前几天项目运行得好好的，今天怎么启动就是报

折腾了一天，从重新获取代码，重新mvn clean install，按网上的方案将bootstrap.yml的配置格式改为nacos.cmdb.xxx等，反复测试，问题依然坚挺。

最后采用了清除已install的文件，所有重新来安装，这样终于解决了这个不知所以然的问题，其中如下第7点也是不知所以然的问题

1. 删除C:\Users\Administrator\.m2

2. 删除C:\Users\Administrator\nacos

3. 删除pigx，重新git clone

4. cmd命令 mvn clean install -Dmaven.test.skip=true

5. idea 打开项目

6. 修改pigx/pigx-register/src/main/resources/bootstrap.yml

7. 启动 PigxNacosApplication， --消息显示启动成功，但

  浏览器访问 http://127.0.0.1:8848/nacos  出现如下错误

  Whitelabel Error Page

8. 在idea的 Terminal 里 执行

  mvn clean install -Dmaven.test.skip=true

9. 再次启动 PigxNacosApplication， --消息显示启动成功

10.浏览器访问 http://127.0.0.1:8848/nacos

  终于出现了 期待已久 的nacos界面
