无法使用生态系统.config.js在pm2中设置环境React app webpack app

Question

我的package.json文件如下所示，用于在pm2中运行的hgweb应用 package.json

    "typescript": "^3.0.3"
  }
}

无法为使用以上package.json文件的react应用设置环境。我的pm2生态系统.config.json文件如下所示

module.exports = {
  apps : [
    {
     name      : "HGBackend",
     cwd       : "hgbackend/server",
     script    : "server.js",
     env       :
         {
            "PORT": 3000,
            "NODE_ENV": "staging"
        }
    },
    {
    name       : "HGBlockchain",
    cwd        : "hgblockchain/localgrammes",
    script     : "index.js"
   // args       : "start:staging"
   // instances  : 4,
   // exec_mode  : "cluster"
  },
  {
    name   : "HGWeb",
    cwd    : "hgweb/src/server",
    script : "server.js",
    env : {
        NODE_ENV: 'staging'
      },
    description: ""
  }

我无法在pm2中设置React应用环境。它适用于后端和区块链应用程序。任何人都可以建议我在pm2中使用webpack运行react app
