[marcoarruda]

Describe the bug

After running the migration cli wizard npx sb upgrade

Steps to reproduce the behavior

1. Go to your project root folder (that runs storybook 6.5)
2. Run the migration commend npx sb upgrade
3. Answer the questions accordingly to your project
4. Run the serve and see the error

Error: Cannot find module '@storybook/core/server'

Expected behavior

To run the server properly

Screenshots and/or logs

I found a similar issue and a PR to fix the same (or very close to) issue for version 6.5

Environment

• OS: ARM M1 silicon
• Node.js version: v16.17.1
• NPM version: 8.15.0

Additional context

Can you please start over and try running npx sb@latest upgrade? npx is notorious for using cached versions, which can cause lots of problems for Storybook.

I also tried to migrate using Storybook's auto migration tool and encountered this issue:

➜ yarn storybook
yarn run v1.22.19
$ vue-cli-service storybook:serve -p 6006 -c config/storybook

@sybers that sounds like a different issue. Could you please open a new issue (ideally with a reproduction), and mention me on it so I see it?

But if I had to guess, I'd say vue-cli-plugin-storybook might not be compatible with 7.0. I would start there by checking that.

doh, I didn't realize this was the repo for the plugin. 😵
