Confusing "duplicate identifier" Typescript error message
提问by pitosalas
Why am I getting this and many more errors of this kind? I am adding a link to the repo as well as key code snippets below. I think I have a basic misunderstanding of how the dependency and "include" chaining works.
为什么我会收到此错误以及更多此类错误？我正在添加一个指向 repo 的链接以及下面的关键代码片段。我想我对依赖和“包含”链接的工作方式有一个基本的误解。

This is because of the combination of two things:
这是因为两件事的结合：
tsconfignot having anyfilessection. From http://www.typescriptlang.org/docs/handbook/tsconfig-json.htmlIf no "files" property is present in a tsconfig.json, the compiler defaults to including all files in the containing directory and subdirectories. When a "files" property is specified, only those files are included.
Including
typescriptas an npm dependency :node_modules/typescript/This means that all oftypescriptgets included .... there is an implicitly includedlib.d.tsin your project anyways (http://basarat.gitbook.io/typescript/content/docs/types/lib.d.ts.html) and its conflicting with the one that ships with the NPM version of typescript.
tsconfig没有任何files部分。来自http://www.typescriptlang.org/docs/handbook/tsconfig-json.html如果 tsconfig.json 中不存在“files”属性，则编译器默认包含包含目录和子目录中的所有文件。当指定了“files”属性时，只包含那些文件。
包含
typescript作为 npm 依赖项：node_modules/typescript/这意味着所有内容typescript都包含在内......lib.d.ts无论如何，您的项目中都隐式包含了一个（http://basarat.gitbook.io/typescript/content/docs/types/lib.d.ts .html) 及其与 NPM 版本的打字稿附带的冲突。
Fix
使固定
Either list filesor includeexplicitly https://basarat.gitbook.io/typescript/docs/project/files.html
列出files或include明确https://basarat.gitbook.io/typescript/docs/project/files.html

Update: Version 1.0 of Typings changed the output structure and the below answer relates to pre 1.0 version.
更新：Types 1.0 版更改了输出结构，以下答案与 1.0 版之前的版本有关。
If you are using Typings and exclude in your tsconfig.json, you may run into the issue of duplicate types and need something like the following:
如果您在 tsconfig.json 中使用 Typings 和 exclude，您可能会遇到重复类型的问题，并且需要类似以下内容：
{
"exclude": [
"typings/browser.d.ts",
"typings/browser",
"node_modules"
]
}
To simplify integration with TypeScript, two files - typings/main.d.ts and typings/browser.d.ts - are generated which reference all the typings installed in the project only one of which can be used at a time.
为了简化与 TypeScript 的集成，生成了两个文件——typings/main.d.ts 和typings/browser.d.ts，它们引用了项目中安装的所有typings，一次只能使用其中一个。
So depending on which version you need, you should exclude (or include) the "browser" or the "main" type files, but not both, as this is where the duplicates come from.
因此，根据您需要的版本，您应该排除（或包含）“浏览器”或“主”类型文件，但不能同时排除，因为这是重复项的来源。
This Typings issuediscusses it more.

If you have installed typings separately under typings folder
如果您在typings 文件夹下单独安装了typings
{
"exclude": [
"node_modules",
"typings"
]

Problem was solved by simply:
问题很简单地解决了：
- Deleting the
node_modulesfolder - Running
npm installto get all packages with correct versions
- 删除
node_modules文件夹 - 运行
npm install以获取具有正确版本的所有软件包
In my case, the problem occurred after changing Git branches, where a new branch was using a different set of node modules. The old branch was using TypeScript v1.8, the new one v2.0
就我而言，问题发生在更改 Git 分支之后，其中一个新分支使用了一组不同的节点模块。旧分支使用 TypeScript v1.8，新分支使用 v2.0

I just ran into this problem. When I ran npm start, I got a bunch of duplicate identifier errors.
我刚刚遇到了这个问题。当我运行时npm start，我收到了一堆重复的标识符错误。
SOLUTION:
解决方案：
From the project root folder run:
从项目根文件夹运行：
rm -r typings
typings install
npm start
and everything works fine.
一切正常。

You could also use the exclude option in tsconfig.json file like so:
您还可以在 tsconfig.json 文件中使用 exclude 选项，如下所示：
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"declaration": false,
"noImplicitAny": false,
"removeComments": true,
"noLib": false,
"emitDecoratorMetadata": true,
"experimentalDecorators": true
},
"exclude": [
"node_modules"
]
}

In my case I got the error as
在我的情况下，我得到了错误
node_modules/@types/es6-promise/index.d.ts(11,15): error TS2300: Duplicate identifier 'Promise'.
node_modules/@types/es6-promise/index.d.ts(11,15): 错误 TS2300: 重复标识符“承诺”。
And I had @types/es6-promiseon my package.json but my tsconfigwas already with target: "es6". So I guess there was a conflict with Promisewhen compiling.
我有@types/es6-promise我的 package.json 但我tsconfig已经有了target: "es6". 所以我猜Promise编译的时候有冲突。
Removing @types/es6-promisefrom my package.jsonfile solved the issue.
@types/es6-promise从我的package.json文件中删除解决了这个问题。

Using webpackI came across same error, just in case excluding the .d.tsfile in your tsconfig.jsonand node_modules solved my issue:
使用webpack我遇到了同样的错误，以防万一排除tsconfig.json和 node_modules 中的.d.ts文件解决了我的问题：
"exclude": [
"node_modules",
"typings/main",
"typings/main.d.ts",
"typings/index.d.ts"
]

I had this issue caused by having an unexpected folder on disk (jspm_packages, no longer being used) which was not tracked by source control (and hidden from my IDE). This had a duplicate install of TypeScript in it, which caused the issues.
我遇到了这个问题，因为磁盘上有一个意外的文件夹（jspm_packages不再使用），它没有被源代码管理跟踪（并且从我的 IDE 中隐藏）。这其中重复安装了 TypeScript，从而导致了问题。
Bit of an edge case but leaving an answer here just in case someone else is hunting for this solution.
有点边缘情况，但在这里留下一个答案，以防其他人正在寻找这个解决方案。
