沒了

您好！
我在做规则节点二次开发尝试，按照文档 Clone [email protected]:blackstar-baba/rule-node-examples-ui-ngx.git并切换到customer后，执行到 yarn run build 时报以下错误，官网的rule-node-examples-ui-ngx前几天也报同样错误，不过昨天修正了，您能否给些提示？非常感谢您的无私奉献！
yarn run v1.22.17

请问下这个报错怎么解决？

怎么连接MQTT.fx到http://blackstar-baba.com:9090/devices，想试试遥测数据

我在按照您写的文档创建组件时，程序报了两处错误，我不太清楚是哪里的问题
但是好像是babylonjs的库并没有引用成功，因为报错的部位是babylonjs的库函数部位
我安装了npm，也安装了yarn，并且yarn是在全局下安装的，Thingsboard的环境是ubuntu
