Over the last week, on a few gem install or gem update operations, I've received an error similar to these:
ERROR: While generating documentation for sinatra-1.3.1 ... MESSAGE: error generating C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/doc/sinatra-1.3.1/rdoc/README_de_rdoc.html: incompatible encoding regexp match (UTF-8 regexp with IBM437 string) (Encoding::CompatibilityError)
similarly:
ERROR: While generating documentation for rest-client-1.6.7 ... MESSAGE: error generating C:/RailsInstaller/Ruby1.9.2/lib/ruby/gems/1.9.1/doc/rest-client-1.6.7/rdoc/README_rdoc.html: incompatible encoding regexp match (UTF-8 regexp with IBM437 string) (Encoding::CompatibilityError)
and possibly one other place. I've read up on this but don't find a solution for code I did not write and data I don't control. Any idea how to fix this?
I had a similar problem on Ubuntu and updating rubygems itself solved the problem for me. You can do that by entering the following at the command line:
gem update --system
Also, you can always skip the doc generation by using:
--no-rdoc --no-ri
when installing the gem.
On Windows, this worked for me:
> set RDOCOPT="--encoding=UTF-8"
> gem install heroku
michael.rp almost had it, but no quotes on the environment string for Windows. The same solution for Linux appears in the link supplied by jerry. For Windows:
set RDOCOPT=--encoding=UTF-8
I put this in the RubyInstaller\Ruby1.9.3\setup_environment.bat
file so it is always there.
