I'm experiencing an issue where I have Node.js v0.12.0 installed with Karma on my OS X Yosemite, but when I try to run my test task using Gulp, it just hangs as shown in the picture. It seems like PhantomJS is not starting. Interestingly, the same code works fine with Node.js version v0.10.32, but not with v0.12.0. Can anyone provide guidance on how to get Karma running smoothly with Node.js v0.12.0?
Thanks
Regrettably, Karma v0.12.31 is not compatible with the most recent stable version of Nodejs (v0.12.0). The Karma website states in the Installation > Installing Node.js section:
Note: Karma only functions on the two latest stable versions, which are currently 0.8.x and 0.10.x.
Despite Nodejs being at version v0.12, the Karma team has yet to update the project for compatibility. There is an unresolved issue on Github related to this problem:

To work around this, you can use node version manager (nvm) to install an earlier release such as 0.10.x of Nodejs. This will allow you to use the current version of Karma by having multiple Nodejs versions installed using nvm.
