从package.json安装依赖关系时出错

我刚刚下载了node.js，我试图从package.json安装一些依赖关系，并且我不断收到相同的错误。我尝试了最新版本和LTS，并且都给出了同样的错误。从package.json安装依赖关系时出错

package.json

{ 
    "name": "snake-ch3", 
    "dependencies": { 
     "express": "*", 
     "express-generator": "*" 
    }, 
    "devDependencies": { 
     "grunt": "~0.4.5", 
     "grunt-browserify": "~3.4.0", 
     "grunt-contrib-uglify": "~0.8.0", 
     "grunt-contrib-watch": "~0.6.1" 
    } 
}

和错误：

我验证了JSON上https://jsonformatter.curiousconcept.com/，寻找与 “Windows_NT 10.0.14393” JSON解析错误，我没有得到任何东西。

我重新安装了几次节点，所以它不是节点或下载问题。任何人都可以告诉我，如果我做错了什么？

EDIT

我只是tryied运行npm init与所有默认值，然后编辑它，所以它具有"dependencies"和"devDependencies"和它的作品突然。我尝试了再次按照之前的方式做这件事，而我也遇到了同样的错误。

现在看起来是这样的：

的package.json

{ 
    "name": "snake-game", 
    "version": "1.0.0", 
    "description": "a simple snake game", 
    "scripts": { 
    "test": "echo \"Error: no test specified\" && exit 1" 
    }, 
    "author": "Julian Avar", 
    "dependencies": { 
    "express": "*", 
    "express-generator": "*" 
    }, 
    "devDependencies": { 
     "grunt": "~0.4.5", 
     "grunt-browserify": "~3.4.0", 
     "grunt-contrib-uglify": "~0.8.0", 
     "grunt-contrib-watch": "~0.6.1" 
    } 
}

请确保'npm config获取注册表'返回'http：// registry.npmjs.org /'_without https_ –

您是从某处复制此文件还是自己创建它？如果你自己创造它，你是如何创造它的？ – Paul

如果没有，使用'npm config set registry http：// registry.npmjs.org /'来设置它，然后尝试安装你的软件包 –
