How did you run the script?

[alialpha123]

ruby stackskills_dl.rb -c courselink

[yoonwaiyan]

What's the output in your terminal for $ ruby ? Seems like a problem with your Ruby executable.

[alialpha123]

after writing ruby in terminal nothing comes

[yoonwaiyan]

I've updated the source to force use Ruby in the script, can you update the code and try again?

[alialpha123]

this is coming now

Ok, please run bundle install to install the dependencies before running the script. If there's a problem about bundler not installed, please run gem install bundler, and then run bundle install then run the script again.

[alialpha123]

after using gem install bundler and then bundle install this is coming

An error occurred while installing nokogiri (1.6.7.2), and Bundler
cannot continue.
Make sure that `gem install nokogiri -v '1.6.7.2'` succeeds before bundling.

[yoonwaiyan]

seems like you have missing zlib library which is required for Nokogiri. Please install zlib1g-dev (in Ubuntu it's sudo apt-get install zlib1g-dev) and run bundle install again.

[alialpha123]

thanks it worked

[yoonwaiyan]

Ok, closing this issue.
