1. 如果nacos下载完成后直接启动会报错如下错误

解决方法：打开你nacos文件找到bin文件下得startup.cmd文件打开

把set MODE=”cluster”修改为set MODE=”standalone” （cluster为集群启动 standalone为单机启动）（rem是注释得意思）

如下：

  1. 再次启动 会报如下错误：

Exception encountered during context initialization – cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘user’: Unsatisfied dependency expressed through field ‘jwtTokenManager’;

解决方法 打开你nacos文件找到conf文件下得application.properties 打开

找到 nacos.core.auth.plugin.nacos.token.secret.key= 在 后面加上 密钥

SecretKey012345678901234567890123456789012345678901234567890123456789

因为nacos 2.2.0.1版本后 默认得key值为空，需要手动加上

如下：

  1. 添加完成后 重启nacos 启动成功

成功解决，希望这篇文章对你们有所帮助
