当我运行命令zkCli时，我得到了以下输出：
Connecting to localhost:2181
Welcome to ZooKeeper!
JLine support is enabled
[zk: localhost:2181(CONNECTING) 0] ls /
KeeperErrorCode = ConnectionLoss for /
[zk: localhost:2181(CONNECTING) 1]我使用自制安装和服务启动zookeeper，它成功启动！zkServer status如下所示

homebrew安装路径是/usr/local/Cellar/zookeeper/3.5.7/bin echo打印Zookeeper version: 3.5.6-SNAPSHOT--1版本有问题吗？
现在我跟踪zookeeper.log并找出异常

请确保您的Zookeeper示例已启动并正在运行**，然后再尝试连接**它。
要检查Zookeeper的状态，请执行：
输出应类似于：
如果不起作用，请检查：
JAVA_HOME环境变量。您也可以运行export JAVA_HOME=$(/usr/libexec/java_home)（在macOS上）来确保它是正确的。lsof -i :2181、lsof -i :8080（通过分别更改clientPort和admin.serverPort，可以在zoo.cfg中配置两个端口）
