Test Error with Angular Web Stagehand Template

[tsteward]

I create the default web-angular using Stagehand.

I run this command to run tests as described in documentation:

pub run build_runner test --fail-on-severe -- -p chrome

I get the following error:

PS D:\Users\tstew\playground\angular_test> pub run build_runner test --fail-on-severe -- -p chrome

@tsteward can you try running in a console with admin privileges? I think this might be due to a recent change in the sdk, see dart-lang/sdk#33966 for context.

[jakemac53]

If that does in fact repro the issue we can add a try/catch here https://github.com/dart-lang/build/blob/master/build_runner_core/lib/src/environment/create_merged_dir.dart#L97 and try to handle it more gracefully.

[tsteward]

When I run in an admin console I don't get the error.

[jakemac53]

Ok, thanks. It looks like we get a pretty specific error code 1314 that we can check for at least.

I am not sure what the proper behavior should be for us - unfortunately it doesn't look like we can fall back on junctions but copying the entire contents of the packages dir isn't really an option either.

@jakemac53 I'm also hitting this issue when using firebase functions interop in dart...noticed this has been open for a while.

[jakemac53]

Oh, this issue should actually be closed. We have implemented the explicit check for this exception and will point users at the docs for how to enable developer mode in Windows which resolves the problem without needing an elevated console.
