I'm getting "Error 403" when installing rails

Question

I'm trying to install rails -v 5.2.2 on wsl ubuntu 18.04. Im met with following error:

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    bad response Forbidden 403 (https://api.rubygems.org/quick/Marshal.4.8/nokogiri-1.13.3-x64-unknown.gemspec.rz)

I'm relatively new to bash and I'm not sure what to do at this point, as google failed me. Help? :)

Answer 1

I had the same issue with -v 5.2.3. What worked for me was updating RubyGems with:

gem update --system

Then again:

gem install rails --version 5.2.3 

and no issues this time.
