No exported member 'ErroredTrait'.

[George B]

node_modules/ngast/lib/ngtsc/symbol.d.ts:26:306 - error TS2694: Namespace '"@angular/compiler-cli/src/ngtsc/transform"' has no exported member 'ErroredTrait'.

26 export declare const isAnalysed: <A, B, C>(trait?: import("@angular/compiler-cli/src/ngtsc/transform").PendingTrait<A, B, C> | import("@angular/compiler-cli/src/ngtsc/transform").SkippedTrait<A, B, C> | AnalyzedTrait<A, B, C> | ResolvedTrait<A, B, C> | import("@angular/compiler-cli/src/ngtsc/transform").ErroredTrait<A, B, C> | undefined) => trait is AnalyzedTrait<A, B, C> | ResolvedTrait<A, B, C>;

I noticed that remove the concept of an errored trait was undertaken here
angular/angular#39923

ErroredTrait is no longer in the code
https://github.com/ng-ast/ngast/blob/master/lib/ngtsc/symbol.ts

but it seems that the npm package still has the outdated code
"ngast@0.6.1"

Would this be the case?

Yes, just fixed this yesterday. Feel free to update to 0.6.2.
