前提电脑中已经安装过NodeJS, npm。现在需要进行升级操作。
1、查看当前的npm和NodeJs的版本:
C:UsersAdministrator>node -v
v4.4.3
C:UsersAdministrator>npm -version
2.15.1
2、升级npm:
C:UsersAdministrator>npm install npm -g
C:Program Files
odejs
ode_global
pm -> C:Program Files
odejs
ode_global
ode_modules
pmin
pm-cli.js
npm@4.5.0 C:Program Files
odejs
ode_global
ode_modules
pm
C:UsersAdministrator>npm -version
4.5.0
3、安装全局n模块:
C:UsersAdministrator>npm install -g n
npm ERR! code EBADPLATFORM
npm ERR! notsup Unsupported platform for n@2.1.7: wanted {"os":"!win32","arch":"

报错哦,那执行下面的命令:
C:UsersAdministrator>npm install -g n --force
npm WARN using --force I sure hope you know what you are doing.
