typescript errors

[paul23-git]

I'm submitting a bug report

• Aurelia Skeleton Version
  skeleton-typescript

• Framework Version:
  1.1.2

Please tell us about your environment:

• Operating System:
  Windows 10

• Node Version:
  8.9.0

• NPM Version:
  5.5.1

• **JSPM **
  JSPM 0.16.53

• Browser:
  all

• Language:
  TypeScript

Current behavior:
When following the given readme for skeleton-typescript after trying to execute the test-skeleton. (installing etc works). The following errors (in part) occur:

X:/node_modules/typescript/lib/lib.dom.d.ts(3913,11): error TS2300: Duplicate identifier 'Headers'.
[03:05:04] gulp-notify: [Error running Gulp] Error: X:/node_modules/typescript/lib/lib.dom.d.ts(3913,11): error TS2300: Duplicate identifier 'Headers'.

[03:16:56] gulp-notify: [Error running Gulp] Error: typings\globals\whatwg-fetch\index.d.ts(41,15): error TS2300: Duplicate identifier 'Headers'.

I've truncated a lot of similar errors ("duplicate identifier"), the X:/ is the location where I've created the project with the skeletal build.

I've tried following the solutions given #775 But those don't seem to solve the problem (npm uninstall @types\whatwg-fetch) - I presume this is due to the skeletal builds not using @types declaration but rather the deprecated typings module?

Expected/desired behavior:

I expect the skeletal builds to fully work with the newest libraries of aurelia/typescript - since they're created for those?

Seeing the same issue. Any updates on this? (Or anything I can do to help?)

[joelowrance]

Based on a similar issue found here https://github.com/DefinitelyTyped/DefinitelyTyped/issues/16509, adding "skipLibCheck": true to the tsconfig,json file at least works around this.

Cloned repo.
Changed directory to skeleton-typescript
executed yarn
executed yarn jspm install
executed yarn gulp watch

no problems found.

git clean -d -x -f

npm install
.\node_modules.bin\jspm install
.\node_modules.bin\gulp watch

no problems found

node -v
v8.9.4

npm --version
5.6.0

Can you retry?
Oh.. I did it with master.. will have to retry with latest release

[joelowrance]

@Alexander-Taran I have retried against master and everything is fine. Seems to be an issue only with the released version (which is the recommended download in the docs).

[Alexander-Taran]

Now this transforms into a huge task (-:
Check all other skeletons on master.
Update to webpack 4
Check and update all documentation referencing skeletons
and release

help_needed

[paul23-git]

This problem is indeed with the "archive download" from the documentation. ("start here").

[Alexander-Taran]

@pulli23 what documentation is that?
could not find it

[plwalters]

The TypeScript skeleton has another issue it seems -

// Error: (SystemJS) Cannot read property 'base64encode' of undefined

When cloning a clean skeleton and installing fresh deps from npm and jspm this error is thrown. Trying to figure out the cause now but I think the tests are broken on latest release.

[plwalters]

Disregard looks like it is a known TS issue - microsoft/TypeScript#24638 - that has a fix about to release.

[Alexander-Taran]

@3cp I think we can close this..
