我已经开始学习vue js并试图运行这个HackerNews clone
我在Windows 8上安装了节点js，即节点v6.9.1和npm v3.10.8。
有两个问题
1）当我试图运行npm命令时，它就像 npm -v 一样，它给了我这样的输出
'CALL "C:\Program Files\nodejs\\node.exe" "C:\Program Files\nodejs\\node_modules
\npm\bin\npm-cli.js" prefix -g' is not recognized as an internal or external com
mand,
operable program or batch file.
3.10.8
2）当我尝试 npm run dev 时，会出现以下错误

这里我无法理解maven的用途：/
请解释我这个问题。
