从提供的错误日志来看，你的Nacos启动失败的主要原因是在初始化ServerMemberManager时出现了问题具体地说，出现了一个java.net.UnknownHostException: jmenv.tbsite.net的异常这个异常表明Java程序无法找到主机jmenv.tbsite.net。问题可能是网络连接问题或配置问题。这里有一些可能的解决步骤：

步骤一：检查网络连接

首先确保你的机器能够连接到网络特别是如果Nacos配置中包含了jmenv.tbsite.net这个地址，确保你的机器可以访问到这个地址你可以使用ping命令或者浏览器来测试连接。

步骤二：检查配置

检查你的Nacos配置是否正确特别是与网络连接相关的配置，例如数据库连接、服务注册中心地址等确保这些配置是正确的并且指向正确的地址和端口。

步骤三：查看详细的日志信息

检查E:\java\nacos\logs\nacos.log文件来获取更详细的错误信息这可能有助于定位问题的具体原因。

步骤四：查看依赖问题

根据错误日志中的信息，看起来还有一些依赖没有正确地注入这可能涉及到某些Bean或服务的初始化问题你需要确保所有的依赖都已正确配置并可用。可能的话，查看是否有遗漏的依赖或者依赖版本不匹配的问题。

步骤五：重新构建项目或更新依赖

有时候问题可能出现在构建或依赖管理中你可以尝试重新构建项目或者更新项目依赖看看是否能解决问题。

总结和求助

如果以上步骤都不能解决问题，你可能需要更深入地查看代码和配置你也可以考虑在相关的开发者社区或论坛上发帖求助，提供详细的错误信息和日志，这样可能会得到更具体的帮助和建议。
