当我输入heroku open时，它会显示“我们很抱歉，但出了点问题。”有谁知道为什么会这样？
答案 0 :(得分：2)
资产应该预先编译 添加到您的config / application.rb
config.assets.initialize_on_precompile = false
更多信息： https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar/
答案 1 :(得分：1)
您需要先在本地编译资产。
看看这里：https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar
在推送到Heroku之前尝试以下内容。
RAILS_ENV=production bundle exec rake assets:precompile
答案 2 :(得分：0)
在服务器上迁移数据库。
尝试预编译资产管道
答案 3 :(得分：0)
当您创建heroku堆栈时，请执行此操作，而不仅仅是heroku create：
heroku create --stack cedar
并确保在推送到heroku之前执行此操作：
heroku run rake db:migrate
