我已经制作了一个angularjs应用程序并在wamp服务器上运行它运行正常,但现在想在节点快递上移动它但在阅读之后我刚刚在package.json文件中进行了更改,如下所示:
{
"name": "Example",
"namelower": "example",
"version": "0.0.1",
"description": "An example AngularJS project",
"readme": "README.md",
"repository": {
"type": "git",
"url": "git@git.example.com:example.git"
},
"devDependencies": {
"grunt": "0.4.2",
"grunt-contrib-concat": "0.3.0",
"grunt-contrib-copy": "0.5.0",
"grunt-contrib-jshint": "0.8.0",
"grunt-contrib-nodeunit": "0.3.0",
"grunt-contrib-uglify": "0.2.2",
"grunt-contrib-watch": "0.5.3",
"grunt-exec": "0.4.5",
"grunt-jsdoc": "0.5.4",
"grunt-karma": "0.8.3",
"karma": "0.12.16",
"karma-jasmine": "0.1.5",
"karma-ng-html2js-preprocessor": "^0.1.2",
"karma-phantomjs-launcher": "0.1.4"
},
"scripts": {
"postinstall": "bower install",
"test": "grunt build"
},
"dependencies": {
"protractor": "^2.1.0"
"express" : "~4.7.2",
"mongoose" : "~3.6.2",
"morgan" : "~1.2.2",
"body-parser": "~1.5.2",
"method-override": "~2.1.2"
}
}
编辑package.json后,我在cmd上运行了npm install但是得到了这个
error:C:\wamp\www\First-angular-App>npm install
npm ERR! install Couldn't read dependencies

我怎么能这样做以及我需要在node express上运行我的应用程序需要做些什么?

你在第33行的"protractor": "^2.1.0"
后遗漏了一个逗号。
如果您不能手动编写package.json,请使用npm init
,然后使用--save
从控制台安装所有软件包。这样你就可以避免拼写错误。

首先在应用程序路径中打开cmd
,然后键入npm init
。提供必要的信息。
使用npm i express
安装express并创建server.js
文件,如下所示:
const express = require('express') const app = express(); const port = 3000; var path = require("path"); app.get('/',function(req,res){ res.sendFile(path.join(__dirname+'/index.html')); }); app.listen(port, () => console.log(`Example app listening on port ${port}!`))
打开http://localhost:3000/以查看输出。它将呈现index.html
。
