Cannot find module 'json-schema' #2012

danilobjr · 2020-05-12T07:02:50Z

Hello. I'm getting an error when trying to run a npm script on terminal. I got below code from TypeScript-Node-Starter repo from Microsoft. I just updated all packages to the latest version. Maybe something is not right with new versions or am I doing something wrong? Thanks in advance.

Repro

On terminal

yarn lint

lint script on package.json

  ...
  "lint": "tsc --noEmit && eslint \"**/*.{js,ts}\" --quiet --fix",
  ...

.eslintrc.js file. Simplified version of Microsoft one.

module.exports = {
  root: true,
  parser: "@typescript-eslint/parser",
  plugins: [
    '@typescript-eslint',
  ],
  "extends": [
    'plugin:@typescript-eslint/eslint-recommended',
  ],
}

Expected Result

Run without errors

Actual Result

Throws an exception

Additional Info

I just run this command in terminal yarn lint ---debug and got this:

Seems like a peer dependency issue somewhere. Manually installing json-schema resolves the problem.

LeoEatle · 2020-05-12T09:23:11Z

#2007

waiting for release

corno · 2020-05-12T09:28:36Z

I experience the same issue

marekdedic · 2020-05-12T10:05:09Z

Hi,
I started getting the same issue after upgrading to eslint 7.0.0... This is with @typescript-eslint/eslint-plugin 2.32.0

saadriazkhan · 2020-05-12T12:06:08Z

Try downgrading to
@typescript-eslint/parser@2.31.0
and
@typescript-eslint/eslint-plugin@2.31.0

Hope this helps.

AviVahl · 2020-05-12T12:17:29Z

This issue is a duplicate of #2009, which was fixed in master and in canary versions. We are all awaiting a release.

Unrelated to the json-schema error, is the fact that eslint@7 is not yet supported. This is tracked on #1550.

Both issues are pinned at the top of the issues list.

bradzacher · 2020-05-12T22:30:40Z

This has now been released to latest - 2.33.0
