node.js - 为什么将 "yo polymer"与 yeoman 一起使用不会使用 webcomponent 文件夹创建 Bower 文件夹？

Question

我遇到了这个问题，我正在尝试使用 Yeoman 创建我的聚合物项目。问题是当命令成功完成时，但当我转到文件夹时，我发现项目中未创建文件夹 bower_components 。

我检查了一下，一切都已安装，“npm”、“bower”、“yeoman”和“聚合物生成器”

Yeoman Doctor Running sanity checks on your system

✔ Global configuration file is valid ✔ NODE_PATH matches the npm root ✔ Node.js version ✔ No .bowerrc file in home directory ✔ No .yo-rc.json file in home directory ✔ npm version

Everything looks all right!

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"
  },
  "devDependencies": {},
  "ignore": []
}

这些是项目文件夹内的文件夹和文件:

• CONTRIBUTING.md

• README.md

• bower.json

• Node 模块

• 任务

• LICENSE.md

• 应用程序

• gulpfile.js

• package.json

• travis-runner.sh

如果您看到我正在运行命令yo doctor并且一切看起来都正常。

在项目文件夹中创建的文件和文件夹:

create bower.json
   create package.json
   create app/cache-config.json
   create app/elements/elements.html
   create app/elements/my-greeting/my-greeting.html
   create app/elements/my-list/my-list.html

   create gulpfile.js
   create wct.conf.js
   create app/test/index.html
   create app/test/my-greeting-basic.html
   create app/test/my-list-basic.html

请帮忙吗？

您需要在项目根目录中运行 bower install 才能获取 bower_components 目录。通常，Yeoman 生成器在设置后会为您运行此命令，但看起来您必须自己手动运行它。

这会将 bower.json 中列出的所有依赖项安装到目录 bower_components 中。
