找不到模塊'pouchdb'，可在Mac上使用，但在Windows上無法使用

Question

我正在接管一個在我的隊友Mac上運行的離子項目。 使用ionic / cordova / python清潔Windows 10 PC。 該項目運行，但是發生以下錯誤。 我嘗試了多種不同的方式將pouchdb包含在項目中（使用@ types /使用較舊的版本，使用require而不是導入，刪除和重新安裝節點模塊等），但找不到此錯誤的任何方法。 我已還原所做的所有更改。 以下代碼適用於我的隊友mac。

我也只是和他核對過版本。 我正在運行所有相同版本的node / python / ionic等。

進口

//import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
import { Http, Headers, HttpModule } from '@angular/http';
import PouchDB from 'pouchdb';
import 'rxjs/add/operator/map';

Answer 1

您必須使用安裝PouchDB

npm install --save pouchdb

@types/pouchdb不是實際的模塊。 這只是打字稿的類型，您需要兩個模塊。
