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.

{
  "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.
