apache-kafka - Confluent CLI - 连接无法启动

Question

我为本地机器下载了 Confluent-7.0.0 安装它。尝试按照快速入门指南，我输入“confluent local services start”并收到此错误消息“错误：连接无法启动”不知道出了什么问题，即使是旧版本也每次都会发生。我正在使用 ubuntu 虚拟机。

Using CONFLUENT_CURRENT: /tmp/confluent.587467
Starting ZooKeeper
ZooKeeper is [UP]
Starting Kafka
Kafka is [UP]
Starting Schema Registry
Schema Registry is [UP]
Starting Kafka REST
Kafka REST is [UP]
Starting Connect
Error: Connect failed to start

当我直接运行 kafka connect 时，它能够启动服务，但有一些错误消息。
