我需要一些帮助。

在我输入npm run build到我的Windows 10终端后，我收到以下错误：

'imagemin'不被识别为内部或外部命令，可操作程序或批处理文件。错误的ERR！代码ELIFECYCLE npm ERR！错误1 npm ERR！ [email protected] imagemin：

这是我的package.json文件

Answer 1

您没有安装imagemin软件包。

npm install imagemin --save

Answer 2

安装imagemin-cli并在"imagemin": "imagemin img/ --out-dir=dist/img"中像package.json一样使用它
