Sometimes when you install angular with yeoman you get some issues. Here are a few solutions. From https://github.com/gruntjs/grunt-contrib-imagemin/issues/109

angular-yeoman

You don't have to add "jpegtran-bin": "0.2.0" to package.json
Remove node_modules folder if necessary
Do npm install [email protected]
Do npm install
It worked for me.

karma

If the console runs this error:

Running "karma:unit" <karma> task
Warning: No provider for "framework:jasmine"! <Resolving: framework:jasmine> Use --force to continue.

Aborted due to warnings.

then try to install:

npm install karma-jasmine --save-dev
npm install karma-chrome-launcher --save-dev
(or for more launchers)
npm install --save-dev karma-chrome-launcher karma-firefox-launcher karma-safari-launcher karma-opera-launcher karma-ie-launcher karma-jasmine

yeoman angular issus

If you have some errors try:
Delete the folder node_modules
npm cache clear
npm install
