nenv pin tsc latest

undo

nenv unpin rome nenv unpin tsc ```

List nodejs versions

sh nenv list-versions

Version detection

The node version nenv uses is controlled by

1. The engines.node config field in the package.json which is parsed as a semver requirement. json { "name": "my project", "engines": { "node": "18" } }

2. The .node-version file in the current or parent directories which contains the version string. 19.4.0

3. The NODE_VERSION environment variable.

4. The default version set with nenv default.
