Create-react-app: Startup error

[rkosenko]

Description

Last versions (from 1.0.0) cannot start and show the following error:

webpack.validateSchema is not a function
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] start-js: `react-scripts start`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] start-js script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

And the following is in the log:

Expected behavior

Everything works like in the previous version (0.9.5).

Actual behavior

It doesn't work. rm -rf node_modules && npm install doesn't help. Rollback to the version 0.9.5 helps.
Haven't tried to rollback webpack-dev-server to the first version.

Environment

Run these commands in the project folder and fill in their results:

1. npm ls react-scripts (if you haven’t ejected):
   [email protected] /home/user/src/project/frontend
   └── [email protected]
2. node -v:
   v7.10.0
3. npm -v:
   4.6.1

Then, specify:

1. Operating system:
   Linux

Please provide a full project reproducing this.
Or at least your package.json.

Can you provide a project reliably reproducing this? Have you tried to use a different npm version (or Yarn)? Have you tried npm cache clear before running npm install?

I was seeing the same issue and the problem was #2352. Storybook is holding on to an old version of webpack and that's the one that create-react-app attempts to use. I think there was a note about that in one of the releases but I forgot to remove the dependency before I tried upgrading.

[rkosenko]

react-scripts v1.0.10, node v8.2.1, npm v5.3.0 - still the same. Even after npm cache --force clear. With Yarn it works fine.
