答案 0 :(得分：2)
你正试图在Heroku上启动rails/server并且你没有在Heroku上安装spring（这很好，你在Heroku上不需要它），这是一个错误。
您似乎没有设置Procfile，或者如果您设置了rails/server，而不是生产网络服务器。 Heroku recommends Puma as the webserver你也可以使用Unicorn。
按照上面链接中的说明为heroku设置Puma。基本设置是创建Procfile和config/puma.rb文件。
如果您使用的是Puma或Unicorn，则不会使用rails/server，因此不会尝试加载弹簧。

1.替换
gem 'spring', group: :development
通过
gem 'spring'
。 然后运行
bundle install
更新Gemfile.lock并提交更改并将代码推送到heroku。
它应该工作。
因为弹簧在开发中被分组所以找不到这个宝石但是当你移除这个组时它将在生产模式中找到
