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

I tried to reproduce a spring/angular [tutorial][1], but I am not able to run the ng build command (by maven). I reinstalled the nodejs msi installer several times, but it still says that my nodes version is not supported. I am very new to angular and have no idea what to do here. I found a lot of related problems that could be solved by npm cache clean and npm update but it does not solve my problem

windows 10 (64bit)

me> npm -v
6.9.0

me>node -v
v10.16.3

You are using maven-fronted-plugin to install and execute a local distribution of node/npm, not the globally installed regular binaries. See https://github.com/eirslett/frontend-maven-plugin for the configuration of desired node version in the maven pom.xml file.
