webpack 打包 Error: Cannot find module ‘less‘错误解决办法

完整的错误信息

ERROR in ./src/index.less (../node_modules/css-loader/dist/cjs.js!../node_modules/less-loader/dist/cjs.js!./src/index.less)
Module build failed (from ../node_modules/less-loader/dist/cjs.js):
Error: Cannot find module 'less'
           

检测自己的配置发现安装了less

安装的命令是

npm i less-loader -D
           

多次安装无效，换了一个命令

npm install less --save-dev
           

打包成功
