typescript：error TS2693：'Promise'只引用一个类型，但在这里被用作值

时间：2017-03-30 13:22:01

标签： javascript typescript promise

我正在尝试使用Typescript作为我的AWS Lambda，我在使用promises时遇到以下错误。

error TS2693: 'Promise' only refers to a type, but is being used as a value here.

我尝试在代码中使用以下变体

使用Promise构造函数

responsePromise = new Promise((resolve, reject) => {
                    return reject(new Error(`missing is needed data`))
                })

使用Promise.reject 

responsePromise = Promise.reject(new Error(`Unsupported method "${request.httpMethod}"`));

版本

以下是我的开发依赖项中的版本：

"typescript": "^2.2.2"
"@types/aws-lambda": "0.0.9",
"@types/core-js": "^0.9.40",
"@types/node": "^7.0.12",

tsconfig.json的内容

        // "typeRoots" : ["./typings", "./node_modules/@types"],
        "target": "es5",

    ],
    "exclude": [
        "node_modules",
        "**/*.spec.ts"
    ]
}

我正在使用具有以下配置的grunt-ts来运行ts任务。

ts: {
            app: {
                tsconfig: {
                    tsconfig: "./tsconfig.json",
                    ignoreSettings: true
                }
            },
...

我尝试了I get: [ts] 'Promise' only refers to a type, but is being used as a value here中提到的解决方案，但没有运气。

答案 0 :(得分：109)

我对aws-sdk遇到了同样的问题，我使用"target": "es2015"解决了这个问题。这是我的tsconfig.json文件。

{
    "compilerOptions": {
        "outDir": "./dist/",
        "sourceMap": false,
        "noImplicitAny": false,
        "module": "commonjs",
        "target": "es2015"
    },
    "include": [
        "src/**/*"
    ],
    "exclude": [
        "node_modules",
        "**/*.spec.ts"
    ]
}

答案 1 :(得分：74)

今天遇到同样的错误并用以下方法解决：

npm i --save-dev  @types/es6-promise

<强>更新

添加：

import {Promise} from 'es6-promise'

答案 2 :(得分：32)

我通过在tsconfig.json文件中添加以下代码来解决这个问题。

"lib": [
    "ES5",
    "ES2015",
    "DOM",
    "ScriptHost"]

答案 3 :(得分：18)

通过更改compilerOptions中的目标来解决。

{
"compilerOptions": {
    "module": "es2015",
    "target": "es2015",
    "lib": [
        "es2016",
        "dom"
    ],
    "moduleResolution": "node",
    "noImplicitAny": false,
    "sourceMap": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "outDir": "./public/js/app"
},
"exclude": [
    "node_modules",
    "public/js",
    "assets/app/polyfills.ts"
],
"angularCompilerOptions": {
    "skipMetadataEmit": true
}
}

答案 4 :(得分：10)

这是我的提示。使用vscode 1.21.1（在MAC上）进行测试

将以下配置添加到 tsconfig.json 

"lib": [
"es2016",
"dom"
]

成 的 compilerOptions

重启IDE（需要执行此操作：D）

答案 5 :(得分：7)

将以下行添加到文件中引发错误。这应解决问题

declare var Promise: any;

答案 6 :(得分：4)

最后tsc开始工作没有任何错误。但是有多重变化。感谢Sandro Keil，Pointy＆amp; unional

  • 删除了dt~aws-lambda
  • 删除了noEmit，声明
    • 等选项
  • 修改了Gruntfile并删除了ignoreSettings

tsconfig.json

    "compileOnSave": true,
    "compilerOptions": {
        "module": "commonjs",

Gruntfile.js 

ts: {
            app: {
                tsconfig: {
                    tsconfig: "./tsconfig.json"
                }
            },
...

答案 7 :(得分：4)

与打字稿和aws-sdk有同样的问题。解决方法是将目标更改为es6。

我的完整tsconfig.json文件：

{
        compilerOptions: {
                outDir: ./dist/,
                sourceMap: true,
                noImplicitAny: true,
                module: commonjs,
                target: es6,
                jsx: react,
                allowJs: true
        },
        include: [
                ./src/**/*
    ]
}

答案 8 :(得分：3)

我遇到了这个错误，但是我使用此命令解决了，我的ts文件名为promises-fs.ts：

tsc promises-fs.ts --target es6 && node promises-fs.js

错误消失了

这里没有一个上升的答案对我有用。这是一个有保证的合理解决方案。把它放在使用Promise ...

declare const Promise: any;

我摆脱了index.ts中具有这些组合属性的相同错误：

在tsconfig.json中：

  "compilerOptions": {
    "target": "ES6"

在package.json中：

  "main": "index.ts",
  "scripts": {
    "start": "tsc -p tsconfig.json && node index.js"

好吧，这可能是违反直觉的，但是我解决了将esnext添加到lib的问题。 

{
  "compilerOptions": {
    "lib": [
        "esnext"
    ],
    "target": "es5",
  }
}

编译器建议的FIX是

  

尝试将lib编译器选项更改为es2015或更高版本。

Core-js对我不起作用，因为它引起了其他问题，但是，只需安装最新版本的npm i @types/es6-promise --save-dev即可解决问题。对我来说问题源于编译使用rxjs的sdk。这是我得到的错误：

`node_modules/rxjs/Observable.d.ts(59,60): error TS2693: Promise only refers to a type, but is being used as a value here.`

如果您在项目中使用DefinitelyTyped存储库，则可能遇到this recent issue。

您可能使用的一个不错的解决方法（除了等待定义文件的更新版本或重构您的TS代码之外）是为core-js类型指定显式版本+构建，而不是让Visual Studio选择最新的/最近的一个。我发现一个似乎不受此问题的影响（至少在我的情况下），您可以使用它替换 package.jso n文件中的以下行：

  "scripts": {
    "postinstall": "typings install dt~core-js --global"
  }

使用以下内容：

  "scripts": {
    "postinstall": "typings install dt~core-js@0.9.7+20161130133742 --global"
  }

这解决了我的问题。但是，强烈建议在问题发布后立即删除显式版本+构建引用。

我正在使用"promise-polyfill"库，这可能是我问题的原因。

我将此导入添加到文件顶部：

import {Promise} from 'es6-promise';

答案 16 :(得分：0)

npm i --save-dev @ types / es6-promise

启动命令后，您最好检查tsconfig.json，确保＆＃34; target＆＃34;必须伟大而不是＆＃34; es6＆＃34;。也许tsc还不支持es5。

花了很多时间试图解决这个问题。我在这里或其他地方提供的任何解决方案都没有运气。

但后来发现它并不仅仅是解决问题。但是你还需要重新启动VSCODE才能生效。

答案 18 :(得分：0)

只需将目标更改为＆＃34; ES2017＆＃34;在tsconfig.json文件中。

这是我的tsconfig.json文件

{
"compilerOptions": {
/* Basic Options */
    "target": "ES2017",   /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017', or 'ESNEXT'. */
    "module": "commonjs", /* Specify module code generation: 'none', 'commonjs', 'amd', 'system', 'umd', 'es2015', or 'ESNext'. */
    "declaration": true,  /* Generates corresponding '.d.ts' file. */
    "sourceMap": true,    /* Generates corresponding '.map' file. */
    "outDir": "./dist",   /* Redirect output structure to the directory. */
    "strict": true        /* Enable all strict type-checking options. */
  },
  "include": [
    "src/**/*"

  "exclude": [

我遇到了同样的问题，这使我免于第二个问题：

在控制台中写这个：

urllib.request.urlopen(url)

在问题所在的文件中复制粘贴：

npm i --save bluebird
npm i --save-dev @types/bluebird @types/core-js@0.9.36

我遇到了相同的错误，并使用以下配置对其进行了修复：

文件：tsconfig.json 

  constructor(private route: ActivatedRoute) { }
  this.route.params.subscribe(params => {
    this.userdetails=params.token;
  });
}

答案 21 :(得分：0)

请注意，如果您运行的tsc命令的文件名为：

tsc testfile.ts

然后将忽略tsconfig.json编译器配置文件。 解决方案是单独运行tsc命令，否则将编译目录中的所有.ts文件，除非您已编辑tsconfig.json以包含一组文件。

请参阅“使用文件属性” ... https://www.typescriptlang.org/docs/handbook/tsconfig-json.html

答案 22 :(得分：0)

这里有同样的错误。我在tsconfig中使用“模块”：“ ES6”修复了该问题。
