ng 构建失败并显示“您正在运行 Node.js 的 v8.11.3 版本，Angular CLI 8.0+ 不支持该版本。”

Question

我试图重现 spring/angular [tutorial][1]，但我无法运行 ng build 命令（通过 maven）。 我多次重新安装了 nodejs msi 安装程序，但它仍然说我的节点版本不受支持。 我对 angular 很陌生，不知道在这里做什么。 我发现很多相关问题可以通过 npm 缓存清理和 npm 更新来解决，但它并没有解决我的问题

windows 10（64位）

me> npm -v
6.9.0

me>node -v
v10.16.3

您正在使用 maven-fronted-plugin 安装和执行 node/npm 的本地分发，而不是全局安装的常规二进制文件。 有关 maven pom.Z0F635D0E0F3874FFF8B581C132E6C7A7 文件中所需节点版本的配置，请参见https://github.com/eirslett/frontend-maven-plugin 。
