Answer 1

You are using the following semver in your package.json for the @types/jasmine package:

"@types/jasmine": "^2.8.3"

The ^ implies that your package installer will download the latest minor version that's out there available for the said package, which in this case is 2.8.11. (If you visit https://www.npmjs.com/package/@types/jasmine you will notice that they released their latest version 2.8.11 20 hours ago.)

There are two ways to go about solving your problem: 1) Make sure your Typescript version is compatible with the @types/jasmine package 2) Lock down your version to a specific one (2.8.8 is fairly stable). Hope this helps!

Answer 2

Try changing the @types/jasmine version to "@types/jasmine": "2.5.38" and reinstall.

Here you can find a long discussion about it.

Answer 3

I got a similar error and locked the jasmine version to the latest working version, which for me was

"@types/jasmine": "2.8.9"

However, i ran into another issue because I am using karma-jasmine-html-reporter

https://www.npmjs.com/package/karma-jasmine-html-reporter

So I locked the version for this package as well to the latest working version, which for me was

"karma-jasmine-html-reporter": "1.3.1"

After these two changes the build was working again for me.

Be sure to remove the locks once another working version of jasmine and karma-jasmine-html-reporter comes out.
