Unhandled promise rejection (rejection id: 1): Error: Cannot find module '../cordova/platform_metadata'

When I attempt to build the project, I get the following error. I've upgraded, uninstalled, re-installed node, npm, cordova-cli, ionic. Any ideas?

$ cordova build android --verbose

Hello,
Should be fixed with version 1.7.1.

[jonathanwkelly]

@akofman the issue is not resolved after I remove the cordova-plugin-add-swift-support plugin, re-add, then attempt to build. The output is exactly the same.

Were you able to reproduce this issue?

[akofman]

I didn't try with ionic in particular but I didn't have any issue anymore on a pure Cordova project. Did you check the version of the plugin after you re-add it ? Also maybe you have to clear your package-lock.json before.
