install Pants and handle upgrades.
First, set up a minimal `
pants.toml` config file to instruct the script to download the latest 2.13 release:
Then, download the script:
Now, run this to bootstrap Pants and to verify the version it installs:
./pants` to version control
You should check the `
./pants` script into your repo so that all users can easily run Pants.
./pants` script will automatically install and use the Pants version specified in `
pants.toml`, so upgrading Pants is as simple as editing `
pants_version` in that file.
## Running Pants from unreleased builds
To use an unreleased build of Pants from the [pantsbuild/pants](🔗) main branch, locate the main branch SHA, set PANTS_SHA=<SHA> in the environment, and run `
./pants` as usual:
## Building Pants from sources
We currently distribute Pants for Linux (x86_64) and macOS.
If you need to run Pants on some other platform, such as Linux on ARM or Alpine Linux, you can try building it yourself by checking out the [Pants repo](🔗), and running `
./pants package src/python/pants:pants-packaged` to build a wheel.
