TypeScript compile error due to typings

[hermanfransen]

I'm using typescript 1.7.5, typings 0.6.9 and angular 2.0.0-beta.0.

How can I get rid of the typescript compile error messages Duplicate identifier due to typings definition files?

The Duplicate identifier error occurs in the definition files of the following directories:

node_modules/angular2/typings/es6-shim/es6-shim.d.ts
node_modules/angular2/typings/jasmine/jasmine.d.ts
node_modules/angular2/typings/zone/zone.d.ts
typings/browser/ambient/es6-promise/es6-promise.d.ts
typings/browser/ambient/es6-shim/es6-shim.d.ts
typings/browser/ambient/jasmine/jasmine.d.ts
typings/browser/ambient/karma/karma.d.ts
typings/browser/ambient/zone.js/zone.js.d.ts

What's the compiler doing in node_modules/angular2 directory since I excluded it in tsconfig.json?

I also posted this question on StackOverflow

tsconfig.json

{
    "compilerOptions": {
        "target": "es5",
        "module": "system",
        "moduleResolution": "node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false
    },
    "exclude": [
        "node_modules",
        "typings/main",
        "typings/main.d.ts"
    ]
}

They are gone if I change the exclude part of tsconfig.json:

"exclude": [
    "node_modules",
    "typings"
]

But then after adding the following I get again the same Duplicate identifier compile errors:

/// <reference path="../../typings/browser.d.ts" />

typings.json

  "name": "example-mean-app-client",
  "dependencies": {},
  "devDependencies": {},

Your typings in node_modules/angular2/typings are <reference>d somewhere in your code.

Same problem here with typings 0.6.9, tsc.exe 1.8.2, launched in Visual Studio from MSBuild.exe through the TypeScript 1.8.4 for Visual Studio 2015 extension ("Compile TypeScript on build").
If my exclude section looks like this :

"exclude": [
    "node_modules",
    "wwwroot",
    "typings"
  ]

... then the compilation fails because the TypeScript compiler "Cannot find name", which seems right enough.

But if I selectively exclude all the subcontent of the same typings directory :

"exclude": [
    "node_modules",
    "wwwroot",
    "typings/browser",
    "typings/main",
    "typings/browser.d.ts",
    "typings/main.d.ts"
  ]

... then I get hundreds of Duplicate identifier errors.

Same thing with this exclude section (just with twice as many errors) :

"exclude": [
    "node_modules",
    "wwwroot",
    "typings/main",
    "typings/main.d.ts"
  ]

But with this last configuration, the build succeeds with the tsc 1.8.7 node module.

Edit: And the only s are in main.d.ts and browser.d.ts.

Edit: Deleting either the main.d.ts or the browser.d.ts file, along with its associated folder, "solves" the problem until the next typings install.

@rendmath, the issue you describe sounds a lot like #7198. file names in the exclude were not correctly excluded. can you try TS 1.8.5 (https://github.com/Microsoft/TypeScript/releases/tag/v1.8.7) and see if it does address the issue?

[rendmath]

Yes, it absolutely solves my problem.

The TypeScript 1.8.6 for Visual Studio 2015 extension doesn't show up in the Visual Studio Gallery, which led me to think that I had the latest version. That was wrong.

Thank you very much for you help.

[mhegazy]

thanks for that. it should show up shortly.

As described above, and to clarify: you need to either exclude {browser,main} that you don't need, or include (files) {browser.d.ts,main.d.ts} that you need:

{
  "exclude": [ "typings/browser", "typings/browser.d.ts" ]
}
// or
{
  "files": [ "typings/main.d.ts" ]
}

Referencing the issue on typings:
typings/typings#151 (comment)

This behavior will change soon.

[hermanfransen]

I was not aware there were duplicate typings in "node_modules/angular2/typing" and "typings" directory. Deleting duplicate typings solved my problem

tsd install es6-shim solves this issue without changing anything in the code base
