Question

过去，我已经部署到Heroku，但问题很少。今天我创建了一个非常基本的应用程序（字面上只是默认的＆＃39; new＆＃39;带有更新的gemfile）并将其推送到Heroku。

然而，Heroku并没有认识到这个春天＆＃39;宝石，即使它在Gemfile中列出。它导致我的应用程序崩溃。在它被问到之前，是的，我在更新Gemfile后运行了bundle install和bundle update。

Gemfile（从RoR教程中直接复制粘贴）：

source 'https://rubygems.org'

gem 'rails',        '4.2.2'
gem 'sass-rails',   '5.0.2'
gem 'uglifier',     '2.5.3'
gem 'coffee-rails', '4.1.0'
gem 'jquery-rails', '4.0.3'
gem 'turbolinks',   '2.3.0'
gem 'jbuilder',     '2.2.3'
gem 'sdoc',         '0.4.0', group: :doc

group :development, :test do
  gem 'sqlite3',     '1.3.9'
  gem 'byebug',      '3.4.0'
  gem 'web-console', '2.0.0.beta3'
  gem 'spring',      '1.1.3'
end

group :test do
  gem 'minitest-reporters', '1.0.5'
  gem 'mini_backtrace',     '0.1.3'
  gem 'guard-minitest',     '2.3.1'
end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
end

运行heroku run rails console后的错误消息：

非常感谢任何帮助！

Answer 1

您拥有development群组中的宝石。如果您将其从该组中取出并将其放入主组中，请执行另一个bundle install，将其添加到存储库并重新部署，我认为它将全部正常工作。

Answer 2

我是Rails的新手并且也在阅读教程。我有同样的问题。经过多次观察和与经验丰富的Rails开发人员讨论后，这是答案。

根据你的日志文件查看第4行的bin / rails文件:(这是代码。第4行是发生错误的地方。）

#!/usr/bin/env ruby
begin
  spring_bin_path = File.expand_path('../spring', __FILE__)
  load spring_bin_path
rescue LoadError => e
  raise unless e.message.end_with? spring_bin_path, 'spring/binstub'
end
APP_PATH = File.expand_path('../../config/application', __FILE__)
require_relative '../config/boot'
require 'rails/commands'

如果删除第6行，则不会引发错误，也不会加载spring。这是以前版本的bin / rails代码所做的，并且一切正常。我不知道它是Rails还是Cloud9，或者是什么产生了这段代码，但最近几天发生了变化，毫无疑问。

注意：确保将spring gem留在gemfile的开发组中。我不会将spring gem移动到gemfile中的主要组，因为不管我的知识有多少，Spring都不应该在生产中运行。

希望这有帮助。

Answer 3

我和spring人一起买了一张票

https://github.com/rails/spring/issues/450

我怀疑这与spring gem版本1.4.4

有关

Answer 4

在Spring团队提出更好的解决方案之前，我修补了bin/rails并设置了一个Heroku环境变量，以避免在生产中加载Spring：

heroku config:set DISABLE_SPRING=1

<强>仓/轨道：

#!/usr/bin/env ruby
unless ENV["DISABLE_SPRING"]
  begin
    spring_bin_path = File.expand_path('../spring', __FILE__)
    load spring_bin_path
  rescue LoadError => e
    raise unless e.message.end_with? spring_bin_path, 'spring/binstub'
  end
end
APP_PATH = File.expand_path('../../config/application',  __FILE__)
require_relative '../config/boot'
require 'rails/commands'

根据他们的文档，

DISABLE_SPRING为the recommended environment variable。

Answer 5

最新版本的弹簧是1.4.2。您可能希望以该版本而不是旧版本执行spring。

Heroku不认识春天＆＃39;宝石，即使它在Gemfile中列出
