grunt-karma ^2.0.0 installs karma@1.0.0 and tests don't work

[gugol2]

When installing grunt-karma npm install grunt-karma --save-dev it install karma^1.0.0 with it. And that breaks the tests:

Warning: .then() only accepts functions but was passed: [object Undefined], [object Undefined]...

More info here.

Can you provide a repro project? My tests run fine with karma@1.0

[gugol2]

Create an angular project with yeoman (using grunt, not gulp) and try running the tests.

Does not reproduce it for me: This project works fine for me: https://github.com/dignifiedquire/grunt-karma-192

Sorry for my delay.

It's quite strange, I get it when running grunt on windows but not in linux.
I tested your repo in W7 and Ubuntu14.04 and it only fails in W7.

It also happens just the same with my repo.

So in W7 I sorted out by installing the the version that grunt-karma needs according to the docs:

This current version uses karma`@0.13.x ...

npm install karma@0.13.22 --save-dev

Although it the tables it seems to depend of different versions of karma for devDependencies(1.x || ^0.13.0) and peerDependencies(^0.13.0 || >= 0.14.0-rc.0)

With currently supported versions of Node.js and npm (Node 6+, npm 3+) peerDependencie are not automatically downloaded (unlike regular dependencies). Instead, it is up to the project to decide what and which version to install.

As such, any version of karma and any version of grunt-karma can be used together. The peerDependencies only prints a soft warning if they don't match what we recommend and support.

The karma 1.x support has been been added and released, so closing this report. See #267 for a similar issue with karma 3.x, which we're fixing next.

Thanks!
