"yarn prepare" failure in fresh clone

[parkerault]

After cloning and running yarn, yarn prepare throws the following error:

~/build/ahoopen-monorepo$ yarn prepare
yarn run v1.22.10
$ node ./configure-references.js
(node:30908) UnhandledPromiseRejectionWarning: SyntaxError: Unexpected token : in JSON at position 17

Done in 0.21s.

Running node ./configure-references.js works fine, although none of the packages have dependencies on other packages.

This is the output of yarn workspaces info --json, which looks fine to me so your guess is as good as mine:

{
  "@ahoopen/core": {
    "location": "packages/core",
    "workspaceDependencies": [],
    "mismatchedWorkspaceDependencies": []
  },
  "@ahoopen/utils": {
    "location": "packages/utils",
    "workspaceDependencies": [],
    "mismatchedWorkspaceDependencies": []
  },
  "@ahoopen/web": {
    "location": "packages/web",
    "workspaceDependencies": [],
    "mismatchedWorkspaceDependencies": []
  }
}

Is this repo up to date with the blog articles?

Edit: never mind, I see that the series of articles is not completed.

Hi @parkerault

It's important to have the latest version of yarn. And you don't have to run yarn prepare yourself. It will run automatically if you call yarn. The idea is, that when you add new dependencies to the mono repo this will run after the install. Thus keeping your TypeScript tsconfig up to date :)

If you have any questions, feel free to ask them.
