找不到模块'pouchdb'，适用于mac，但不适用于windows

Question

我正在接管一个适用于我的 mates mac 的 ionic 项目。清洁安装了 ionic/cordova/python 的 windows 10 PC。项目运行，但出现以下错误。我尝试了多种在项目中包含 pouchdb 的不同方法（使用 @types/ 使用旧版本，使用 require 而不是导入、删除和重新安装节点模块等），但我找不到任何解决此错误的方法。我已经恢复了我所做的所有更改。以下代码适用于我的 mates mac。

我也刚刚与他核实了版本。我正在运行所有相同版本的 node/python/ionic 等。

导入

//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

你必须安装 PouchDB

npm install --save pouchdb

@types/pouchdb 不是实际的模块。这只是打字稿的打字。你需要两个模块。
