how do i include flex-layout

问题

I'm trying to add flex-layout to an angular app, but when I do and try to use it the app breaks. I've installed

npm i @angular/flex-layout @angular/cdk

then imported in app.module.ts

import { FlexLayoutModule } from '@angular/flex-layout';

import [ FlexLayoutModule ]

I've also upgraded typescript to the latest

npm i typescript@latest

But when the app tries to compile, I get all kinds of errors:

ERROR in node_modules/@angular/flex-layout/core/typings/base/base2.d.ts:24:19 - error TS1086: An accessor cannot be declared in an ambient context.

24     protected get parentElement(): HTMLElement | null;

       ~~~~~~~~~~~~
node_modules/@angular/flex-layout/core/typings/breakpoints/break-point-registry.d.ts:24:9 - error TS1086: An accessor cannot be declared in an ambient context.

and the list goes on. Do I have a version mismatch of something?

Thanks.....

回答1:

Try to add tslib in dependencies

npm install --save tslib

Edit

If you are using Angular v8 then use v8 for flex-layout cause v9 need Angular v9.

回答2:

It's because you are on Angular 8 but the library required Angular 9. In your package.json use this version : "@angular/flex-layout": "^8.0.0-beta.27"
