Error while building

[pantonis]

Short description of the problem:

Whenever I run ionic build android I get following error

ngc error: Error: Error Cannot write file '.tmp/app/app.component.d.ts' because it would overwrite input file.
Error Cannot write file 'C:/GIT/TestProj/.tmp/domain/ListingModel.d.ts' because it would overwrite input file.
and a bunch of similar errors

What behavior are you expecting?

Steps to reproduce:
1.
2.
3.

Which @ionic/app-scripts version are you using?
"@ionic/app-scripts": "latest",

@pantonis,

What happens if you delete the .tmp directory and try again? Run npm run build and see what the output is.

Thanks,
Dan

[pantonis]

@danbucholtz
I deleted the .tmp folder still the problem exists. What I found out though is that in each page folder I had the following structure

|src/
|-page/
|---home/
|-----home.html
|-----home.scss
|-----home.ts
|-----home.d.ts

note the d.ts file.

Once I deleted this d.ts file and all other d.ts files from pages the problem went away.

I am using VS2015 community edition.

Why it produces these?

[danbucholtz]

Ahhh, I think it because it is compiling code on save. We don't support that functionality and it should be disabled in the tsconfig.json file. Try disabling that or using VS Code to see if that resolves it.

Thanks,
Dan

[danbucholtz]

@pantonis,

I'm going to close this issue, but please let me know how everything is going and if there's anything else we can help get squared away with visual studio.

Thanks,
Dan

[pantonis]

I abandoned VS for VS code. everything works smoothly now.

Thanks

Mind letting us know? https://github.com/driftyco/ionic-cli/issues

In tsconfig.json compileOnSave = False;
I'm using VS Code.

PS... I had Installed Node, Ionic, Cordova all them lastest version.

[danbucholtz]

@aneudysamparo,

Can you paste your tsconfig.json in here? I think this issue is fixed in a release we have planned for today.

Thanks,
Dan

[aneudysamparo]

Hello @danbucholtz ,
Here my tsconfig.json
{ "compilerOptions": { "allowSyntheticDefaultImports": true, "declaration": true, "emitDecoratorMetadata": true, "experimentalDecorators": true, "lib": [ "dom", "es2015" ], "module": "es2015", "moduleResolution": "node", "target": "es5" }, "include": [ "src/**/*.ts" ], "exclude": [ "node_modules" ], "compileOnSave": false, "atom": { "rewriteTsconfig": false } }

[danbucholtz]

@aneudysamparo, we are pushing out a fix for this shortly. In the meantime, you can remove include from the tsconfig, but we will want to add that back in in a few hours.

Thanks,
Dan

[nyluje]

@danbucholtz , I also get the issue (and opened a StackOverflow ) my version is:
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

My tsconfig.json looks like that (no "include" and "compileOnSave:false"):

{
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "declaration": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [
      "dom",
      "es2015"
    ],
    "module": "es2015",
    "moduleResolution": "node",
    "target": "es5"
  },
  "exclude": [
    "node_modules"
  ],
  "compileOnSave": false,
  "atom": {
    "rewriteTsconfig": false
  }
}

[RoyBkker]

Same problem here!

[danbucholtz]

@RoyBkker, set declaration to false.

Thanks,
Dan
