Question

Bower install fails with 502 - Bad Gateway when downloading bower packages.

For example bower install for ember library gives following response in command line.

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

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.

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 :)
