throw new Error(${file} does not exist);

[ajmeese7]

No matter how I configure this project, the only output I get when I run it is this:

D:\_Programming\aaronmeese.com\common\scripts\package-inherit-cli.js:36656
                    throw new Error(`${file} does not exist`);
                    ^

Error: undefined does not exist

Any more helpful documentation would be appreciated.

The problem is that it's using an old version of workspace-tools that doesn't understand native npm workspaces yet.

I was able to get it working as follows:

1. Clone this project
2. Update package.json to the latest workspace-tools (currently 0.23.3)
3. npm run build
4. Copy the new build/package-inherit-cli.js into your project
5. Make sure your base directory is actually registered as a package in the workspace config
6. Reference an inherited json as a module path rather than a file path...it is incredibly picky here and won't help if you get it wrong

So,

// ./packages/base/package.json
{"name": "@my-scope/base"}

// ./packages/base/package.foo.json
{
  "scripts": {
    "foo": "echo foo"
  }
}

// ./packages/child/package.json
{
  ...
  "scripts": {}, // necessary because of issue #1
  "inherits": [
    "@my-scope/base/package.foo.json"
  ]
  ...
}

// ./package.json
{
  "scripts": {
    "preinstall": "node ./packages/base/package-inherit-cli.js update"
  },
  "workspaces": [
    "packages/base",
    "packages/child"
  ]
}

Cool idea, but it needs some maintenance.
