How to resolve “You need to have Ruby and Sass installed and in your PATH for this task to work” Warning?

Question or issue on macOS:

I am in the process of setting up a new Mac for work. I have installed Grunt & Grunt CLI globally. Then I did a npm install inside a project folder to install all dependencies.

No problems so far, but as soon as I try to run the sass:dist task, I get this warning:

Warning: You need to have Ruby and Sass installed and in your PATH for
this task to work. More info:
https://github.com/gruntjs/grunt-contrib-sass Use --force 
to continue.

What I understand is that I need to have Ruby and Sass installed on a more global level for this task to run. As I am still pretty new to working with the terminal, I did a quick search to find out what PATH is – seems like its some system path (that can be changed) where important data is stored.

Does this mean I can simply do a sudo grunt install contrib-sass -g to resolve the issue? And what about Ruby – I always thought its already installed on OS X?

How to solve this problem?

Solution no. 1:

Ok I got it. I just had to install Sass using gem install sass and now everything is fine…couldn’t be easier.

Solution no. 2:

If you’re on OSX El Capitan or Yosemite on Mac there seem to be an issue installing the gem.

Try

sudo gem install -n /usr/local/bin sass

Solution was from github.

Solution no. 3:

You need to install Ruby and Sass as:

For Ruby use command

sudo apt-get install ruby-full

And for Sass use command

sudo gem install sass

Solution no. 4:

grunt-sass documentation is not very clear. To avoid the need of Ruby, you can try this:

npm uninstall –save grunt-contrib-sass

npm install –save node-sass grunt-sass

Try this, It’s work for me.

sudo gem install sass

Solution no. 6:

Use grunt –force if you are using grunt.
If you want to run an application using grunt and a warning is occur like this. For ignoring this warning you can use –force.

Solution no. 7:

Also simply brew install saas/sass/sass on Mac High Sierra (10.13.x)

Solution no. 8:

I used Homebrew to install Ruby and then Ruby to install SASS. Probably only the best way to do it if you already use Homebrew, or want to start using it regularly…

brew install ruby
gem install sass

Hope this helps!
