Class constructor TranslateCompiler cannot be invoked without 'new'

Hi from Brazil!

I'm trying to use TranslateMessageFormatCompiler in an Angular 7.1 project, however, my application doesn't work, as the following error is thrown:

Angular CLI: 7.3.10 Node: 13.12.0 OS: win32 x64 Angular: 7.1.4 @ngx-translate/core: 13.0.0 ngx-translate-messageformat-compiler: 4.7.0 messageformat: 2.0.5

In my app.module imports:

And providers:

I appreciate if you can help me.

Is there anything we should provide to narrow this down?

@lucasskluser Did you find a solution?

A quick internet search tells me that this probably has to do with module formats and/or what language level is targeted by the library and/or the app including it. I know that's vague, but the thing is: this library provides all kinds of builds (using the standard Angular CLI setup for libraries) and this error does not occur with a default Angular CLI setup for the app using it.

I suggest you try to find the difference between your app setup and the sample projects or the StackBlitz app. Check tsconfig.js (there's usually more than one), angular.json and package.json especially.

@jessorlisa / @lucasskluser Do you have a specific webpack config? The default one from angular should just work fine. I had the same issue using this module in Storybook. I found a way to fix this, thanks to this issue: https://github.com/storybookjs/storybook/issues/11379#issuecomment-662953505

This configuration is done by angular-cli in the hidden webpack config.
