You need to install @types/jquery and remove all the declare var
related to jQuery: 您需要安装@ types / jquery并删除所有与jQuery相关的
declare var
变量:
npm install @types/jquery --save
If you are also using webpack to build static files, you'll need this plugin: 如果您还使用webpack构建静态文件,则需要此插件:
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery"
}),
