我在安装了Apache的Ubuntu服务器上使用passenger

当我尝试加载带有redis的ruby应用程序时，我得到了这个错误

这就是我的resque_r.rb的样子（它位于config/initializers中）

从堆栈跟踪来看，在加载

config.ru

时似乎发生了错误

您的config.ru文件中似乎没有包含

resque/server

以下是我在一个项目中使用的配置：

require ::File.expand_path('../config/environment',  __FILE__)
require 'resque/server'

run Rack::URLMap.new \
  "/"       => DmWorkflow::Application,
  "/resque" => Resque::Server.new

另外，我不知道这是否对您有影响，但我在我的

Gemfile

中包含了以下内容：

gem 'resque'
gem 'resque-loner' 
gem 'resque-scheduler', ">= 2.0.0.h"

---

您正在运行旧版本的

resque

gem。

redis namespace

version

1.0.2

及更高版本上的

resque

新版本，但堆栈跟踪显示它加载了

redis namespace

v0.4.3

尝试运行

捆绑包更新

。如果版本仍然不正确，请将以下内容添加到

GEM文件中：

gem 'redis-namespace', '~> 1.0.2'

或者，您可以通过git安装边缘版本的
resque
：

gem 'resque', github: 'defunkt/resque'

我在服务器上安装了错误版本的redis。我没有使用apt-get-install-redis-server，而是手动安装了redis-server，解决了这个问题
 我不太明白你做了什么来修复这个问题，因为我相信这实际上是redis命名空间中的一个bug。请参阅。
请将您的GEM文件内容张贴在此处。看起来像是宝石冲突。@论文更新，谢谢！你在Ubuntu和Apache上有吗？它对我没有帮助，它在本地对我有效，但在服务器上无效。我正在heroku上部署。您是否在服务器上运行了
bundle install
？我尝试更改您的GEM文件中的设置，它安装redis 2.2.2（而不是3.0）并使用该设置。但这又给了我另一个错误。和这个人一样，我可以告诉他，我的redis服务器版本太旧了；我会更新它，看看它是否给我任何错误。尽快给你回电话！有趣的。。。我的
Gemfile.lock
也显示了
redis（2.2.2）
。但一切都很好。据rubygems.org称，
redis（3.0.0）
昨天刚刚发布。这可能是你的问题的一部分。实际上，我使用sudo apt get install redis server安装了一个旧的v。对于redis，这是一个很大的失误，我手动卸载并重新安装了redis，解决了问题！：）主要问题是我使用了错误的redis版本。我使用sudo apt get install redis server安装了一个旧的v。redis的。我卸载了它并手动安装了redis，解决了我遇到的问题。但是我确实用名称空间1.0.2更新了我的gemfile，谢谢你提供的信息！当@Narkoz编写gem'redis namespace'时，请将其放在gem文件中，“~>1.0.2”强制使用该版本的redis namespace可能会起到作用，但问题最终是由我发布的问题引起的。
gem 'redis-namespace', '~> 1.0.2'

gem 'resque', github: 'defunkt/resque'
