Platform: TypeScript errors during build process...

[tracker1]

I'm submitting a...

[ ] Regression (a behavior that used to work and stopped working in a new release)
[ X] Bug report  
[ ] Feature request
[ ] Documentation issue or request

What is the current behavior?

About every other build, I seem to be seeing a lot of TS1005 and TS2314 errors all related to .d.ts files in the @ngrx/* in the node_modules directory

Expected behavior:

build without errors

Minimal reproduction of the problem with instructions:

frankly not sure why this is happening, I'm a relative novice with angular and typescript to begin with, but not seeing these from other packages.

Version of affected browser(s),operating system(s), npm, node and ngrx:

happening in both windows and osx, node v8.6.0, ngrx see below.

The ones that are in my own code, are somewhat weird, for example my use of the @ngrx/router-store is pretty much a mirror of the docs/router-store/api.md

It says there are two type argument parameters required.

[brandonroberts]

Most likely your version of TypeScript is incorrect. Can you provide more details about your environment?

I'm seeing similar behavior in an Angular4 project (quite clean, boilerplate) where I'm trying to get @ngrx/store to work. I've just been following the examples as described on the website, but I also keep running into errors like these:

I'm running TypeScript 2.5.3, in combination with ng-cli 1.4.5 which both seem quite up to date.
I've checked if there weren't any weird settings in my tsconfig.json but I couldn't detect any with my current knowledge.

In the package.json there's a lot, but most important for this issue are:
'@angular/<xxx>': '^4.0.0'
"@ngrx/store": "^4.0.3"

These seem to match quite actual versions I'd say?

Any idea on what's going on?

ninja edit: Noticed this issue is in @ngrx/platform, it could be specific to @ngrx/store but I haven't tested that yet.

[brandonroberts]

This seems like a local issue. Provide a reproduction of the issue. For further support, please use the support channel https://gitter.im/ngrx/platform

[aliszafar1]

+1

[brandonroberts]

The current officially supported version of TypeScript for Angular apps is 2.4.2. if you are using that version and still having issues, provide a reproduction.

[aliszafar1]

typescript 2.4.2
angular cli 1.5.4
@angular 5
@ngrx/core 1.2.0

[brandonroberts]

@aliszafar1 you need to remove @ngrx/core from your project if you are migrating to V4

[aliszafar1]

I have created project on angular 5, not migrating

[aliszafar1]

@brandonroberts issue resolved, thanks for your cooperation :)

[Isterius]

@aliszafar1 maybe some informations about HOW this was resolved ?
