After installing grunt with the command npm install -g grunt-cli npm install -g grunt
Run the command grunt -v or grunt and it keeps prompting that 'grunt' is not an internal or external command, nor is it an operable program...

This is my environment variable configuration

Answer 1

Cannot be installed globally grunt 值要安装 grunt-cli就可以了，然后在 %AppData%Roamingnpm 会生成一个 grunt.cmdIt means the installation is successful.

Answer 2

Guess: pathThe semicolon in the path won’t be a Chinese semicolon, right?

Answer 3

Open

C:\Users（用户）\你的用户名\.npmrc 

Change this file
to

prefix=C:\Program Files\nodejs\node_modules
cache=C:\Program Files\nodejs\node_cache
registry = http://registry.cnpmjs.org

The first two are the two folders under the node installation path
