grunt-contrib-htmlmin | - Minify HTML

I've tested your package.json on npm 3.5.2, node v8.2.1 and Linux Ubuntu 17.10. It hang on at the same point:

i found a solution for my problem to open automatically the browser i added the parameter livereload to connect object in my Gruntfile configuration

try

After a lot of keyboard facerolling, I've come to this solution:

• remove that directive/**/*.html from karma.options.files task configuration, since a) it's not enforcing project "folders-by-feature" structure and b) instead getting the templates from '<%= ngtemplates.main.dest %>' it's solid enough, you just need to change the grunt test task into grunt.registerTask('test',['dom_munger:read','ngtemplates','karma:all_tests']);

• remove beforeEach(module('directive/test-directive/test-directive.html')); from test-directive-spec.js, since it looks like it clashes with the previously described ngtemplates mechanism, making the template unavaiable;

This error clearly states that angular2-in-memory-web-api@0.0.21 requires older version of rxjs. Try to update angular2-in-memory-web-api to the latest version which is actually shipped under new name angular-in-memory-web-api.

Well, the GruntJS FAQ says that,

You probably created an alias task with the same name as one of your regular tasks

Example: grunt.registerTask('uglify', ['uglify:my_target']); should be grunt.registerTask('myUglify', ['uglify:my_target']);.

Please check if you have made any mistakes as such.

Hope this helps!
