The 2.1.2 release on NPM includes a reference to a developer-local directory (and doesn't correspond to the Github tag) about node-jxa HOT 2 OPEN

I experienced the same. Installing with npm leads to the 'deleteme.scpt' error you mentioned, and like you, it points to the developer's local user path. Copying the contents of GitHub's node-jxa.js over the top of the installation's script of the same name fixed it, but that shouldn't be necessary obviously.

You can use npm as it is by changing the package.json's dependencies as shown below.

(Because github's source code is imported as is.)

  "dependencies": {
    ...
    "node-jxa": "github:johnelm/node-jxa#v2.1.2"
    ...
  },
