Duplicate Identifier when building

[x ] bug report
[ ] feature request
[ ] question about the decisions made in the repository

Hi after updating, I keep getting these kind of duplicates in my logs. I've tried to find out if I might be building something double or such. But I can't find anything, before pulling everything was fine (I used to be on angular.8 beta now it's the 10 version, I saw this at 9 too so I reverted.

What is the current behavior?
It works just fine in dev, but prod can't be build and the logs are stuffed with above error.
Please tell us about your environment:
Latest Master properties building from a macbook pro with mostly everything updated to recent.

Confirming issue - I cloned and installed a copy of this project yesterday and got the same errors (though different typings files were colliding for me, attaching screenshots)

Nothing worked until I reverted to angular 2 beta.8 but now have no apparent errors.

Just remove typings folder and do 'npm install'.

@alvipeo

@alvipeo I removed the typings folder and ran npm install with no success.

Here's my package.js (beta 11) which works (with moment.js and crypto-js as an extra, you can remove them):

@alvipeo

I installed latest angular2-webpack-starter and started it with no modifications. I also tried the package.json posted above by @alvipeo.

I get the following:

[default] C:/Develop/toolbox-client/node_modules/zone.js/dist/zone.js.d.ts (127,5):
    Duplicate identifier 'parent'.
[default] C:/Develop/toolbox-client/node_modules/zone.js/dist/zone.js.d.ts (131,5):
    Duplicate identifier 'name'.
[default] C:/Develop/toolbox-client/node_modules/zone.js/dist/zone.js.d.ts (219,5):
    Duplicate identifier 'current'.
[default] C:/Develop/toolbox-client/node_modules/zone.js/dist/zone.js.d.ts (223,5):
    Duplicate identifier 'currentTask'.
[default] C:/Develop/toolbox-client/node_modules/zone.js/dist/zone.js.d.ts (234,5):
    Duplicate identifier 'name'.
[default] C:/Develop/toolbox-client/node_modules/zone.js/dist/zone.js.d.ts (238,5):
    Duplicate identifier 'properties'.

.......etc.......

Also

[default] C:/Develop/toolbox-client/src/polyfills.ts (11,8):
    Exported external package typings file 'C:/Develop/toolbox-client/node_modules/zone.js/dist/zone.js.d.ts' is not a module. Please contact the package author to update the package definition.

If I get rid of zone.js from typings.json then I only get:

[default] C:/Develop/toolbox-client/src/polyfills.ts (11,8):
    Exported external package typings file 'C:/Develop/toolbox-client/node_modules/zone.js/dist/zone.js.d.ts' is not a module. Please contact the package author to update the package definition.

But I also get the following javascript error in the browser:

Uncaught TypeError: Cannot read property 'cancelTask' of undefined zone.js?e3a6:116

Will try above tomorrow. Happy to hear it's not just me

can you pull latest

Removing selenium-webdriver from typings.json, and redo typings did it for me..

I pulled latest, however now I get this "Uncaught TypeError: core_1.View is not a function." on startup, so nothing works anymore. npm start doesn't show errors though. Is that the issue with Material2 maybe?

@msegers

@msegers material2 should be commented out. They need to update their repo
related angular/components#213

Explains, I was using it already with angular 10, so now it's broken. That means that your pull should have resolved my problems since I don't see those around anymore.

what's the error?

ignore dist in tsconfig
4a4cd48

@gdi2290

@gdi2290 - I also added "typings" to the exclude:
tsconfig.json:

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