node.js安装后修改npm全局目录;关于node_global文件的修改

...

(1)

在nodejs文件下建立node_global和node_cache文件

(2)

npm root -g 查看npm安装的全局目录在里面
C:\Users\qinqinqin\AppData\Roaming\npm\node_modules

(3)

npm config set prefix "C:\Program Files\nodejs\node_global"
npm config set cache "C:\Program Files\nodejs\node_cache"

(4)

系统环境变量:
Path:%NODE_PATH%;C:\Program Files\nodejs\node_global;
NODE_PATH:C:\Program Files\nodejs\node_global

(5)

用户变量:
将C:\Users\qinqinqin\AppData\Roaming\npm(先查看自己的npm全局位置在哪)修改为
C:\Program Files\nodejs\node_global

(6)
关于修改全局环境之后的后遗症:
下载express依赖包失败

C:\Users\qinqinqin>npm install express -g
npm ERR! code EPERM
npm ERR! syscall mkdir

解决方案:win+x+a管理员模式下运行
尽量不要删除用户文件下的.npmrc文件,否则配置好的全局环境变量会修改回去
