Rails better_errors宝石服务器不启动

因为我更喜欢better_errors宝石我无法使用命令栏服务器启动我的服务器。我曾尝试添加行到我的development.rb像BetterErrors::Middleware.allow_ip! "0.0.0.0/0"或BetterErrors::Middleware.allow_ip! ENV['TRUSTED_IP'] if ENV['TRUSTED_IP']，但它没有奏效。这是我的错误讯息，当我尝试启动服务器：Rails better_errors宝石服务器不启动

这是在github的active issue自2014年一个解决办法似乎是移动gem 'better_errors'出来的您的Gemfile中的development和testing组。

你也可以开始重新启动spring手动这可能会解决你的问题：

cd /your/project 
spring stop 
... 
spring start 
...

在你的Gemfile：

source 'https://rubygems.org' 

gem 'rails', '4.2.2' 
gem 'bcrypt', '3.1.7' 
gem "paperclip", 
git: "git://github.com/thoughtbot/paperclip.git" 
gem 'better_errors', '~> 2.1.1' 

group :development, :test do 
    # ... 
end

其他的事情你可以尝试：

删除您的Gemfile.lock，保持您的Gemfile不变，然后重新运行软件包安装。确保rails s不会在运行时运行。
删除better_errors版本从您的Gemfile

是的，我删除了我的Gemfile better_errors现在服务器工作，是否有可能使服务器工作，这种宝石？ –

是的，你可以简单地把它放在其他宝石的下面，而不是使用gem'groups'。如果您仍在开发中，并且不在生产中为您的应用程序提供服务，那么这是一件合理的事情。 –
