'"@angular/core"' has no exported member named 'input'.

[compact plume]

Good evening, Do you know why I cannot use "input"? How can I fix this?
Angular CLI: 17.3.4

[cyan fiber]

Uppercase I in Input

Looks like you already have it imprted. Just delete the lower case i input import.

[compact plume]

no I need with lower case. I am following a tutorial for Using Signal inputs

https://angular.io/api/core/input like here

[tepid mango]

Version of the CLI doesn't really matter. What is the version of @angular/corethat you have installed?

[compact plume]

"@angular/core": "^17.0.1",

[tepid mango]

Hm. Should work. Hard to say without further input. Might even just be an IDE glitch.

[compact plume]

how can I fix this if it is an IDE glitch?

[tepid mango]

Does ng serve or ng build work?

[compact plume]

before yes, after using "input" not more, because I have now couple of errors

it works but I recieve an error

[tepid mango]

Is the input the same, that it cannot import it? Or other?

What do you mean by that exactly?

the error the same* is what I meant, sorry.

[compact plume]

so it works, but I have errors here

[tepid mango]

The errors are in your IDE. So this definitely looks like an IDE problem.

Make sure VSCode and Extensions are up to date. (I don't use VSCode, I don't know how Angular support works there)

[compact plume]

which one do you use?

[tepid mango]

I use WebStorm

But it's not free 😄

[compact plume]

okeee, thank you

[runic bronze]

What's the error text when you hover it?

[compact plume]

Property 'ɵINPUT_SIGNAL_BRAND_WRITE_TYPE' does not exist on type 'typeof import("c:/Users/sanzha64/udemyAngular/angular-course/node_modules/@angular/core/index")'.ngtsc(2339)
app.component.ts(14, 70): Error occurs in the template of component AppComponent.
(property) UserComponent.avatar: any

[runic bronze]

Weird indeed

[compact plume]

but now it doesnt work, I didnt change anything ...hhm

[tepid mango]

Are you on Windows? Try importing only input, not Input and input.

[compact plume]

yes windows, no changes

[tepid mango]

Sorry, I misread the error message. Are you using NPM?

[compact plume]

yes

[tepid mango]

Can you please run npm ls @angular/core and show the output?

[tepid mango]

This is very strange. All I can think of is delete node_modules and reinstall 😂

[compact plume]

ok thanks, I will try

[analog inlet]

ng version will tell you what you exactly have

[analog inlet]

So yeah 17.0.1.

Can you give use the package.json ?

[compact plume]

[analog inlet]

quickest way, delete the node modules and the lock file

[compact plume]

lock file? package.json?

[analog inlet]

package-lock.json or yarn.lock

[compact plume]

after delete and npm install I receive this error

[analog inlet]

restore your package.json

you need to keep it

[compact plume]

restored and reinstalled npm, I receive the same error when I do ng serve

[runic bronze]

inputhas been introduced in 17.1, you need to update your angular dependencies.
That's a good opportunity to update to 18 directly with: ng update @angular/core@18 @angular/cli@18

[runic bronze]

Morel likely due to a corporate firewall?

[compact plume]

it works (I mean "input") in other projects, so only in angular-course not

[runic bronze]

what's the angular version in package.json of these projects?

[compact plume]

in other projects 17.3.4, in this 17.0.0

[runic bronze]

Like i told you => introduced in 17.1

[compact plume]

I have now 18.1.4. I deinstalled it an reinstalled. But I have the same problem..

[runic bronze]

plese show your updated package.json file

[runic bronze]

@compact plume as explained at the start of the discussion, the global Angular CLI does not matter, what's matter is the version INSIDE your project.

The global one is useful to create projects. By using ng new you'll get a new one with 18.1 for example but it won't afffect existing ones.

[compact plume]

Can I deinstall angular und delete the text inside package.json and install @angular/core@18 @angular/cli@18

[runic bronze]

with the ng update command i shared you earlier it should work. But you are more likely under a corporate firewall (besides being weird installing angular-cli globally works). I'd get it fixed by asking internally.
