Cannot find module '@ioc:Adonis/Core/Env'

[AlirezaEthDev]

I compiled server.ts to server.jsfile but the below error throwed:

server.ts:

import 'reflect-metadata'
import sourceMapSupport from 'source-map-support'
import { Ignitor } from '@adonisjs/core/build/standalone'

sourceMapSupport.install({ handleUncaughtExceptions: false })

new Ignitor(__dirname)
  .httpServer()
  .start()

server.js:

"use strict";
var __importDefault = (this && this.__importDefault) || function (mod) {
    return (mod && mod.__esModule) ? mod : { "default": mod };
};
Object.defineProperty(exports, "__esModule", { value: true });
require("reflect-metadata");
const source_map_support_1 = __importDefault(require("source-map-support"));
const standalone_1 = require("@adonisjs/core/build/standalone");
source_map_support_1.default.install({ handleUncaughtExceptions: false });
new standalone_1.Ignitor(__dirname)
    .httpServer()
    .start();
//# sourceMappingURL=server.js.map

Error:

Hey @AlirezaEthDev! 👋🏻

Please provide your package.json and a repository with the minimum amount of code required to reproduce your error.

[AlirezaEthDev]

Thanks a lot.
According to the document, I tried node ace serve --watch but these exception and warnings throwed:

[ info ]  building project...
[ info ]  starting http server...

   Exception: E_MISSING_ENV_VALUE: Missing environment variable "APP_KEY"

And this is env.ts:

import Env from '@ioc:Adonis/Core/Env'

export default Env.rules({
	HOST: Env.schema.string({ format: 'host' }),
	PORT: Env.schema.number(),
	APP_KEY: Env.schema.string(),
	APP_NAME: Env.schema.string(),
  	DRIVE_DISK: Env.schema.enum(['local'] as const),
	NODE_ENV: Env.schema.enum(['development', 'production', 'test'] as const),
})

And this is server.ts:

/*

import 'reflect-metadata'
import sourceMapSupport from 'source-map-support'
import { Ignitor } from '@adonisjs/core/build/standalone'

sourceMapSupport.install({ handleUncaughtExceptions: false })

new Ignitor(__dirname)
  .httpServer()
  .start()

So what do you understand from this error: Exception: E_MISSING_ENV_VALUE: Missing environment variable "APP_KEY"?

[AlirezaEthDev]

Do you mean I should generate an app key and import it to the application? If yes. I tried node ace generate:key but I don't know how to add it to the application.

I'm unfamiliar with the AdonisJS and this the first time I work with it.

[RomainLanz]

It means you are missing your environment variables.

Then why not learning the framework by following our course?

[AlirezaEthDev]

Yes, I read the document, add this .env and the issue solved for development:

PORT=3333
HOST=0.0.0.0
NODE_ENV=development
APP_KEY=sH2k88gojcp3PdAJiGDxof54kjtTXa3g
SESSION_DRIVER=cookie
