core-js modules not found when using load all stories glob

Describe the bug Multiple Can’t resolve ‘core-js/modules/’ errors, but only when using the .storybook/config.js to load all stories matching a glob method.

To Reproduce Steps to reproduce the behavior:

1. Fresh install of Angular 8
2. Fresh install of @storybook/angular following the guide at https://storybook.js.org/docs/guides/guide-angular/
3. Create config.js file (see below)
4. npm run storybook
5. Errors.

Expected behavior Storybook to load just like it does if I specify individual file import without trying to match /.stories.ts$/

Screenshots

Code snippets .storybook/config.js: `import { configure } from ‘@storybook/angular’; import requireContext from ‘require-context.macro’;

const req = requireContext(‘…/src/app/modules’, true, /.stories.ts$/);

function loadStories() { req.keys().forEach(filename => req(filename)); }

configure(loadStories, module);`

System:

• OS: Ubuntu via WSL on Windows 10
• Device: Dell Inspiron
• Browser: Chrome/Firefox latest for both
• Framework: Angular
• Addons: None
• Version: Storybook - ^5.1.3 Angular - ~8.0.0 core-js - ^2.5.4

Additional context I have tried upgrading core-js to 3, to various specific versions of 2… nothing seems to work. As long as I use the load all stories method, I get those errors.

This is fixed for me with storybook 5.1.5

Angular 8 dropped core-js as a dependency. You said

I have tried upgrading core-js to 3, to various specific versions of 2…

I did a fresh setup myself and it has worked - have you tried to follow the manual steps or have you used the CLI?

Can you try a fresh installation with

• npx @angular/cli new angular8-project
• cd angular8-project
• npx @storybook/cli init
• npm run storybook

Or try https://github.com/storybookjs/storybook/blob/next/MIGRATION.md#angular-7 but this was originally a fix for Angular 7 with core-js 3
