Typescript: "i ｢wdm｣: Failed to compile."

Question

My Typescript build is failing but I don't know why. "i ｢wdm｣: Failed to compile." is the error message. It's cryptic with funny characters. How do I get the build error to show properly?

I'm using IIS Express, ASP.NET Core and Angular in this project.

Here's a more detailed log

Answer 1

I had the same error. For a more verbose error message:

• Open a command line
• Go to your app directory (e.g. ClientApp)
• Build the Angular app: ng build
