(beta.11-webpack) Promise - Corresponding file is not included in tsconfig.json

[eshell]

Please provide us with the following information:

1. OS? Windows 7, 8 or 10. Linux (which distribution). Mac OSX (Yosemite? El Capitan?)
   ubuntu 16.04
2. Versions. Please run ng --version. If there's nothing outputted, please run
   in a Terminal: node --version and paste the result here:

Could not start watchman; falling back to NodeWatcher for file system events.

angular-cli: 1.0.0-beta.11-webpack
node: 5.11.1
os: linux x64

1. Repro steps. Was this an app that wasn't created using the CLI? What change did you
   do on your code? etc.

the app was build with angular-cli@beta-10. I followed upgrade instructions and Promises no longer worked, along with styles. 

1. The log given by the failure. Normally this include a stack trace and some
   more information.

No errors client side. Just in webstorm.

1. Mention any other details that might be useful.

ran `npm i @types/es6-promise` and tried adding "es6-promise" to "types":["jasmine"] array and that didn't work. Makes my app unusable.

Thanks! We'll be in touch soon.

UPDATE
Promises still compile and work, but it shows all the errors in webstorm. Not sure if I should just suppress statements with Promise types and .then() statements or not.

[eshell]

After doing the same thing over again a few times I managed to get it to work.

npm i @types/es6-promise
then added es6-promise to types in tsconfig.json

for some reason those steps didn't work the first time, now it does.

[eshell]

Now i get this after ng build -prod

tsconfig.json

{
  "compilerOptions": {
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": ["es6", "dom"],
    "mapRoot": "./",
    "module": "es6",
    "moduleResolution": "node",
    "outDir": "../dist/out-tsc",
    "sourceMap": true,
    "target": "es5",
    "typeRoots": [
      "../node_modules/@types"
    ],
    "types": [
      "jasmine","es6-promise"
    ]
  }
}

It still compiles and works however. It seems to be complaining about declare class Promise and declare namespace Promise is all I can make of it.

The lib entry on tsconfig takes care of providing Promise to the Typescript compiler.

The problem here is that your editor does not yet support TS2.0 properties such as lib, typeRoots and types I believe. VS Code also has that problem.

It's an editor problem though, not a CLI problem... maybe you can update the version of typescript used in Webstorm. Can't help you much there since I don't use it myself.

[eshell]

I re-updated the cli and used typescript 2.0 libs in my editor. it still gives errors, so ill just suppress them for now.

[Codermar]

Having the same issue here. How did you suppress the errors? Is there a permanent solution yet?

[EugenIvanou]

I have the same issue, even after update to webstorm 2016.2.2 from 2016.2.1. TypeScript version 1.8 in the "Languages & Frameworks" settings.

[filipesilva]

You have to update the version of Typescript used in Webstorm to 2.0.0. Check Webstorm documentation on how to do this.

[blackat]

@EugenIvanou @Codermar @eshell I guess Webstorm is pretty similar to Idea, I am using 2016.2 version and I have installed TypeScript 2.0.2 as global package, then I configure Idea to use that version and not the bundled one.

I guess all the issues comes from, as pointed out from @filipesilva, the TypeScript version you use. Idea/Webstorm should even mark some issue in the tsconfig.json about some unrecognized properties.

@filipesilva said that lib properties has to provide Promises definition to compiler, indeed from tsconfig schema

"lib": {
  "description": "Specify library file to be included in the compilation. Requires TypeScript version 2.0 or later.",
  "type": "array",
  "items": {
    "type": "string",
    "enum": [
      "es5",
      "es6",
      "es2015",
      "es7",
      "es2016",
      "es2017",
      "dom",
      "webworker",
      "scripthost",
      "es2015.core",
      "es2015.collection",
      "es2015.generator",
      "es2015.iterable",
      "es2015.promise",
      "es2015.proxy",
      "es2015.reflect",
      "es2015.symbol",
      "es2015.symbol.wellknown",
      "es2016.array.include",
      "es2017.object",
      "es2017.sharedmemory"
    ]
  }
}

I have just generated a project with angular-cli, I had your same issue that disappeared once TypeScript 2.0.2 has been configured, if I install @types/es6-promise I get duplicate identifier error as @eshell.

My current platform version:

angular-cli: 1.0.0-beta.11-webpack.8
node: 5.4.1
os: darwin x64

Under OS X global packages are installed in /usr/local/lib/node_modules.

Hope it helps 😉

@blackat how did you do that? I am still getting the error. I have configured the typescript version in the webstorm, what else steps do I need? update the tsconfig file?

[blackat]

@ljieyao Have you tried to remove es6-promise from

"types": [ "jasmine","es6-promise" ]

?
