“不支持的 OpenAPI / Swagger 版本 = 未定义”。无法对节点使用 express

我想用 express-openapi-validator 验证我的 api 请求，但每次我收到这个错误“Unsupported OpenAPI / Swagger version=undefined”。

不知道为什么会这样，只是为了我，我已经尝试过 github 上的其他人的代码也与他们的代码相同。

我卡住了。

我的 apiSpec.yaml 文件

我的 App.js

const bodyParser = require('body-parser');
const cors = require('cors');
const app = express();

// ** Setting Up Port
const port = 3000;

// ** Body Parser
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true, }));

// ** Adding Cors
app.use(cors());

// ** Open API Validator
new OpenApiValidator({
    "apiSpecPath": "./apiSpec.yaml"
}).install(app)

app.get("/", (req, res) => {
    res.send(`App Up & Running!`);
});

const contactList = [
    {
        id: '1',
        name: 'Johnny Depp',
        email: '[email protected]',
        mobile: '1234567'

app.get('/api/contact', (req, res) => {
    res.status(200).json(contactList);
});

app.post("/api/contact", (req, res) => {
    return res.json({ message: "Added successfully" });
});

app.get("/api/contact/:id", (req, res) => {

});

app.put("/api/contact/:id", (req, res) => {

});

app.delete("/api/contact/:id", (req, res) => {

});


app.listen(port, () => {
    console.log(`App listening at http://localhost:${port}`);
});

还尝试了多种其他方式，但仅以此错误结束
