更新angular，webpack和打字稿后，我遇到了奇怪的错误。 知道我可能缺少什么吗？
当我使用npm start运行应用程序时，出现以下错误：
[at-loader] Cannot find type definition file for 'hammerjs'.
[at-loader] Cannot find type definition file for 'node'.
[at-loader] src\app\app.component.ts:26:14
Cannot find name 'require'.
[at-loader] src\app\app.component.ts:30:15
Cannot find name 'require'.

这似乎更可能是typings.json文件中的版本问题。你能试试以下吗？
typings install dt~node --save
typings install dt~core-js --save
typings install dt~hammerjs --save

它可能是一个不匹配的ts节点版本，其中更新ts节点应该修复它found here或者它可能是不正确的tsconfig.json found here
如果这些不起作用，您可能会发现一些有用的链接：

尝试在Visual Studio的“程序包管理器”控制台中运行@ types / node程序包，以重新导入它：
npm i -D @types/node
如果必须使用特定版本，则可以指定：
npm i -D @types/node@6.0.10

就我而言，在执行npm更新后，出现此错误。通过重新启动我的节点服务器，它消失了：
npm start
答案 4 :(得分：0)
您可能需要从@types安装缺少的类型 它已经存在，但仍然出现此错误，请继续执行步骤2
如果您使用的是ts-loader，则需要对其进行升级
在某些情况下，是Webpack版本控制导致此错误；升级到Webpack版本，ts-node，awesome-typescript-loader等将为您解决
如果您已使用core-js升级其版本
通常，所有解决方案都各不相同，但是它的节点模块版本需要您多花一点时间！尝试更多
祝一切顺利！
