"bundler:command not found:thin"heroku部署rails

Question

所以我的应用程序在我的本地机器上运行完美,我成功地将它推送到github和heroku但是当我尝试在浏览器中打开应用程序时,我收到以下错误:

Application Error
An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

然后我尝试跑步

$ heroku logs

我在控制台中获得以下输出:

我无法想象如何制作这个,因为这是我第一次部署到heroku而我对网络部署一无所知.任何帮助将不胜感激!

Answer 1

对我来说问题是我在开发部分为我的Gemfile添加了瘦,但是一旦我这样做,heroku就想用它进行生产,但是没有在开发部分安装gem.通过将精灵宝石移出开发部分以供所有环境使用,我能够克服此错误.

对于Rails应用程序,您的Gemfile可能看起来像这样:

source 'https://rubygems.org'

gem 'rails'
gem 'heroku'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'pg'
gem 'thin'

# more gems

无论如何,Heroku 建议使用瘦身作为生产网络服务器.

更新(2012-05-16):在Heroku上面的Rails 3网络服务器链接现在推荐了独角兽.瘦还可以,但你可能想考虑切换到独角兽.

您的 Gemfile 中可能缺少一个 gem。确保您的应用程序需要的所有内容都在 Gemfile 中指定，而不是在本地执行“gem install”。要进行验证，您可以安装RVM，专门为您的应用程序创建一个 gemset，在您的应用程序目录中运行“bundle install”，然后查看您的应用程序是否在本地运行。如果它不运行，则肯定缺少宝石。
