【中文标题】成功解决后，带有打字稿的量角器找不到模块“量角器”【英文标题】：Protractor with typescript cannot find module 'protractor' after successfully resolved 【发布时间】：2017-04-09 13:32:09 【问题描述】：

这个问题要了我的命。请帮忙。我有以下文件结构：

node_modules
    protractor
    typescript
package.json
register-popup.ts

package.json的内容


    "name": "typescriptProba",
    "version": "1.0.0",
    "description": "",
    "main": "index.js",
    "scripts": 
        "test": "echo \"Error: no test specified\" && exit 1"
    ,
    "keywords": [],
    "author": "",
    "license": "ISC",
    "dependencies": 
         "protractor": "^4.0.11",
         "typescript": "^2.0.10"

import  ElementFinder, element, by  from "protractor";

export class RegisterPopup 
    public registerWithFacebookButton: ElementFinder = element(by.css('li.facebook a'));
    public registerWithGoogleButton: ElementFinder = element(by.css('li.google a'));
    public registerWithEmailButton: ElementFinder = element(by.css('li.email a'));
    public registerWithMobileButton: ElementFinder = element(by.css('li.natel a'));

    constructor () 

    openPopup() 
        element(by.css('.account.user')).click();
        element(by.id('openRegister')).click();
    

    openRegisterByEmailPopup() 
        this.registerWithEmailButton.click();
    

    openRegisterByPhonePopup() 
        this.registerWithMobileButton.click();

为了将 ts 文件编译为 js 文件，我使用以下命令：

./node_modules/typescript/bin/tsc "./register-popup.ts" --module commonjs --noResolve --traceResolution

执行命令后出现以下错误：

error TS2307: Cannot find module 'protractor'.

但是我的模块跟踪解析是这样的：

======== Resolving module 'protractor' from '/Users/predraglazarevic/www/typescriptProba/register-popup.ts'. ========
Module resolution kind is not specified, using 'NodeJs'.
Loading module 'protractor' from 'node_modules' folder.

'package.json' has 'typings' field 'built/index.d.ts' that references '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor/built/index.d.ts'.
File '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor/built/index.d.ts' exist - use it as a name resolution result.

======== Module name 'protractor' was successfully resolved to '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor/built/index.d.ts'. ========

所以我有

模块名称“量角器”已成功解析

但仍有错误

错误 TS2307：找不到模块“量角器”。

为什么？

回答

当我省略 --noResolve 标志时，它正在工作。所以命令应该是

./node_modules/typescript/bin/tsc "./register-popup.ts" --module commonjs

【问题讨论】：

你能分享你的tsconfig文件吗？没有tsconfig文件我不明白没有 tsconfig 文件你是如何编译的？我想你可以。其实我的ts文件是编译成js文件的，但是上面有错误当我省略 --noResolve 标志时，它正在工作。所以命令应该是 ./node_modules/typescript/bin/tsc "./register-popup.ts" --module commonjs 【参考方案1】：

首先你需要检查你的 tsconfig.json，你会看到 typeRoots


  "compileOnSave": false,
  "compilerOptions": 
    "declaration": false,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [
      "es2016"
    ],
    "module": "commonjs",
    "moduleResolution": "node",
    "outDir": "path/to/transpiled/files",
    "sourceMap": true,
    "target": "es6",
    "typeRoots": [
      "node_modules/@types"
    ]

如果您有任何其他的definitelyTyped 模块，它们将被本地路径中的typeRoots 目录拾取：node_modules/@types。

【讨论】：

更新上面的答案。 @types/protractor 已弃用。【参考方案2】：
