【问题描述】：
当我尝试通过 heroku run rake 迁移到 heroku 我收到以下错误：
Running rake on ⬢ friends-clique... up, run.8185

DEPRECATION WARNING: The configuration option `config.serve_static_assets` has been renamed to `config.serve_static_files` to clarify its role (it merely enables serving everything in the `public` folder and is unrelated to the asset pipeline). The `serve_static_assets` alias will be removed in Rails 5.0. Please migrate your configuration files accordingly. (called from block in <top (required)> at /app/config/environments/production.rb:82)
Abort testing: Your Rails environment is running in production mode!
我以为 heroku 是在生产模式下运行的，刚刚发生了什么？
【问题讨论】：
-
您是否在本地以生产模式运行项目？
-
你和 Bootstrap 有 gem 冲突，检查你的 gemfile，也试试
heroku run bundle install -
您正在运行的确切命令是什么？
-
你的 Heroku 日志是怎么说的？
-
你在 heroku 上的
RACK_ENV和RAILS_ENV是什么？您可以通过运行heroku config来获取此信息。
