NPM的全称是Node Package Manager,可以通过npm命令对node.js安装扩展模块,已完成更加复杂的开发,类似于centos下的yum命令
用法如下: npm install mysql (扩展mysql为例子)
npm http GET https://registry.npmjs.org/mysql
npm http 304 https://registry.npmjs.org/mysql
npm http GET https://registry.npmjs.org/require-all/0.0.3
npm http GET https://registry.npmjs.org/bignumber.js/1.0.1
npm http 304 https://registry.npmjs.org/require-all/0.0.3
npm http 304 https://registry.npmjs.org/bignumber.js/1.0.1
mysql@2.0.0-alpha8 node_modules\mysql
├── require-all@0.0.3
└── bignumber.js@1.0.1
表示mysql的模块已经下载好了,我的机器上默认的路径为 C:\Users\lile\node_modules\mysql ,将这个文件夹复制到webstorm 创建的node_modules下,就可以用这个扩展模块操作mysql数据库了
