OpenAI API in node gives basic Await error. How do I fix?

题意：OpenAI API 在 Node 中出现基本的 Await 错误。我该如何修复？

问题背景：

I literally copied the code from the openAI example and it gives me a remedial Await JS error but I am unsure what it expects me to do. I just want to spin up an Express.js instance and get a hello world from openapi (eventually chatgpt). The web server works fine.

我照搬了 OpenAI 示例中的代码，但出现了基本的 Await JS 错误，我不确定它希望我怎么做。我只是想启动一个 Express.js 实例，并从 OpenAI（最终是 ChatGPT）获取一个 Hello World。网络服务器运行正常

Here is my code: 以下是我的代码

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


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

const configuration = new Configuration({
  apiKey: "my key is here"
});
const openai = new OpenAIApi(configuration);

const completion = await openai.createCompletion({
  model: "text-davinci-002",
  prompt: "Hello world",
});
console.log(completion.data.choices[0].text);



app.get('/', function (req, res) {
  res.send('Hello World')
})

app.listen(3000)

Error: 以下是错误信息

SyntaxError: await is only valid in async functions and the top level bodies of modules

The original OpenAI example code is the same. Why the hell is this the example code?

原始的 OpenAI 示例代码是一样的。这为什么还是示例代码

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

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

const completion = await openai.createCompletion({
  model: "text-davinci-002",
  prompt: "Hello world",
});
console.log(completion.data.choices[0].text);

问题解决：

As already mentioned, you need to wrap your async code in a function:

如前所述，你需要将异步代码封装在一个函数中

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

const configuration = new Configuration({
  apiKey: "my key is here"
});

const openai = new OpenAIApi(configuration);

const completionFunction = async () => {
  const completion = await openai.createCompletion({
    model: "text-davinci-002",
    prompt: "Hello world",
  });
  
  console.log(completion.data.choices[0].text);
};

completionFunction();

app.get('/', function (req, res) {
  res.send('Hello World')
})

app.listen(3000)

Also, make sure you have a package.json file with the appropriate dependencies:

此外，请确保你有一个包含适当依赖项的 package.json 文件
