Hi,can anyone help me on this. When installing any gem ,error the below error is encountered. ERROR: While executing gem ... (Encoding::CompatibilityError) incompatible character encodings: UTF-8 and ASCII-8BIT The error is observed only when Ruby 2.3.3 is installed and the issue is observed only on few PC's. PC Configuration: Windows 7 Professional Service Pack 1 Thanks, Sai Kiran.

Quite an annoying error. What Encoding do you use? You can find out via irb for example. Start it, then: "abc".encoding.to_s For me it is "ISO-8859-1". The error that you get is a bit unusual because ASCII-8BIT should not be there. Does your system perhaps default to it? If you are not using UTF-8, rubygems should default to it. You can also try to install a gem locally, by downloading; and if it still fails, you can try via setup.rb which still works (http://i.loveruby.net/en/projects/setup/) but I would first try to find out what is wrong with your encoding. Other ruby people on windows do not seem to get this error as easily so perhaps something is unique to your system. What is the language that you use on your machine btw? I assume it may be some non-standard, somewhat exotic language.

Hi Robert H., Thanks for quick response. Ruby Version: C:\Users\snemala>ruby -v ruby 2.3.3p222 (2016-11-21 revision 56859) [i386-mingw32] Encoding: C:\Users\snemala>irb irb(main):001:0> "abc".encoding.to_s => "IBM437" Encoding of my PC is IBM437 I think,the issue(Incompatible error) is observed on when ruby tries to go to web and download the appropriate .gem file. I have tried to installing gems locally by placing the .gem files in C:\Ruby193\lib\ruby\gems\1.9.1\cache and then executing command gem install --force --local *.gem then gems were installed successfully. But when i have tried to update gems using - gem update Again the same error was encountered.
