node.js - OpenAI API错误: "OpenAIApi is not a constructor"

Question

我想将 ChatGPT API(即 GPT-3.5 API)集成到我的应用程序中。我尝试了很多方法，但没有找到解决我的错误的方法。

我的代码:

require("dotenv").config();

const { Configuration, OpenAIApi } = require("openai");

const readline = require("readline");

const openaiapi = new OpenAIApi(
  new Configuration(
        new Configuration(
          { apiKey: process.env.OPENAI_API_KEY }
        )
    )
);

const userInterface = readline.createInterface({
  input: process.stdin,
  output: process.stdout,
});

userInterface.prompt();

userInterface.on("line", async (line) => {
  const response = await openaiapi.createChatCompletion({
    model: "gpt-3.5-turbo",
    messages: [{ role: "user", content: line }],
  });

  console.log(response);
});

错误:

Node.js v20.3.1

我尝试在互联网上搜索相关信息，但没有找到任何信息。

问题

如果您使用的是最新的 OpenAI NodeJS SDK 版本(即 v4)，则需要调整代码，因为 v4 与 不同v3 非常显着。您当前使用的代码适用于 v3，但不适用于 v4。请参阅下面的更改。

解决方案

初始化

改变这个...

// Old (i.e., OpenAI NodeJS SDK v3)
import { Configuration, OpenAIApi } from "openai";

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);

...对此。

// New (i.e., OpenAI NodeJS SDK v4)
import OpenAI from 'openai';

const openai = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
});

创建聊天完成

改变这个...

// Old (i.e., OpenAI NodeJS SDK v3)
const chatCompletion = await openai.createChatCompletion({
  model: "gpt-3.5-turbo",
  messages: [{role: "user", content: "Hello world"}],
});
console.log(chatCompletion.data.choices[0].message.content);

...对此。

// New (i.e., OpenAI NodeJS SDK v4)
const chatCompletion = await openai.chat.completions.create({
  model: "gpt-3.5-turbo",
  messages: [{"role": "user", "content": "Hello!"}],
});
console.log(chatCompletion.choices[0].message.content);

注意:SDK v4 为 released于2023年8月16日发布，并且是对SDK的完全重写。请参阅 v3 至 v4 migration guide .
