angular 8 flex-layout 8 error : has no exported member ɵNgClassImpl error

Question

I Have angular 8 project and tried to install flex-layout 8.0.0-beta.26. I get this error on build.

ERROR in node_modules/@angular/flex-layout/extended/typings/class/class.d.ts(9,19): error TS2305: Module '"C:/Users/user/Desktop/Project/node_modules/@angular/common/common"' has no exported member 'ɵNgClassImpl'.

    "rxjs": "~6.3.3",
    "tslib": "^1.9.0",
