bower.json文件时，bower install --save GoogleWebComponents/google-map
收到错误消息后，它会被击中或错过：
ECONFLICT Unable to find suitable version for polymer
以下是完整输出：

这是我的bower.json文件：
{
"name": "polymer-starter-kit",
"private": true,
"dependencies": {
"iron-elements": "PolymerElements/iron-elements#^1.0.0",
"neon-elements": "PolymerElements/neon-elements#^1.0.0",
"page": "visionmedia/page.js#~1.6.4",
"paper-elements": "PolymerElements/paper-elements#^1.0.1",
"platinum-elements": "PolymerElements/platinum-elements#^1.1.0",
"polymer": "Polymer/polymer#^1.2.0",
"iron-swipeable-pages": "^1.2.3",
"parallax-container": "^1.1.1",
"juicy-html": "^1.1.0",
"html-include": "^0.1.2",
"scroll-progress": "^0.0.3",
"tem-waypoint": "^1.0.0"
},
"devDependencies": {
"web-component-tester": "^4.0.0"
},
"ignore": []
}
我可以做些什么来缓解这个问题吗？我不得不手动将n drop依赖项拖放到项目中，除此之外，他们没有保存到我的bower文件中（打败了bower的目的）。
任何帮助将不胜感激！
