Can't resolve web-animations-js in ASP.NET Boilerplate template

I created a new project from the ASP.NET Boilerplate 3.0.0 template today (10 Oct 2017) and I ran yarn install in the \angular folder.

I then ran npm start and I get the error message:

ERROR in ./src/polyfills.ts
Module not found: Error: Can't resolve 'web-animations-js' in 'C:\Source\asipsa\angular\src'
resolve 'web-animations-js' in 'C:\Source\asipsa\angular\src'
  Parsed request is a module
  using description file: C:\Source\asipsa\angular\package.json (relative path: ./src)
    Field 'browser' doesn't contain a valid alias configuration
  after using description file: C:\Source\asipsa\angular\package.json (relative path: ./src)
Solution

  • I figured out the problem. The startup template is missing a dependency for web-animations-js.

    To fix run yarn add web-animations-js and then you can run npm start and it will run correctly.
