Abbreviated runtimeVersion in launch.json not working

[wongjn]

Issue Type: Bug

$ nvm list
        v8.17.0
       v10.22.0
->     v12.22.1
       v14.17.0
        v16.3.0
…

launch.json:

{
  // Use IntelliSense to learn about possible attributes.

  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Jest",
      "program": "${workspaceRoot}/node_modules/.bin/jest",
      "args": ["--color"],
      "outputCapture": "std",
      "runtimeVersion": "16"
    }
  ]
}

Running this debug task fails with "Node.js version '16' cannot be found for 'nvm'":

However, if the value of runtimeVersion to a specific version I have installed ("runtimeVersion": "16.3.0" in this case), the debug task runs as expected.

I believe this is a bug since the Multi version support section of Node.js debugging documentation states that:

If you omit the minor and patch version and have, for example, "runtimeVersion": "14", then the most recent 14.x.y version installed on your system will be used.

So my understanding here is that 16.3.0 should be used in this setup and should not error.

You'll need to set your launch type to pwa-node for this to work. The old node type is redirected through the previous debugger, but only after it tries (and failed) to resolve that version number. This'll no longer be necessary when the old debugger (eventually) goes away entirely.

[connor4312]

Oh, yea, I see we recommend that in our docs. That needs to be updated.

[connor4312]

The old debuggers are being removed next month, so I will just assign this to that iteration since it'll be fixed at that point.

Fixed with microsoft/vscode-js-debug#1065
