Firebase OpenAI API error: “openai.createCompletion is not a function“
题意 ：“Firebase OpenAI API 错误：‘openai.createCompletion is not a function’”
问题背景：
I am having an issue with running my Firebase function. It needs to generate a challenge once a day (I have it set up to run every minute now for debug) and to save it in my realtime database. This code is like this:
“我在运行 Firebase 函数时遇到了问题。它需要每天生成一次挑战（我现在将其设置为每分钟运行一次以进行调试），并将其保存到我的实时数据库中。代码如下：”
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const OpenAI = require("openai");
admin.initializeApp();
// Create a new instance of the OpenAI API client
const openai = new OpenAI({
apiKey: functions.config().openai.key,
});
exports.generateDailyChallenge = functions.pubsub.schedule("* * * * *")
.onRun(async (context) => {
try {
const response = await openai.createCompletion({
model: "text-davinci-003",
prompt: "You are an AI model powering a social media app based " +
"around challenges. The app works in a similar way to " +
"BeReal, meaning that once a day it generates a challenge " +
"for the users. The challenge needs to be simple to " +
"complete and require just a single photo taken from both " +
"cameras, just keep this in mind, but don't mention it as " +
"the users are used to it. The challenge is supposed to be " +
"fun, but easy to complete so users don't have to spend " +
"too much time on it. The goal is to connect with your " +
"online friends in a fun and engaging way. Mainly to just " +
"see what they were up to at that specific moment. Give me " +
"just the challenge name and a brief description of the " +
"challenge as if you were challenging a user to do it",
max_tokens: 150,
});
const challengeText = response.data.choices[0].text.trim();
console.log("Generated Challenge:", challengeText);
// Save to Firestore
const db = admin.firestore();
await db.collection("challenges").add({
text: challengeText,
createdAt: admin.firestore.FieldValue.serverTimestamp(),
});
} catch (error) {
console.error("Error generating or saving challenge:", error.message);
}
});
However when I run it I get this error in a log:
“但是，当我运行它时，我在日志中收到这个错误：”

}
When I tried debugging it I got told I don’t initialise the function properly. However that is not the case. And I also tried changing the way I initialise it so many time. I am using this to call it: https://www.npmjs.com/package/openai (it is the version 4.26.0), so I should initialise it this way.
“当我尝试调试时，有人告诉我我没有正确初始化该函数。然而事实并非如此。我也多次尝试更改初始化方式。我使用的是这个链接中的库来调用它：https://www.npmjs.com/package/openai（版本为 4.26.0），所以我应该这样初始化它。”
If nobody can help me maybe you can recommend me what other ai to use, because at this point I am suspecting it might be just an issue with OpenAI api.
“如果没有人能帮我，也许你可以推荐我使用其他的 AI，因为此时我怀疑这可能只是 OpenAI API 的问题。”
问题解决：
You have OpenAI Node.js SDK v4 or newer.
“你使用的是 OpenAI Node.js SDK v4 或更新版本。”
There are multiple changes in >=v4 compared to <v4, mainly:
“与 <v4 版本相比，>=v4 版本有多个变化，主要包括：”
- Initialization “初始化”
- Method names 方法名称
- Message retrieval “消息检索”
You did the initialization correctly. There are two problems left, plus one additional problem that is not related to the SDK version.
“你已经正确地进行了初始化。还有两个问题，另外还有一个与 SDK 版本无关的问题。”
Problem 1: Incorrect method name 问题1：错误的方法名称
You need to change the method name from this...
你需要将下面的方法名称
openai.createCompletion
...to this. 修改成以下名称
openai.completions.create
Problem 2: Incorrect message retrieval 问题2：错误的消息检索
Change this... 将以下语句
response.data.choices[0].text
...to this. 修改成下面的方式
response.choices[0].text
Additional problem: Using a deprecated model
“额外问题：使用了已弃用的模型”
Also, the text-davinci-003 has been deprecated. The gpt-3.5-turbo-instruct model is the recommended replacement.
“此外，text-davinci-003 已被弃用。建议使用 gpt-3.5-turbo-instruct 模型作为替代。”
