Node "Error: Cannot find module 'node:process'" when using global fastify-cli (mac)

I'm setting up a new mac dev machine, and have gotten node, npm, and nvm installed. All seems fine within a single project directory. However, when trying to install and use fastify-cli, I'm receiving an error:

internal/modules/cjs/loader.js:892
  throw err;
  ^

Error: Cannot find module 'node:process'

}

Steps to reproduce:

  1. $ npm install --global fastify-cli (succeeds)
  2. $ fastify generate myproject (also produces above error)
  3. $ fastify (also produces above error)

This likely doesn't have much to do with fastify. It seems to me that the global package is not finding Node for some reason, but I may be wrong.

  • I'm using zshell
  • I've got xcode installed
  • I've upgraded the version of node i'm using
  • I'm able to start a fastify app from the app directory directly/without using the generator

Any thoughts?

Solution

  • I fixed the error following the answer in this GitHub issue reply

    node internal syntax (e.g.: node:<core_module_name>) is not supported by Node.js 14.16.0

    The CLI needs node version >= 14.18

    Steps:

    1. Upgrade node using nvm to 14.18.0 (the last lts in 14.x).
    2. Set default version 14.18.0 or above.
