【问题描述】：
我已经检查了所有关于此的帖子，但它似乎并没有解决我的问题.. 这是我尝试过的
将environment/production 中的config.assets.compile = false 更改为true，因为这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 在这里还可以：
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，这个东西就会出现。我在重写 Gemfile 之前删除了这个文件，但我猜它是在我将它部署到应用程序时生成的..
可能是什么原因造成的？
【问题讨论】：
-
您的日志显示它没有找到 uglifier gem。你在 GemFile 中添加了这个吗？如果没有，则添加 group :assets do gem 'uglifier' end ，然后推送到 heroku。
-
就是这样，非常感谢！因此，如果缺少 gem，我只需将其添加到 Gemfile 中？
-
是的。没关系。请参阅下面的答案。
