This script can be used to build @actions/setup-python when it was
installed as a dependency in another action.
Add dependency:
`npm install actions/setup-python#v2`
Automatically build on install:
```
"scripts": {
"postinstall": "npm run build-npm --prefix node_modules/setup-python"
}
```
Install depending action as usual:
`npm ci` or `npm install`
No further steps necessary, @actions/setup-python is built automatically
in the "postinstall" step of installation.
This pull-request improves `setup-python` action to add ability to download specific version of Python on flight if it is not available by default.
**Details:**
`setup-python` action will download and install specific Python version from GitHub releases ([actions/python-versions](https://github.com/actions/python-versions/releases)) in case the version is not found in the local cache. All versions of Python available for installation are published in [actions/python-versions](https://github.com/actions/python-versions) repository.
All available versions are listed in the [version-manifest.json](https://github.com/actions/python-versions/blob/master/versions-manifest.json) file.
**Installation time:**
- Ubuntu / macOS: 10-20 seconds
- Windows: ~ 1 minute (mostly related to fact that we use MSI installer for Python on Windows)
