使用 Nodejs-demo 的 producter 时弹出这个错误。检查过 node-kafka 模块，确实是有 sasl_ssl 这个 enum value 的。改成其它值，也同样报错。

[dongeforever]

改成PLAINTEXT试一下呢；
如果PLAINTEXT可以，则说明librdkafka环境安装有问题：node-kafka模块是依赖librdkafka模块的；检查下librdkafka的版本；
如果PLAINTEXT也不可以，则node-kafka本身就有问题，建议重新安装一下；

[clChenLiang]

好的，谢谢，振东哥

[clChenLiang]

最终解决的方案：仅限于 Mac 系统
安装 brew ，更新 openssl 。后重新 npm install node-rdkafka.即可。
原因，Mac 中的 ssl 版本可能比 librdkafka 的版本低，所以需要更新一下。

以上代码运行是，producer.on("ready")方法不进入也不执行，程序一会就执行退出，请帮忙指正下。谢谢。

@scheng2013 配置不正确吧；加入Kafka用户交流群，参考群公告里面的资料呢

[johnnychq]

遇到同样问题，centos， 请kafka用户交流群号码是多少呢？ @dongeforever

[johnnychq]

@clChenLiang 请问，问题最终解决了吗
