无法在我的项目中导入PouchDB

无法在我的项目中导入PouchDB

问题描述:

我正在开发一个项目,最近PouchDB决定停止工作。我不能在我的ts项目中编译它。我想:无法在我的项目中导入PouchDB

import * as PouchDB from 'pouchdb'; 

export default PouchDB.defaults({ 
    prefix: `http://admin:[email protected]:5984/` 
}) 

,但我得到

server/src/database.ts(3,24): error TS2339: Property 'defaults' does not exist on type 'typeof 'pouchdb''. 

如果我尝试:

import {PouchDB} from 'pouchdb'; 

export default PouchDB.defaults({ 
    prefix: `http://admin:[email protected]:5984/` 
} as any) 

我得到

server/src/database.ts(1,9): error TS2305: Module ''pouchdb'' has no exported member 'PouchDB'. 

如果我尝试:

import PouchDB from 'pouchdb'; 

export default PouchDB.defaults({ 
    prefix: `http://admin:[email protected]:5984/` 
} as any) 

然后,它会编译,但我得到这个当我运行它:

export default PouchDB.defaults({ 
        ^
TypeError: Cannot read property 'defaults' of undefined 
    at Object.<anonymous> ... 

如果我尝试:

const PouchDB = require('pouchdb'); 

我失去了所有的类型,所以就变成了any型我OBV不想要

❯ npm ls pouchdb @types/pouchdb 
[email protected] /mnt/c/Users/Vincent/Documents/GitHub/compactd 
├── @types/[email protected] 
└── [email protected] 

我停止工作之前做的唯一事情是清理node_modules并重新启动所有使用npm而不是纱线(纱线希望重新编译所有我的本地模块,每次我安装的东西,但我觉得npm是这样做的)

我试着降级PouchDB到6.2.0,我疯狂的任何帮助将非常感激。

使用TS-节点,我试图要求/进口PouchDB一切可能的方式:

> require('pouchdb') 
{ [Function: PouchDB$5] 
    super_: 
    { [Function: AbstractPouchDB] 
    super_: 
     { [Function: EventEmitter] 
     EventEmitter: [Object], 
     usingDomains: true, 
     defaultMaxListeners: [Getter/Setter], 
     init: [Function], 
     listenerCount: [Function] } }, 
    adapters:... 

> import PouchDB from 'pouchdb' 
undefined 
> PouchDB 
undefined 

> import * as PouchDB from 'pouchdb' 
[eval].ts:2 
Object.defineProperty(exports, "__esModule", { value: true }); 
        ^

我的猜测是你的node_modules文件夹中有一个PouchDB的旧版本,并且它的界面已更改。也许尝试在'node'或'ts-node' REPL中导入(或要求)该模块?然后,您可以记录您的PouchDB对象,并查看其上可用的属性。如果你的类型定义不匹配,这不会解决问题,但也许它可以帮助找到排队的PouchDB和@ types/PouchDB版本 –

@NathanWilson调试了很多之后,我发现我想要的定义在自6.0.5以来的'pouchdb/lib/index.es'中。当然,我不能直接导入.es文件,没有发现类型。试图安装6.0.4现在... – Vinz243

Nvm,仍然无法使用6.0.4 ... – Vinz243

截至目前,最好的解决方法是:

import Pouch from 'pouchdb'; 
const PouchDB: typeof Pouch = require('pouchdb'); 

这是快速和肮脏的,但真正的修复需要由pouchDB维护人员完成
