Ts-node: E2E typescript tests are not being transpiled after Angular upgrade Ask

[akisiel1]

Hi!

I have a problem with e2e tests after the upgrade to the Angular 6. Problem is described in more details on StackOverflow:
https://stackoverflow.com/questions/52420169/e2e-typescript-tests-are-not-being-transpiled-after-angular-upgrade

I think it might be problem on angular-cli or ts-node side.

I use "ts-node": "7.0.1" and "typescript": "2.9.2"

Can anyone look at it?

When reporting an issue, please try to narrow down the cause or have something reproducible, especially if you believe it's a bug in ts-node. Based on your StackOverflow post, it's an issue with your types:

e2e/....e2e-spec.ts(27,111): error TS2322: Type '0' is not assignable to type '{ label: number; sent: () => any; trys: any[]; ops: any[]; }'.

Hi @blakeembrey !

Sorry if the task's description is too wide, but the problem is pretty complex. If you might see on the bottom, there is a note that proves that it is not a problem of my types, but of not transpiled files.

Your problem is your module output in your configuration then. Node.js can’t execute ES2015 modules, you need the module to output CommonJS.

Hi!

I tried with both, nothing worked :/

But one of my team mates have finally found that the problem was in one of the npm packages. We were needed to downgrade:

"tsconfig-paths": "3.6.0",
"ts-node": "~5.0.1",
"tsickle": ">=0.25.5",
"tslib": "^1.7.1",
"tslint": "~5.9.1",

and upgrade:

"protractor-image-comparison": "^2.0.0",

I don't know which package caused that issue with newest Angular, unfortunately I didn't have more time to investigate that.
