pin

import VersionLabel from '@site/src/components/Docs/VersionLabel';

The proto pin <tool> <version> command will pin a version (or alias) of a tool. This version will be used when attempting to detect a version.

$ proto pin go 1.20
$ proto pin python 3.14 --to=global
$ proto pin node lts --resolve
$ proto pin npm latest --resolve --tool-native

By default this will update the local ./.prototools file. Pass --to to customize the location, or use the --tool-native option to use a location unique to the tool.

Arguments

• <tool> - Type of tool.
• <version> - Version of tool.

Options

• --resolve - Resolve the version to a fully-qualified semantic version before pinning.
• --to - Location of .prototools to update. Supports global, local, and user. <VersionLabel version="0.41.0" />
• --tool-native - Pins the version in a tool specific location. Examples:
  • JavaScript tooling (Node, Bun, Deno, npm, pnpm, Yarn, etc)
    • Pins version in the devEngines field in the package.json file.
  • <VersionLabel version="0.55.0" />
