找不到redis_store的缓存存储适配器

Question

我有Rails 3.1.3应用程序并尝试将gem"redis"插入其中.

我在gemfile中添加了以下gem:

宝石"redis-store"

在本文之后,我将以下代码添加到environment/development.rb:

config.gem "redis-store", :lib => "redis-store"
require "redis-store" # HACK
config.cache_store = :redis_store

应用程序无法启动,向cache_store抱怨:

/gems/activesupport-3.1.3/lib/active_support/cache.rb:65:in`lookup_store':找不到redis_store的缓存存储适配器(没有要加载的文件 - active_support/cache/redis_store)(RuntimeError).

我已经弄清楚了,包括gem"redis-rails"而不是"redis-store",但我得到了另一个错误:

/Users/AntonAL/.rvm/gems/ree-1.8.7-2011.03@global/gems/bundler-1.0.21/lib/bundler/rubygems_integration.rb:143:in"gem":redis-store不属于捆绑.将其添加到Gemfile.(宝石:: LoadError)

保持他们两个......

gem 'redis-store'
gem 'redis-rails'

...给出了另一个错误

请帮忙!

Answer 1

尝试

gem 'redis-store', '~> 1.0.0'

Answer 2

仅供参考我...在我将所有以下内容添加到我的Gemfile之前,我遇到了类似的问题.我正在运行Rails 3.2.3.

    gem 'redis'
    gem 'redis-store'
    gem 'redis-rails'

Answer 3

这就是你所需要的:

gem 'redis-rails' # Will install several other redis-* gems

(参见:https://github.com/redis-store/redis-rails)

Answer 4

我在 Rails 5.2 应用程序中遇到了类似的问题。

原来问题出在production.rb. Rails guides 指示使用config.cache_store = :redis_cache_store, { url: ENV['REDIS_URL'] }，但这是不正确的。

什么对我有用：

在 Gemfile 中

gem 'redis-rails', '~> 5'

在 config/environments/production.rb

config.cache_store = :redis_store, ENV['REDIS_URL']
