TypeScript 2.0 从排除的文件中抛出错误? [英] TypeScript 2.0 throws errors from excluded files?

问题描述

我有一个基于 this 种子项目的 nodeJS 项目.它有两个 tsconfig.json 文件，如下所示:

I have a nodeJS project based on this seed project. It has two tsconfig.json files which look like this:

{
    "compilerOptions": {
        "target": "es6",
        "module": "system",
        "moduleResolution": "node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false
    },
    "exclude": [
        "../node_modules"
    ]
}

然而，尽管排除了 node_modules，我还是收到了很多错误，其中一些我已经在下面显示了.自从我开始使用新的 npm i @types/xyz 方法以来，就发生了这种情况.

however, despite the exclude node_modules, I get loads of errors, some of which I've shown below. This has occured since I started using the new npm i @types/xyz approach.

[0] node_modules/@types/core-js/index.d.ts(21,14): 错误 TS2300: 重复标识符PropertyKey".

推荐答案

我刚刚使用 anguler2 项目升级到 ts2.0 后遇到了这个问题.我现在使用 typings 并且有很多依赖项.其中至少包括@types，它复制了一些导入.但它们是必需的，我不能只删除文件夹/依赖项(就像其他人建议的那样).

I just ran into this issue after upgrading to ts2.0 with an anguler2 project. I'm using typings for now and have a lot of dependencies. At least on of them is including @types, which duplicates some of the imports. But they are required, I can't just delete the folder / dependency (like other have suggested).

在这里，我找到了一个对我有帮助的解决方案的指针:https://github.com/Microsoft/TypeScript/issues/11257

On here I found a pointer to the solution which helped me: https://github.com/Microsoft/TypeScript/issues/11257

来自 lucassp 的示例:

Sample from lucassp:

{
    "compilerOptions": {
        "target": "es6",
        "module": "commonjs",
        "moduleResolution": "node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false,
        "types": []
    },
    "exclude": [
        "../node_modules"
    ]
}

我只需将 "types": [] 添加到 tsconfig.json 文件中，这使得它不包含 @types 中的任何类型(因为它们目前都由类型管理).

I simply had to add "types": [] to the tsconfig.json file, which makes it include none of the types in @types (since all of them are managed by typings currently).

以下是编译器选项的说明来自文档:

Here's the description of the compiler option from the doc:

--types string[]
List of names of type definitions to include. See @types, –typeRoots and –types for more details.

微软似乎认为@types 是新的黑色打字稿定义导入.在这里阅读更多信息.

Microsoft seems to think that @types is the new black typescript definition imports. Read more info on this here.

最终我可能会迁移，但我会先让尘埃落定.

Eventually I might migrate, but I'll let the dust settle, first.
