IONIC 2 Build error: “ngc: Error: Error Cannot write file …[myProject]/.tmp/[some folder]/*.d.ts”

I get build error when I launch a CLI: "ionic build android"

The error applies to several file, all applying the same pattern: "ngc: Error: Error Cannot write file '[myProjectName]/.tmp/[some more folder + a file with '.d.ts' extension]' because it would overwrite input file."

Ionic version:

  • Cordova CLI: 6.3.1
  • Ionic Framework Version: 2.0.0-rc.0
  • Ionic CLI Version: 2.1.0
  • Ionic App Lib Version: 2.1.0-beta.1
  • OS: Windows 10
  • Node Version: v6.7.0

I've tried to launch a CLI: "npm install", and then CLI: "ionic add/rm/add platform android". Relaunched the build and still get the same error.

Any idea about what is going on? What's the matter with the ".tmp" folder?

Some update: The issue happens to have an existing thread here . At some point in the thread, it suggests to delete the "*.d.ts" files. It does the trick but it means that operation might have to be done manually again in the future, so a better solution are still pending.

I was having the same issue.

Change your tsconfig.json to have 

"compilerOptions": {
    "declaration": false,
 ...
