Rails better_errors寶石服務器不啓動

Question

因爲我更喜歡better_errors寶石我無法使用命令欄服務器啓動我的服務器。我曾嘗試添加行到我的development.rb像BetterErrors::Middleware.allow_ip! "0.0.0.0/0"或BetterErrors::Middleware.allow_ip! ENV['TRUSTED_IP'] if ENV['TRUSTED_IP']，但它沒有奏效。 這是我的錯誤訊息，當我嘗試啓動服務器：

/home/jakub/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/better_errors-2.1.1/lib/better_errors/exception_extension.rb:6:in `caller_locations': stack level too deep (SystemStackError)

而且我的Gemfile：

source 'https://rubygems.org' 

gem 'rails',        '4.2.2' 
gem 'bcrypt',          '3.1.7' 
gem "paperclip",

    gem 'byebug',  '3.4.0' 
    gem 'web-console', '2.0.0.beta3' 
    gem 'spring',  '1.1.3'

    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 

Answer 1

這是在github的active issue自2014年一個解決辦法似乎是移動gem 'better_errors'出來的您的Gemfile中的development和testing組。

你也可以開始重新啓動spring手動這可能會解決你的問題：

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 

其他的事情你可以嘗試：

• 刪除您的Gemfile.lock，保持您的Gemfile不變，然後重新運行軟件包安裝。確保rails s不會在運行時運行。
• 刪除better_errors版本從您的Gemfile
