Google-Maps-For-Rails not showing map in Rails 3.1

I am trying to use the gem 'gmaps4rails'开发者_运维百科. I inserted all of the necessary code into my model and view, and I know that the geocoding is working. However, when I insert the code <%= gmaps4rails(@json) %> into my index.html.erb file, the map does not appear.

EDIT: I downgraded the version to 0.8.8, and I was able to run rails g gmaps4rails:install to get the layouts. Does version 0.9.1 have a different command for installing the layouts?

I was having the same problem (couldn't get the generator installing) and getting the 404 for gmaps4rails.js.

The following steps worked (you had most of it).

• I downgraded to 0.8.8;
• ran the generator;
• then copied the generated files from public/ to assets/;
• changed back to version 0.9.1.

and it worked fine after that (i.e. map showing).
