一.n stable 报错

'n' is not recognized as an internal or external command,
operable program or batch file.

'n' 不是内部或外部命令,也不是可运行的程序
或批处理文件。

 解决方法:

在GitHub官网,搜索gnvm,下载

git地址



放在node.js的安装目录下
然后打开cmd命令行窗口,输入:gnvm update latest,等待更新。
当然也可以直接覆盖.

二.命令行更新node版本
1.更新node.js版本命令:

npm install -g n

2.升级node.js到最新稳定版

n stable

遇到的错误:
1 、
D:\webpack>npm install -g n

解决方案
npm install -g n --force或-f:强制重新安装

2、
D:\webpack>npm install webpack –save-dev

解决方案:
出现问题是因为:package.json中已经有webpack了,换个名字就行了
