我尝试在Google App Engine上部署我的Nest.js，但无法成功部署...
复现：
nest new my-project
在
src/main.ts 中。import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
async function bootstrap() {
const app = await NestFactory.create(AppModule);
await app.listen(process.env.PORT || 8080);
}
bootstrap();

部署
gcloud app deploy
过了一会儿，GAE日志显示 Nest 应用程序成功启动，但GAE立即关闭并显示以下消息：

在stderr上没有错误日志。
然而，我可以成功地部署一个简单的HTTP服务器，如下所示：
app.js
const http = require('http');
const server = http.createServer((req, res) => {
res.end(`Hello World\n`);
});
server.listen(process.env.PORT || 8080, () => {
console.log('app started');
});
app.yaml
runtime: nodejs12
package.json
{
"name": "appengine",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "node app.js",
"test": "echo \"Error: no test specified\" && exit 1"
},
"keywords": [],
"author": "",
"license": "ISC"
}
成功运行 gcloud app deploy 并且没有出现任何问题。
非常感谢任何帮助。
解决方案
将 "gcp-build": "npm run build" 添加到 package.json 中。
然后就可以正常运行而没有任何问题了。
