[peter-jerry-ye]

Steps to reproduce:

• mkdir theia-app
• cd theia-app
• yo theia-extension and choose Hello World with the default name
• yarn build:electron
• yarn start:electron
• yarn build:browser
• yarn start:browser

Then the error comes up:

/Users/ye/Documents/theia-app/browser-app/lib/backend/vendors-node_modules_drivelist_build_Release_drivelist_node-node_modules_stroncium_procfs_lib-bd225a.js:16
  throw new Error('node-loader:\n' + error);
  ^

I can reproduce this. @sdirix Could you check whether we do no clean something correctly?

[sdirix]

We need to declare the cacheRoot so that this works out of the box. I'll open a PR.

@peter-jerry-ye see here on how to fix the issue for you locally. For the fix to take effect you should delete the node_modules as well as any .browser_modules directories you may currently have.

I confirm it fixes the issue if we build then start. However it seems that yarn watch can still cause issue.

You are correct. This will be fixed with https://github.com/eclipse-theia/generator-theia-extension/pull/178

@peter-jerry-ye Could you maybe verify the new version on mater with the fixes whether everything works now for you? If you clone this repo and then npm link you can test the updated version.

Thanks!

Looks good to me.
