Your application should not try to connect to the localhost. 您的应用程序不应尝试连接到本地主机。 Instead, your initializer should fetch the env var ( REDIS_URL IIRC) and use it if it exists. 相反，您的初始化程序应获取env var（ REDIS_URL IIRC）并使用它（如果存在）。

Make sure you have Redis installed. 确保已安装Redis。 I know you said you got this on Heroku, but for example, if you were on a Mac and were using Homebrew, you could simply run brew install redis , and you'd be good to go. 我知道您说过您是在Heroku上获得的，但是例如，如果您使用Mac并使用Homebrew，则只需运行brew install redis ，就可以了。 (It fixed it for me, anyway.) （无论如何，它为我解决了问题。）
