“STAGE”未被识别为内部或外部命令

Question

这是一个使用 Nestjs 和 Mongoose 的后端服务器。但如果我进入-

> npm run start:dev

它显示--- “STAGE”未被识别为内部或外部命令

我认为 .env 有问题。如果有人可以的话请回答。

代码

.env.stage.dev

MONGO_DATABASE=dbName
MONGO_USERNAME=myName
MONGO_PASSWORD=myPass
MONGO_HOST=localhost:27017
MONGO_CONNECTION_STRING=mongodb://localhost:27017

import { Module } from '@nestjs/common';
import { AppController } from './app.controller';
import { AppService } from './app.service';
import { MongooseModule } from '@nestjs/mongoose';
import { TitleModule } from './titles/title.module';
import { TopicsModule } from './topics/topics.module';
import { AssetsModule } from './assets/assets.module';
import { ConfigModule, ConfigService } from '@nestjs/config';

@Module({
  imports: [
    MongooseModule.forRootAsync({
      imports: [ConfigModule],
      useFactory: async (configService: ConfigService) => {
        const username = configService.get('MONGO_USERNAME');
        const password = configService.get('MONGO_PASSWORD');
        const database = configService.get('MONGO_DATABASE');
        const host = configService.get('MONGO_HOST');
        const devConnectionString = configService.get(
          'MONGO_CONNECTION_STRING',
        );
        return {
          uri: `mongodb://${username}:${password}@${host}`,
          dbName: database,
        };
      },
      inject: [ConfigService],
    }),
    TitleModule,
    TopicsModule,
    AssetsModule,
    ConfigModule.forRoot({
      isGlobal: true,
      envFilePath: [`.env.stage.${process.env.STAGE}`],

在package.json中

SET STAGE=dev nest start --watch

或

cross-env STAGE=dev nest start --watch
