我已经检查过每一篇关于此的帖子，但它似乎没有解决我的问题.. 这就是我试过的
在config.assets.compile = false中将true更改为environment/production因为它可能是编译中的问题（参考此Heroku — "We're sorry, but something went wrong"）
heroku run rake db:migrate ..在大多数情况下似乎是解决方案，但问题是我没有数据库..它显示了这个结果
Running `rake db:migrate` attached to terminal... up, run.3272

我认为我的Gemfile在这里可以：
source 'https://rubygems.org'
ruby '1.9.3'
gem 'rails', '3.2.13'
group :development do
gem 'sqlite3'
end
group :production do
gem 'thin'
gem 'pg'
end
还有这个
-----> WARNINGS:
Removing `Gemfile.lock` because it was generated on Windows.
Bundler will do a full resolve so native gems are handled properly.
This may result in unexpected gem versions being used in your app.
每当我部署我的应用程序时，这个东西就出现了。我在重写Gemfile之前删除了这个文件，但是当我在应用程序中部署它时它就生成了。
可能导致什么原因？
答案 0 :(得分：1)
你的heroku错误是
ActionView::Template::Error (cannot load such file -- uglifier
请添加宝石
gem 'uglifier'
在Gemfile中
2）然后在本地
中运行bundle install3）然后git add，git commit，git push heroku
答案 1 :(得分：1)
你缺少uglifier gem。你需要添加它并推送到heroku
group :assets do
gem 'uglifier'
end
