Heroku错误：ArgumentError:无效的uri方案''；

我正试图让我的Rails应用程序处理Sidekiq的后台工作，并将Sidekiq与redis连接起来，以便在Heroku上运行。这是我的

程序文件

：

web: bundle exec puma -C config/puma.rb
worker: bundle exec -C config/sidekiq.yml

下面是我的

Sidekiq.rb

initializer文件：

require 'sidekiq'

Sidekiq.configure_client do |config|  
  config.redis = { url: ENV['REDIS_PROVIDER'] }
end 

Sidekiq.configure_client do |config|  
   config.redis = { url: ENV['REDIS_PROVIDER'] }
end

Heroku中的

REDIS\u PROVIDER

变量设置为

REDISTOGO\u URL

。根据提供的说明，我还添加了一个初始化器文件

redis.rb

。内容如下:

uri = URI.parse(ENV["REDIS_PROVIDER"])
REDIS = Redis.new(:url => uri)

我收到以下错误，不确定如何解决。Heroku也抛出了一个H10错误

[3] ! Unable to load application: ArgumentError: invalid uri scheme '

/app/vendor/bundle/ruby/2.2.0/gems/redis-3.3.0/lib/redis/client.rb:416:in `_parse_options': invalid uri scheme '' (ArgumentError) 

更新：

我在Heroku上回滚到以前的版本，从gemfile中删除redis gem，删除redis Initializer文件，应用程序不再崩溃。但是，后台作业仍然不起作用，我在日志中发现以下错误：

heroku/worker.1:  Starting process with command `bundle exec -C config/sidekiq.yml`
heroku/worker.1:  State changed from starting to up
app/worker.1:  bundler: command not found: -C 
heroku/worker.1:  Process exited with status 127 
heroku/worker.1:  State changed from up to crashed 
app/worker.1:  Install missing gem executables with `bundle install` 

为什么系统不接受配置参数导致工作进程崩溃

无效uri方案的错误仍然存在：

app/web.1:  Completed 500 Internal Server Error in 303ms (ActiveRecord: 0.0ms) 
app/web.1:  ArgumentError (invalid uri scheme ''):

通过将redis.rb和sidekiq.rb中的redis URL引用更改为相同的redis Cloud ENV变量，我能够纠正我的应用程序（Rails 6，Ruby 2.7.2）中失败的Heroku部署和

TL；博士如果您在本地使用Sidekiq/Redis有问题，请将Redis URI定义为

Sidekiq\u Redis\u URL=redis://localhost:6379

文档说Sidekiq将尝试连接到

localhost:6379

，这可能是真的，但他们缺少一个小细节。URI方案不是

http

或

https

，而是

redis

在我的配置中，我试图传递一个在.env文件中设置的具体SIDEKIQ_REDIS_URL

Sidekiq.configure_server do |config|
    config.redis = { url: ENV.fetch('SIDEKIQ_REDIS_URL'), size: 12, network_timeout: 5 }
end

现在，如果您不在.env中声明

SIDEKIQ\u REDIS\u URL

，它当然不会工作。此外，即使添加默认URI，也会失败：

SIDEKIQ\u REDIS\u URL=localhost:6379

它会抱怨URI方案

我再次查看了文档，我相信我正确地使用了它。它说：

将REDIS\u提供者env var设置为包含REDIS服务器url的env var的名称。（RedisGreen示例：设置REDIS_PROVIDER=RedisGreen_URL，Sidekiq将在连接到REDIS时使用RedisGreen_URL env变量的值。）

REDIS_PROVIDER变量设置为heroku中的REDISTOGO_URL变量，该变量包含

redis://redistogo:xxxxx

。我写了Sidekiq；你的信心放错地方了REDIS_PROVIDER的值不应该是URL，因此

URI.parse（ENV['REDIS_PROVIDER']）

是错误的。REDIS_PROVIDER的值应该是“REDISTOGO_URL”。您可以完全删除sidekiq.rb初始值设定项。如果REDIS_PROVIDER设置正确，Sidekiq将自动解决所有问题。嗨，迈克，谢谢你的帮助。正如我在更新中提到的，我删除了redis初始值设定项文件，因为我读到它不是必需的。我在上一条评论中解释说，REDIS_PROVIDER变量的设置与您在上一条评论中指定的完全一致。我再次查看了文档，我相信我使用的是正确的。它说：
