我有/config/initializers/redis.rb：

if Rails.env == "development"
  $redis = Redis.new(:host => 'localhost', :port => 6379)
elsif Rails.env == "test"
  $redis = Redis.new(:host => 'localhost', :port => 6379)
elsif Rails.env == "production"
  uri = URI.parse(ENV["REDISTOGO_URL"])
  REDIS = Redis.new(:host => uri.host, :port => uri.port, :password => uri.password)
end

显然，当我在本地运行应用程序时，REDISTOGO_URL是未定义的。

鉴于此，我该如何rails server -e production工作？

我需要在本地访问生产环境才能运行RAILS_ENV=production bundle exec rake assets:precompile.

目前，这会产生以下错误：

$ RAILS_ENV=production bundle exec rake assets:precompile --trace
** Invoke assets:precompile (first_time)
** Execute assets:precompile
/Users/steven/.rvm/rubies/ruby-1.9.3-p286/bin/ruby /Users/steven/.rvm/gems/ruby-1.9.3-p286/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets --trace

正如 bimsapi 在评论中提到的那样，一种简单的方法是运行

export REDISTOGO_URL='redis://localhost:6379'

在您的命令行中，也许在您重新启动时将其放入您的 shell 配置中？

另一种方法是如果它不存在就创建它：

例如/

ENV["REDISTOGO_URL"] ||= 'redis://localhost:6379' if Rails.env.production?

此外，您的条件逻辑在上面的查询中看起来有点不合适。

您可能只想完全放弃条件并改为这样做？：

ENV["REDISTOGO_URL"] ||= 'redis://localhost:6379'
uri = URI.parse(ENV["REDISTOGO_URL"])
$redis = REDIS = Redis.new(:host => uri.host, :port => uri.port, :password => uri.password)

HTH？
