Bower is deprecating their registry hosted with Heroku. http://bower.herokuapp.com/Will not be accessible anymore or it might be down intermittently, therefore, forcing users to a new registry.
Bower 正在弃用由 Heroku 托管的注册表。http://bower.herokuapp.com/将无法再访问，或者它可能会间歇性地关闭，因此，迫使用户使用新的注册表。
Users working on old bower versions can update the .bowerrcfile with the following data.
使用旧 bower 版本的用户可以使用以下数据更新.bowerrc文件。
{
"registry": "https://registry.bower.io"
}
.bowerrcfile can be located at the same folder where bower.jsonand bower_componentsfolder is located. If it is not present already, you can make one.
.bowerrc文件可以位于bower.json和bower_components文件夹所在的同一文件夹中。如果它不存在，您可以制作一个。

If you use windows to install npm, You must run "Node.js command prompt" with administrator and run this command: npm i -g bower. I tried and worked :)
如果您使用 Windows 安装 npm，您必须以管理员身份运行“Node.js 命令提示符”并运行此命令：npm i -g bower。我尝试过并工作过:)
