pin

v0.19.0

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.

When a lockfile is in use, matching records will be migrated to the newly pinned specification. v0.60.0

The lockfile of the configuration file being modified is always kept in sync, even when another configuration file (like an environment configuration) takes precedence for that tool. v0.61.0

Arguments​

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

Options​

  • --resolve - Resolve the version to a fully-qualified semantic version before pinning.
  • --to v0.41.0 - Location of .prototools to update. Supports global, local, and user.
  • --tool-native v0.55.0 - 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.
