报错是这一句，安装 Node 失败：
java.lang.IllegalStateException: Failed to install Node
你看哦，log里提到了几个目录：
D:\temp\untitled18.jmix\screen-designer\node_modules
C:\Users\Administrator.vaadin\node
你看看文件夹都存在吗？
还有，程序尝试解压 C:\Users\Administrator.vaadin\node-v18.14.1-win-x64.zip ，也检查一下文件存在吗
node 已安装，只是版本是18.17 比提示的高
log中目录和文件都存在
C:\Users\Administrator.vaadin\node-v18.14.1-win-x64.zip这个目录文件也有
找到原因：node-v18.14.1-win-x64.zip 默认下载的压缩包有问题，压缩文件打开错误，重新下载放到.vaadin目录，界面出现，问题解决，谢谢。
