bower-installer中的bug，找不到bower.json

Question

厌倦了凉亭下载我安装的每个仓库中的所有内容，我设置了bower-installer。

然而，在运行bower-installer后，我收到了这个奇怪的错误：

bower-installer
/usr/local/lib/node_modules/bower-installer/bower-installer.js:56
    throw createError('Neither bower.json nor component.json present', 'ENOEN

我的bower.json文件就在那里，下面是什么：

{
  "name": "app",
  "main": "app.js",
  "version": "0.0.0",
  "authors": [
    "Leon"
  ],
  "description": "My app",
  "keywords": [
    "tags",
    "manage"
  ],
  "license": "MIT",
  "homepage": "me.com",
  "private": true,
  "ignore": [
    "**/.*",
    "node_modules",
    "bower_components",
    "test",
    "tests"
  ],
  "dependencies": {
    "angular-bootstrap": "~0.12.1",
    "angular-loader": "1.2.x",
    "angular-mocks": "~1.2.x",

    "angular-scroll": "~0.6.5",
    "chartist": "~0.7.3",
    "bootstrap": "~3.3.4",
    "angular": "~1.3.15"
  },
  "install": {
    "path": "libs",
    "sources": {
      "angular": "bower_components/angular/angular.min.js",
      "bootstrap": "bower_components/bootstrap/dist/js/bootstrap.min.js",
      "chartist": [
        "bower_components/chartist/dist/chartist.min.js",
        "bower_components/chartist/dist/chartist.min.css",
      ],
      "angular-scroll": "bower_components/angular-scroll/angular-scroll.min.js",
      "angular-route": "bower_components/angular-route/angular-route.min.js",
      "angular-mocks": "bower_components/angular-mocks/angular-mocks.js",
      "angular-loader": "bower_components/angular-loader/angular-loader.min.js",
      "angular-bootstrap": [
        "bower_components/angular-bootstrap/ui-bootstrap-tpls.js",
        "bower_components/angular-bootstrap/ui-bootstrap-tpls.min.js",
        "bower_components/angular-bootstrap/ui-bootstrap.js",
        "bower_components/angular-bootstrap/ui-bootstrap.min.js"
      ]
    }
  }
}

您的bower.json不正确，此部分

"chartist": [
  "bower_components/chartist/dist/chartist.min.js",
  "bower_components/chartist/dist/chartist.min.css",
],

应该是

"chartist": [
  "bower_components/chartist/dist/chartist.min.js",
  "bower_components/chartist/dist/chartist.min.css"
],

所以删掉最后一个逗号。该逗号使json无效，因此bower安装程序无法解析它。我用你的bower.json验证了这一点，删除逗号后它工作正常。
