package.json failed to parse due to error SyntaxError

Note:

It works when I clear out the package.json and just leave {}. So something goofy is afoot with the json parser.

What is the expected behavior?

Dep installs

What do you see instead?

Error

Additional information

This is using workspaces. The most basic package as well:

{
  "name": "project",
  "private": true,
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "workspaces": [
    "packages/*",
    "apps/*"
  ],
  "keywords": [],
  "author": "",
  "license": "ISC"
}

The issue is with this bit:

    "testRegex": ".*\\.spec\\.ts$",
    "transform": {
      "^.+\\.(t|j)s$": "ts-jest"
    },

Removing this makes it work. I can't, because I need it (so I'll use npm for a bit longer). This is my punishment for being curious 😄

Here we are facing the same issue(v1.1.17). Definitely a bug, it might be about none standard properties like jest. In our case as workaround we remove jest, execute the install command then bring jest property back. @Jarred-Sumner can you please help us?

[RWOverdijk]

I solved it by going back to just using npm. Can I hand this issue over to someone who cares? Or should I just unsubscribe from the issue.
