Not able to install padrino gem

Question

I'm getting this error when I'm trying to install padrino/sinatra gem.

$ gem install padrino
ERROR:  While executing gem ... (Gem::Package::FormatError)
    package metadata is missing in linecache19-0.5.13.gem

RUBYGEMS VERSION: 2.4.6
RUBY VERSION: 2.1.2 (2014-05-08 patchlevel 95) [x86_64-darwin14.0]

Tried the steps mentioned in this link as suggested. But still I'm getting same errors in following those steps.

Yes, I'm getting the same error no matter what gem I install. `$gem install linecache19 ERROR: While executing gem ... (Gem::Package::FormatError) package metadata is missing in linecache19-0.5.13.gem` — Nikhil Patil, Feb 28 '15 at 14:15

I checked that thread. But rubyforge.org is moved to rubygems.org and I couldn't find linecache19-0.5.13 on rubygems.org. The latest one available there is linecache19-0.5.12. I downloaded that gem, tried installing it and again I got the same error. — Nikhil Patil, Mar 01 '15 at 06:15

You probably want to add an -s to your curl, otherwise the output from the download progress could end up in the gem file, and confuse rubygem. When I download a gem using curl, I use:

curl -LsOw ${url_effective} https://docs.rubygems.org/downloads/gem-version.gem

That final argument (-w %{url_effective}) just outputs the final URL after all of the redirects. Sometimes helpful.
