我正在尝试让我的 Rails 应用程序使用 Sidekiq 处理后台作业，并将 Sidekiq 与 Heroku 上的 redis-to-go 连接起来。这是我的Procfile：
web: bundle exec puma -C config/puma.rb
worker: bundle exec -C config/sidekiq.yml
这是我的Sidekiq.rb初始化程序文件：
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
该REDIS_PROVIDER变量REDISTOGO_URL在 Heroku 中设置为。根据此处提供的说明，我还添加了一个初始化程序文件redis.rb。以下是内容：
uri = URI.parse(ENV["REDIS_PROVIDER"])
REDIS = Redis.new(:url => uri)
我收到以下错误，不知道如何解决。Heroku 也抛出了 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并从 gemfile 中删除了 redis gem，删除了 redis 初始化文件，应用程序不再崩溃。但是后台作业仍然无法正常工作，并且我在日志中收到这些错误：
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`
为什么系统不接受导致worker崩溃的config参数？
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 ''):
