javascript - Node 找不到模块

我是node和javascript的新手，我正在尝试利用以下库:https://github.com/Applifting/stv
我无法弄清楚为什么我总是得到以下“错误:找不到模块'./stv'”
我已经阅读了几个类似的问题和答案，但是没有建议的解决方案，例如重新安装node和npm，都没有帮助。
下面是我用来设置package.json和安装stv模块的设置。

C:\votecount>npm init -y
Wrote to C:\votecount\package.json:

{
  "name": "votecount",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC"
}

C:\votecount>npm add stv
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN [email protected] No description
npm WARN [email protected] No repository field.

+ [email protected]

package.json正确显示了依赖项下的stv。

  "name": "votecount",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "stv": "0.0.2"
  },

然后，我创建了一个index.js文件，其中包含:const stv = require('stv')然后，当运行index.js时，我得到以下信息。

C:\votecount>node index.js
internal/modules/cjs/loader.js:968
  throw err;
  ^

  ]
}

C:\votecount>node -v
v12.18.4

C:\votecount>npm -v
6.14.6

但是，当我尝试安装Express模块​​的此过程时，我没有任何问题，可以成功导入该模块。

const express = require('express')
const app = express();

正如表达似乎很好，我不确定如何进一步解决此问题。我可以看到我正在尝试使用的stv模块的一部分已经用typescript编写，但是特定的stv package.json似乎可以解决这个问题。
任何帮助解决此错误的问题将不胜感激。
编辑:
我也尝试按照git的说明使用import { stv } from 'stv';，但出现另一个错误:

C:\votecount>node index.js
(node:5432) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
C:\votecount\index.js:1
import { stv } from 'stv';
^^^^^^

SyntaxError: Cannot use import statement outside a module

如果然后在根目录中的package.json中添加“type”:“module”，则得到:

C:\votecount>node index.js
(node:15736) ExperimentalWarning: The ESM module loader is experimental.
file:///C:/votecount/index.js:1
import { stv } from 'stv';
         ^^^
SyntaxError: The requested module 'stv' is expected to be of type CommonJS, which does not support named exports. CommonJS modules can be imported by importing the default export.
For example:
import pkg from 'stv';
const { stv } = pkg;

将index.js更新为import pkg from 'stv'; const { stv } = pkg;，然后返回原始的“错误:找不到模块'./stv'”

最佳答案

该软件包未正确发布。只有一个编译文件dist/index.js。应该有更多的文件。

examples  index.d.ts  index.js  model.d.ts  model.js  stv.d.ts  stv.js  stv.spec.d.ts  stv.spec.js  utils.d.ts  utils.js

一种解决方案是-

fork 仓库

将其克隆到您的项目中

cd变成stv

安装模块

运行tsc

然后

const stv = require('./stv/dist')
