Above command actually goes to jQuery site to download dependency files. It might be the case that you don’t have Internet connection or slow connection problems.
If problem persists try to manually copy required files.
Thanks for the quick reply Sandip!
I think that this is maybe something else, even though it is in the timeout method. Note the error message:
certificate verify failed (OpenSSL::SSL::SSLError)
Also, my internet connection is great. Also, I could download the files – which ones? Where do I find them, and do they all go into public/javascripts?
