Error: Cannot find module 'fork-ts-checker-webpack-plugin'

[aalibaabaa]

Description

We installed a demo project for jss react as described in the quickstart: https://jss.sitecore.com/docs/getting-started/quick-start

npm install -g @sitecore-jss/sitecore-jss-cli
jss create my-first-jss-app react
cd my-first-jss-app
jss start

This works without problems. But then we deleted the node_modules and re-installed it (as we always do e.g. for code reviews)

After doing that, starting the app again with npm start ends in this error:

path or pattern './sitecore/pipelines/**/*.patch.js' did not match any files.
internal/modules/cjs/loader.js:583
    throw err;
    ^

Error: Cannot find module 'fork-ts-checker-webpack-plugin'

Expected behavior

App should start by running npm start as it did after initial installation

Steps To Reproduce

1. Install quick start project (see description above)
2. Start project npm start -> app starts
3. Stopp app
4. Remove packages rm -rf node_modules package-lock.json
5. Re-install packages npm install
6. Start app npm start => error occurs

Possible Fix

Update react-scripts package to v2.1.4 (currently the latest stable version)

Your Environment

• Sitecore Version: 9.1
• JSS Version: 11.0.2
• Node.js: 10.7.0

I'm closing this one as described behaviour is no longer reproducible.
