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
回答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.

Simplest solution is to just upgrade bower to latest version
If installed via NPM:
npm i -g bower

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"
}
回答4:
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 :)
回答5:
echo '{"registry": "https://components.bower.io","directory": "wwwroot/lib"}' > .bowerrc
