我直接从 OpenAI 的示例中复制了代码，结果却得到了一个初级的 Await JS 错误，但我不知道它期望我做什么。我只是想启动一个 Express.js 实例，并从 openapi（最终是 chatgpt）那里得到一个“hello world”的回应。Web 服务器本身运行正常。
这是我的代码：
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)错误信息如下：
SyntaxError: await is only valid in async functions and the top level bodies of modules at Object.compileFunction (node:vm:360:18) at wrapSafe (node:internal/modules/cjs/loader:1088:15) at Module._compile (node:internal/modules/cjs/loader:1123:27) at Module._extensions..js (node:internal/modules/cjs/loader:1213:10) at Module.load (node:internal/modules/cjs/loader:1037:32) at Module._load (node:internal/modules/cjs/loader:878:12) at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:81:12) at node:internal/main/run_main_module:23:47原始的 OpenAI 示例代码也是这样的。为什么这会是示例代码呢？
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);回答：
如前所述，您需要将异步代码包装在一个函数中：
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)另外，请确保您有一个包含适当依赖项的 package.json 文件：
{ "name": "sample", "version": "1.0.0", "description": "", "main": "index.js", "author": "", "license": "ISC", "dependencies": { "express": "^4.18.2", "openai": "^3.1.0" }}
