Which node.js version? Should be latest LTS, right now 10.15.0

Try to run yarn install before running other commands

[panique]

this also happens AFTER running npm install/ yarn install

@pkarw Got same error. Here's how I fixed it:

1. In webpack.base.config.ts change these to correct paths:

const translationPreprocessor = require('@vue-storefront/core/i18n/scripts/translation.preprocessor.js')
translationPreprocessor(
  [path.resolve(__dirname, '../../core/i18n/resource/i18n/'), path.resolve(__dirname, themeResources + '/i18n/')],
  config
)

2. Make require('@vue-storefront/...') work by using solution 0 here:
   https://gist.github.com/branneman/8048520
   in package.json add

  "dependencies": {
...
    "module-alias": "2.x.x",
...
  },
...

  "_moduleAliases": {
    "@vue-storefront": "./"
  },

In webpack.base.config.ts (and maybe others) add

require('module-alias/register')

Thanks, do You think it's a general solution that should be provided as a PR to the core?

@panique @fancydev18 @shelly28 could you please provide steps of a minimal reproduction including information about code, yarn and node version you are using?

[fancydev18]

Actually, I've used npm instead of yarn. That's why it doesn't work, as it doesn't support "workspaces". I've commented what I learned here: https://gist.github.com/branneman/8048520

The simplest solution would be to keep using yarn for now, until npm supports workspaces too.
"module-alias" solution would add extra complexity.

Feel free to close this. At least others trying npm would know why it doesn't work.
Thanks for looking into it.

[fancydev18]

Looks like workspaces are planned for npm too: https://blog.npmjs.org/post/173239798780/beyond-npm6-the-future-of-the-npm-cli

Thanks for sharing the solution with us 👍
