NodeJS + Typescript + Docker 运行时报错

编程问答 2022-05-01

问题描述

我正在尝试在 NodeJS + Typescript 中对接和 Api，但显然当我配置为使用 docker 运行它时，发生了一些奇怪的事情。

如果我尝试使用 ts-node 提供它，例如： NODE_ENV=development ts-node ./dist/src/index.js 工作正常，但我尝试使用 pm2 它抱怨：

SyntaxError: Cannot use import statement outside a module

以下是我的配置：

ecosystem.config.json

{
  "apps": [
    {
      "name": "server","script": "./dist/src/index.js","instances": "max","autorestart": false,"watch": "./dist/**/*.js","env": {
        "NODE_ENV": "development"
      },"env_production": {
        "NODE_ENV": "production"
      }
    },{
      "name": "server-watcher","script": "yarn start","instances": 1,"watch": "tsconfig.json","env_production": {
        "NODE_ENV": "production"
      }
    }
  ]
}
