Modernizr 2 很容易从 rails-assets 安装.
# Gemfile
gem 'rails-assets-modernizr'
# application.js
//= require modernizr
但是，modernizr 3 文档说:
A lot has changed since the last version of Modernizr. There no longer is a single, base modernizr.js file. Instead, just head over to the Download page as you could have previously, and select the features you want to use in your project. https://modernizr.com/docs/
这听起来好像我再也无法从 rails-assets 中获得 Modernizr 3 了。这是真的？
正如预期的那样，如果我尝试从 rails-assets 安装 Modernizr 3，我会得到:
An ActionView::Template::Error occurred ...
couldn't find file 'modernizr' ...
app/assets/javascripts/application.js:20
最佳答案
我没有让 v3 工作。我通过像这样更改我的 gemfile 将版本降低到 2.8.3:
source 'https://rails-assets.org' do
gem 'rails-assets-respond'
gem 'rails-assets-modernizr', '2.8.3'
end
