Ionic 2 build error (Cannot find module '../dist/build')

Question

I try to build an desktop app with Ionic 2 and Electron.

Therefore I followed the https://blog.couchbase.com/create-a-desktop-app-that-syncs-using-electron-pouchdb-ionic-2-and-couchbase/ tutorial

But with Ionic 2.1.12 and ionic-app-scripts 0.0.47 (I get the same error if I try it with ionic-app-scripts 1.1.4) I get the following error:

[17:19:44]  ionic-app-scripts 0.0.47 
[17:19:44]  ionic-app-script task: "build;" 
[17:19:44]  Error: Cannot find module '../dist/build;'

The detailed log file looks like:

Answer 1

I just hit the same error when I tried it, and it had a closer look at the statement Error: Cannot find module '../dist/build;'

notice the semicolon ?

Change the line in package.json to

"electron": "ionic-app-scripts build electron ."

Then it can find the task in @ionic and will perform the build
