EINVRES Request to https://bower.herokuapp.com/packages/ember failed with 502

When http://bower.herokuapp.com/ is accessed directly from URL it gives the following message.

This Bower version is deprecated. Please update it: npm install -g bower. The new registry address is https://registry.bower.io

Answer 1

When using asp.net core then should change something like this. bowerrc.json you can find inside project folder.

  {
     "registry": "https://registry.bower.io",
     "directory": "wwwroot/lib"
  }

Answer 2

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.

Users working on old bower versions can update the .bowerrc file with the following data.

{
  "registry": "https://registry.bower.io"
}

.bowerrc file can be located at the same folder where bower.json and bower_components folder is located. If it is not present already, you can make one.

Answer 3

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 :)

Answer 4

Simplest solution is to just upgrade bower to latest version

If installed via NPM:
