如何在 Google App Engine 中发布 Nestjs api？

Question

我正在尝试将我的 nestjs api 放入 Google App Engine，但我仍然有错误。 我首先使用谷歌 sdk 创建了我的谷歌云项目，编辑我的代码如下：

main.ts：

import {NestFactory} from '@nestjs/core';
import {DocumentBuilder, SwaggerModule} from '@nestjs/swagger';
import {AppModule} from './app.module';
import {ValidationPipe} from "@nestjs/common";
import * as cookieParser from 'cookie-parser';
import * as helmet from 'helmet';
import * as Express from 'express';
import { ExpressAdapter } from '@nestjs/platform-express';


const server = Express();
server.get('/',(req,res) => res.send('ok'));
server.get('/_ah/health',(req,res) => res.send('ok'));

async function bootstrap() {
    const app = await NestFactory.create(AppModule, new ExpressAdapter(server), { cors: true });

    //Validation
    app.useGlobalPipes(new ValidationPipe({
        whitelist: true,
    }));

    //Swagger
    const config = new DocumentBuilder()
        .setTitle('Title')
        .setDescription('Description')
        .addBearerAuth()
        .setVersion('2.0')
        .build();
    const document = SwaggerModule.createDocument(app, config);
    SwaggerModule.setup('doc', app, document);

    //Use Cookies
    app.use(cookieParser());

    //Security
    //1 - Helmet
    app.use(helmet());
    //2 - CORS :/
    app.enableCors();


    await app.listen(8080);
}

bootstrap();

当我尝试部署项目时，我收到此错误：

sh: 1: nest: not found
operable program or batch file.
npm ERR! code ELIFECYCLE

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我已经完成了“npm install”，但脚本似乎无法识别命令嵌套。 关于发生了什么的任何想法？ 提前致谢

看看另一个帖子：

找不到嵌套命令

看来您需要安装和使用 npm 为：

@nestjs/cli而不仅仅是nest
