我正在使用Google Cloud vm实例运行我的节点应用程序,并且我已经安装了Ubuntu 16.04.6,已经安装了nodejs v11.10.1和npm v6.7.0,但是当我使用node app运行应用程序时,它显示为{ {1}}。我不知道这里出了什么问题。

这是我的package.json文件:

ReferenceError: post is not defined

这是我的发布路线:

{"name": "name",
 "version": "1.0.0",
 "description": "",
 "main": "app.js",
 "scripts": {
 "start": "node app.js",
 "deploy":"gcloud app deploy"
},
 "author": "Faiz Khan",
 "license": "ISC",
 "dependencies": {
 "bson": "^4.0.1",
 "connect-mongo": "^2.0.3",
 "ejs": "^2.6.1",
 "express": "^4.16.3",
 "express-session": "^1.15.6",
 "fabric": "^2.4.4",
 "jquery": "^3.3.1",
 "mongodb": "^2.2.33",
 "mysql": "^2.16.0",
 "node-fetch": "^2.3.0",
 "npm": "^6.4.1",
 "redis": "^2.8.0",
 "socket.io": "^2.0.3"
}
}

这是错误:

app.post('/chat',(req,res,next) =>{
userName = req.body.usrnm.toUpperCase();  
res.render('classLayout',{user:userName});
});

该应用程序可以在macOS上的localhost上运行良好,甚至在heroku上也可以,但是它只会在ubuntu上造成问题

您需要全局安装nodemon软件包才能在CLI中的任何目录中访问它。 为此,以下是您需要执行的命令。 :

npm install -g nodemon

对于您的“发布”错误,您需要共享app.js或路由文件中存在的代码段。

package.json没有nodemon具有dev依赖关系,并且尚未将其安装在计算机上。

  1. 运行npm install --save-dev nodemon,这会将“ devDependencies” 添加到package.json
  2. 在package.json中的“脚本” 中添加"preinstall": "npm i -g nodemon",

package.json

{
  "name": "name",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "scripts": {
    "preinstall": "npm i -g nodemon",
    "start": "node app.js",
    "deploy": "gcloud app deploy"
  },
  "author": "Faiz Khan",
  "license": "ISC",
  "dependencies": {
    "bson": "^4.0.1",
    "connect-mongo": "^2.0.3",
    "ejs": "^2.6.1",
    "express": "^4.16.3",
    "express-session": "^1.15.6",
    "fabric": "^2.4.4",
    "jquery": "^3.3.1",
    "mongodb": "^2.2.33",
    "mysql": "^2.16.0",
    "node-fetch": "^2.3.0",
    "npm": "^6.4.1",
    "redis": "^2.8.0",
    "socket.io": "^2.0.3"
  },
  "devDependencies": {
    "nodemon": "^1.18.10"
  }
} 

现在,当您部署到其他计算机或其他开发人员参与其中时,唯一需要执行的是npm install
