Angular 4，ng2-redux:找不到模块“redux-logger"的声明文件 [英] Angular 4, ng2-redux: Could not find a declaration file for module 'redux-logger'

问题描述

我从 git clone https://github.com/angular/quickstart.git

和

npm i --save redux-logger redux ng2-redux

这里.../node_modules/redux-logger/src/index.js有

export { defaults, createLogger, defaultLogger as logger };

错误:TS7016:找不到模块redux-logger"的声明文件.'.../node_modules/redux-logger/dist/redux-logger.js' 隐式具有 'any' 类型.

import { applyMiddleware, createStore } from 'redux';
import logger from 'redux-logger';
//import { createLogger } from 'redux-logger';

const store = createStore(
  rootReducer,
  applyMiddleware(logger)
);

//const store = createStore(
//  rootReducer,
//  applyMiddleware(createLogger())
//);

使用 createLogger() 时同样的错误

The same error when using createLogger()

如何解决这个问题?

谢谢.

推荐答案

您必须使用 typescript.为了导入任何 javascript 库/模块，您需要其相应的类型声明，这些声明通常包含在 绝对输入.

You must be using typescript. In order to import any javascript library/module, you need its corresponding type declarations which are generally included in DefinitelyTyped.

做:

npm i @types/redux-logger --save-dev

包在这里.然后你可以导入为:

The package is here. Then you can import as:

import { createLogger } from 'redux-logger';
