如何安装node-sass模块以在项目中运行？我收到错误消息“找不到模块'sass'”

Question

node-sass模块在我的package.json中描述为devDepedencies部分。

但是当我运行npm run prod时，我得到一个错误

    Error: Cannot find module 'sass'
        at Function.Module._resolveFilename (module.js:538:15)
        at Function.Module._load (module.js:468:25)

    npm ERR! Exit status 1
    npm ERR! 
    npm ERR! Failed at the @ production script.
    npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

试图执行清洁命令

    rm -rf node_modules &&
    rm package-lock.json
    npm cache verify
    npm cache clear --force &&
    npm run prod

但错误仍然存​​在

请帮忙。
