javascript - 找不到“hammerjs”的类型定义文件

问题描述

在尝试运行我的项目 ionic cordova run Android 时，它会显示错误：-

[13:07:43]  typescript error 
            Cannot find type definition file for 'hammerjs'. 

TypeError: Cannot read property 'replace' of null
    at Object.escapeHtml (D:\projects\hafele_latest\node_modules\@ionic\app-scripts\dist\util\helpers.js:253:10)

    at D:\projects\hafele_latest\node_modules\@ionic\app-scripts\dist\build.js:109:82

我已经添加了@types/hammerjs。我不认为这是一个定义错误。我认为这是应用程序脚本错误。

这对我有用

npm i @types/hammerjs
