导读：这个问题让我很难过.请帮忙. 我有以下文件结构： node_modules protractor typescriptpackage.jsonregister-popup.ts package.json的内容 { "name": "typescriptProba","version": "1.0.0","description": "","main": "index.js","scripts": { "test": "echo

这个问题让我很难过.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,我有以下错误：

error TS2307: Cannot find module 'protractor'.

但我的模块跟踪分辨率是这样的：

======== 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.
File '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor.ts' does not exist.
File '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor.tsx' does not exist.
File '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor.d.ts' does not exist.
Found 'package.json' at '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor/package.json'.
'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.
Resolving real path for '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor/built/index.d.ts',result '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor/built/index.d.ts'
======== Module name 'protractor' was successfully resolved to '/Users/predraglazarevic/www/typescriptProba/node_modules/protractor/built/index.d.ts'. ========

所以我有

Module name ‘protractor’ was successfully resolved

但仍然有错误

error TS2307: Cannot find module ‘protractor’.

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

解决方法

首先,您需要检查tsconfig.json,您会看到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DefinitelyTyped模块,它们将被本地路径中的typeRoots目录选取：node_modules / @ types.
