Warning triggered Grunt cancellation

I've successfully installed "npm" on my local machine. When it comes to installing grunt in my Gruntfile.js directory, I follow these steps:

  1. npm install grunt
  2. npm install -g grunt-cli
  3. grunt watch

Although the tasker is up and running, I encountered some warnings: https://i.sstatic.net/Y0FVK.jpg

Check out my gruntfile.js file below:

Answer №1

To resolve the issue, it is essential to ensure that all missing grunt tasks are installed. If you have a package.json file containing the required dependencies, executing npm install in the same directory will suffice.

If there is no package.json file available, each task can be manually installed using the following commands in the command line:

    npm install grunt-sass
    npm install grunt-contrib-watch
    npm install grunt-contrib-jshint
    npm install grunt-contrib-cssmin
    npm install grunt-autoprefixer
    npm install grunt-contrib-uglify
