ERROR in [at-loader] node_modules\@types\jasmine

Question

My webpack build started failing out of nowhere with no packages being updated. I assume some minor version update caused this, but can\'t figure out how to get around it. D

Answer 1

Looks like your @types/jasmine library was upgraded to the latest version since you have the caret symbol:

"@types/jasmine": "^2.2.34",

The latest version is having issues as this bug suggests. So try for now by setting the version to 2.5.41 in your package.json :

"devDependencies": {
  "@types/jasmine": "2.5.41"
}

Maybe you have to delete your node-modules folder and run npm install for a clean installation.
