npm run build给出npm ERR！代码ELIFECYCLE

我对Node.js和Electron非常陌生，想运行npm run build。不幸的是，这只给了我错误代码ELIFECYCLE。

这是我的package.json：

{
    "name": "firstelectronproject",
    "version": "0.1.0",
    "description": "My first Electron project",
    "main": "main.js",
    "scripts": {
        "start": "electron index.js",
        "package": "",
        "build": "electron-packager . FEP"
    },
    "author": "F9lke <florian.thomasgoetzrath.de>",
    "license": "MIT",
    "dependencies": {
        "electron": "^1.6.11"
    },
    "devDependencies": {
        "asar": "^0.13.0",
        "electron-packager": "^8.7.2"
    }
}

这是我的命令提示符的日志：
