OpenAI API 错误：“TypeError：OpenAIApi 不是构造函数”

Question

我在尝试获取此代码来调用

.env

文件中的 OPENAI_API_KEY 时遇到问题。我对 Node.js 很陌生，所以请像我是个白痴一样跟我说话。

请参阅代码后面底部的错误。

代码：

require('dotenv').config();
const { OpenAIApi } = require('openai');

// Initialize OpenAI API client with the API key from your .env file
const openaiClient = new OpenAIApi(process.env.OPENAI_API_KEY);


/**
 * Generates a response using ChatGPT-4 Turbo based on the provided user input.
 * @param {string} userInput - The user's message input.
 * @returns {Promise<string>} - The generated response from ChatGPT-4 Turbo.
 */
async function generateResponse(userInput) {
  try {
    console.log('Sending input to OpenAI API:', userInput);
    const response = await openaiClient.createChatCompletion({
      model: "gpt-4-turbo",
      messages: [{
        role: "user",
        content: userInput
      }],
    });

    if (response.data.choices && response.data.choices.length > 0) {
      console.log('Received response from OpenAI API');
      return response.data.choices[0].message.content;
    } else {
      console.log('No response from OpenAI API.');
      throw new Error('No response from OpenAI API');
    }
  } catch (error) {
    console.error('Failed to generate response from OpenAI API:', error.message, error.stack);
    throw error; // Rethrow to handle it in the calling function
  }
}

module.exports = { generateResponse };

错误：

const openaiClient = new OpenAIApi(process.env.OPENAI_API_KEY);
                     ^

Node.js v20.11.1

我也尝试过这个，但它不起作用：

const { OpenAIApi } = require('openai');

Answer 1

第 1 步：安装最新的 OpenAI Node.js SDK

您在上面的评论中说您想使用最新的语法。因此，首先，请确保您安装了最新的 OpenAI Node.js SDK。运行以下命令：

npm install openai@latest

截至今天，

v4.29.0

是最新的。在继续之前，请通过运行以下命令检查版本：

npm view openai version

您应该在终端中看到

4.29.0

。

第 2 步：修复代码

您的代码中有多个错误，但您还不知道它们，因为初始化是引发的第一个错误。修复这个错误后，才会抛出下一个错误。

OpenAI Node.js SDK >=

v4

（即，包括最新的）与 <

v4

相比有很多重大变化。其中，也是初始化导致了你的错误。但正如我所说，你的代码中有更多错误。

以下是使用 OpenAI Node.js SDK 的正确初始化 >=

v4

:

const OpenAI = require("openai");

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

以下是使用 OpenAI Node.js SDK 的正确方法名称 >=

v4

:

openai.chat.completions.create

以下是使用 OpenAI Node.js SDK 的正确消息检索 >=

v4

:

response.choices[0].message.content

完整代码

require('dotenv').config();
const OpenAI = require("openai");

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

async function generateResponse(userInput) {
  try {
    console.log('Sending input to OpenAI API:', userInput);
    const response = await openai.chat.completions.create({ // Method name
      model: "gpt-4-turbo",
      messages: [{
        role: "user",
        content: userInput
      }],
    });

    if (response.choices && response.choices.length > 0) {
      console.log('Received response from OpenAI API');
      return response.choices[0].message.content; // Message retrieval
    } else {
      console.log('No response from OpenAI API.');
      throw new Error('No response from OpenAI API');
    }
  } catch (error) {
    console.error('Failed to generate response from OpenAI API:', error.message, error.stack);
    throw error;
  }
}

module.exports = { generateResponse };
