Typescript编译器突然开始产生错误

我正在开发一个Angular 2项目，当我尝试运行打字稿编译器时，突然间我开始出现大量的错误。 任何人都可以请build议从哪里开始search？ 我没有明确地改变任何基本的东西，甚至当我从库中克隆一个新的副本，错误仍然存​​在。 错误如下：

Answer 1

看起来你有两个地方的节点types。

node_modules/@types/node/index.d.ts

分型/全局/节点/ index.d.ts

Answer 2

如前所述，你好像混合了@types（通过使用typescript2）与typings。 就像我升级到打字稿2.x. 我有完全相同的错误。 我通过简单地在tsconfig中的compilerOptions中添加types声明“ types": []来解决。 我在这里更详细地描述了这个： https : //stackoverflow.com/a/40627265/333150

这基本上不会包含@types位置的任何types，只能使用types声明。

Answer 3

删除typings.json文件将解决这个问题。

以前版本的Angular Quickstart项目包含此文件。 但是，当试图升级到最新版本的Angular时，我发现这个文件不再是Quickstart的一部分。 它在这个提交中被删除。 如果您最初基于您的项目的代码，查看Quickstart的更新是有帮助的。
