找不到“节点”的类型定义文件

Question

更新 angular、webpack 和 typescript 后出现奇怪的错误。 知道我可能会错过什么吗？

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'.

Answer 1

尝试通过在 Visual Studio 的包管理器控制台中运行来重新导入 @types/node 包：

npm i -D @types/node

如果必须使用特定版本，您可以指定：

npm i -D @types/node@6.0.10

Answer 2

这似乎更可能是typings.json文件中的版本问题。 您可以尝试以下方法吗？

typings install dt~node --save
typings install dt~core-js --save
typings install dt~hammerjs --save

Answer 3

它可能是一个不匹配的 ts-node 版本，其中更新 ts-node 应该修复它在这里找到，或者它可能是一个不正确的 tsconfig.json 在这里找到

如果这些不起作用，这里有一些链接，您可能会觉得有用：

Answer 4

就我而言，在执行 npm update 后，我收到此错误。 它通过重新启动我的节点服务器消失了：

npm start

Answer 5

您可能需要应用多种解决方案来解决此问题！

第1步

您可能需要从已经存在的 @types 中安装缺少的类型，但仍然出现此错误，请继续执行第 2 步

第2步

如果您使用的是 ts-loader，则需要升级它

第 3 步（并非适用于所有人）

在某些情况下，导致此错误的是 webpack 版本控制； 升级到 webpack 版本，ts-node，awesome-typescript-loader 等会为你解决

第 4 步（仅限 Angular）

如果你使用过 core-js 升级它的版本

一般来说，解决方案因人而异，但是它的节点模块版本您需要稍微玩一下！ 这更像是一次次尝试

祝一切顺利！
