Angular 9: Compile error

[nlitterat]

I found a solution at least for my case
I added

{
  "scripts": {
    "postinstall": "ngcc"
  }
}

and the problem was gone
This is needed when you are using the new Ivy compiler
I hope this will help

[fahadjabbar8]

Any update on this i am getting this error for ngcc ?

[jonnyrocks]

A workaround is to disable Ivy compiler in Angular 9.
put below in tsconfig.json

  "angularCompilerOptions": {
    "enableIvy": false,
  }

Yeah, that works but the main reason to upgrade to Angular 9 would be to use Ivy compiler. So disabling it just for this component isn't a good idea. I have used ngx-highlightjs instead. It is not as cool as ngx-prism but does the job.

Same issue here, looks like lib is dead

[joshijimit]

Hi Hau,

I am also facing same issue. Looks like this package is no longer maintained by the authors. So either we need to find the alternate or try to upgrade it to support Angular 9 ourselves.

Will let you know if I find any luck. Please update me if you get around it too.

Thanks.

having same problem. I think its angular problem(ivy)

[nas90]

I'm also having the same issue, running on Angular 9 with Ivy enabled

[nlitterat]

Same here

[ndesimone]

{
  "scripts": {
    "postinstall": "ngcc"
  }
}

The internet wins. Thank you @nlitterat, this worked perfectly for me.

Not sure why but I get the following error while running ngcc:

Warning: Invalid constructor parameter decorator in G:/APPS/avalon/ama-code-editor-frontend/node_modules/@ngx-prism/core/dist/prism.service.js:
 () => [
    { type: DomSanitizer, },
]
Error: Error on worker #2: Error: getInternalNameOfClass() called on a non-ES5 class: expected PrismService to have an inner class declaration

🤷 Tried removing node_modules and doing a clean install but still, once ngcc runs that error comes up.

Erro será resolvido consultando o seguinte link conforme a versão do Angular: https://github.com/ngx-translate/core

"postinstall": "ngcc" fix problem but not work in IE: Invalid character in function getColors.
Any ideas?

[elmota]

"postinstall": "ngcc"

"postinstall": "ngcc"

where do you type that?

Package.json -> scripts
