import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
async function bootstrap() {
const serverConfig = config.get('server')
const app = await NestFactory.create(AppModule);
app.enableCors();
const port = process.env.Port|| 3000
await app.listen(port);
}
bootstrap();
有没有办法解决这个问题?
我尝试添加一些脚本,如
“heroku后期生成”:“echo Skip在heroku上生成”
但也没用
编辑
问题已经解决了,因为我在config.yml文件中使用了一个变量,heroku出于某种原因一直拒绝它 您在
package.json中对postinstall脚本的配置不正确
"postinstall": "npm run prestart:prod",
"prestart:prod": "npm install",
它所做的是再次触发npm安装
。
在heroku上,运行install会在安装完成后触发postinstall,包括通过命令手动运行npm install
所以您运行install,它触发postinstall,它触发另一个安装,等等
我不知道你想用这个脚本完成什么,但因为它实际上没有任何作用,我建议你干脆从package.json中删除它。我删除了它,但仍然无法工作,我得到了at=error code=H10 desc=“App crash”method=get path=“/”host=api-prod-nest.herokapp.com request\u id=40cefc3c1-bf44-4cf5-b424-29f2108ecaf4-fwd="77.31.44.244“dyno=connect=service=status=503字节=protocol=https
,我是这样说的:但一切都不起作用。这似乎是一个与你提出的问题无关的问题,可能应该分开讨论question@Ruqayya我认为在main.ts
中,您应该使用PORT
而不是PORT
作为@NatanDeitch,这实际上是另一个错误,谢谢
