Error from running rails g polymer:install #88

Open dshukertjr opened 7 years ago

dshukertjr commented 7 years ago

I'm new to using rails and polymer, and I followed the instruction in the README.md, but $rails g polymer:install command did not work.

Here is the output from running $rails g polymer:install

Now, after getting this, I googled for some clue, and found out that using sprocket version 3 or higher would result in an error like this. So I inserted the following into my gem file

gem 'sprockets', "< 3.0.0"

which resulted in this error message when I run $ bundle update sprockets

`Bundler could not find compatible versions for gem "sprockets": In Gemfile: sprockets (< 3.0.0)

rails (~> 5.0.1) was resolved to 5.0.2, which depends on
  sprockets-rails (>= 2.0.0) was resolved to 3.2.0, which depends on
    sprockets (>= 3.0.0)

`

At this point, I am kind of stuck. Does this mean polymer does not work on rails 5.0.1? Do I have to use rails version 4?
