So unfortunately I can't figure out where the error is pointing to as none of the code is my stuff and mainly the trace consists of code from the default gems. The one thing that I can see that I have added in there is the bootstrap gem, but the same thing happens even if I take that out.
所以不幸的是我无法弄清楚错误指向的位置,因为没有代码是我的东西,主要是跟踪由默认宝石的代码组成。我可以看到我添加的一件事是引导宝石,但即使我把它拿出来也会发生同样的事情。

It looks like you have incorrect redis connection (or setup)
看起来你有不正确的redis连接(或设置)
To debug it:
要调试它:
1) Debug redis connection with in rails console. Using Redis from your application
1)使用rails控制台调试redis连接。从您的应用程序中使用Redis
>> require 'rubygems'
=> false
>> require 'redis'
=> true
>> r = Redis.new
=> #<Redis client v2.2.1 connected to redis://127.0.0.1:6379/0 (Redis v2.3.8)>
>> r.ping
=> "PONG"
>> r.set('foo','bar')
=> "OK"
>> r.get('foo')
=> "bar"
2) Debug RedisStore
2)调试RedisStore
RedisStore.new("localhost:6379/0/cache", expires_in: 90.minutes)
3) If the command passed, set up this config for your app like it's described in gem redis-rails
3)如果命令通过,请为您的应用程序设置此配置,就像在gem redis-rails中描述的那样
# config/application.rb
config.cache_store = :redis_store, "redis://localhost:6379/0/cache", { expires_in: 90.minutes }
4) Play with configuration a little to establish successful connection to redis (And don't forget about different environment configs in production!!!)
4)使用配置稍微建立与redis的成功连接(并且不要忘记生产中的不同环境配置!)
5) Commit changes, redeploy.
5)提交更改,重新部署。

You're trying to compile assets in the production environment, but you're also on your dev machine. Are you sure you've configured a production environment in all of your config files? Look in config/cable.yml and config/redis.yml if they exist.
您正在尝试在生产环境中编译资产,但您也在开发计算机上。您确定已在所有配置文件中配置了生产环境吗?查看config / cable.yml和config / redis.yml(如果存在)。
Alternatively, a good way to compile assets in the development environment is:
或者,在开发环境中编译资产的好方法是:
RAILS_ENV=development bundle exec rake assets:precompile
However, after doing this, Rails will use these compiled assets in development instead of your assets in app/assets. Eventually, you'll also want to run RAILS_ENV=development bundle exec rake assets:clobber or rm -rf public/assets to clear your development environment of these compiled assets.
但是,执行此操作后,Rails将在开发中使用这些编译的资产,而不是app / assets中的资产。最后,您还需要运行RAILS_ENV =开发包exec rake资产:clobber或rm -rf public / assets以清除这些编译资产的开发环境。

So not sure what the problem was, but i updated ruby, rails and all my gems and that got rid of the problem. So thinking it was a compatibility issue with version mismatch somewhere
所以不确定问题是什么,但我更新了ruby,rails和我所有的宝石,并解决了这个问题。所以认为这是版本不匹配的兼容性问题
