To catch the error and print it to the console:
捕获错误并将其打印到控制台:
redisClient.on('error', function (err) {
console.log('Error ' + err);
});
You may also want to add handling of different forms of errors in later as well.
您可能还希望稍后添加对不同形式的错误的处理。

You have an error in a callback-function which is called by redis:
你在redis调用的回调函数中有一个错误:
// from https://github.com/mranney/node_redis/blob/master/index.js
if (command_obj && typeof command_obj.callback === "function") {
try {
command_obj.callback(err);
} catch (callback_err) {
// if a callback throws an exception, re-throw it on a new stack so the parser can keep going
process.nextTick(function () {
throw callback_err;
});
}
}
The real problem is that you cannot connect to mongodb and this throws an exception in a callback function invoked by redis-client.
真正的问题是你无法连接到mongodb,这会在redis-client调用的回调函数中引发异常。
