Forum: wxRuby invalid gem format on ruby 1.9

Hi,

I have developed a small wxruby app on my old mac using wxruby 2.0.1
on ruby 1.8.6.  I am trying to upgrade now, and have encountered some
problems.

I use rvm to install ruby 1.9.2, then I run gem install wxruby-ruby19
and get the following error:

ERROR:  While executing gem ... (Zlib::DataError)
    invalid literal/lengths set

I use rvm to install ruby 1.9.1, then I run gem install wxruby-ruby19
and get the following error:

ERROR:  Error installing wxruby-ruby19:
  invalid gem format for
/Users/josh/.rvm/gems/ruby-1.9.1-p431/cache/wxruby-ruby19-2.0.1-x86-darwin-9.gem

Finally, I install the stable version of ruby for windows on a windows
box and run gem install wxruby-ruby19 and get the same invalid gem
format for the x86-ming32 gem.

Any help would be much appreciated!

Regards,
Josh

I cannot confirm this. On my machine (64-bit Linux system), the
wxruby-ruby19 gem installs just fine (just tried it). Maybe something
is wrong with your internet connection?

Here are some SHA256 checksums of the gems (Files downloaded from
RubyGems.org):

wxruby-ruby19-2.0.1-x86-mingw32.gem

But note the only one I could test was the
wxruby-ruby19-2.0.0-x86_64-linux.gem file as that’s my system’s
architecture. However, last time I had a Windows on my fingers the
Windows gem worked (~3 Months ago), and since then no new wxRuby
release happened.

Just to be sure: You don’t try to download gems from rubyforge.org, do
you? Although the site should forward to rubygems.org, it’s offline at
the moment, what maybe causes problems. What does

$ gem sources

say?

Thanks.  I updated my rubygems and downloaded again for my Mac and it
works, but I'm still having trouble on the windows machine at work.
It must just be a glitch in the Matrix.

Although not directly helpful, I just thought I would post that I got 
wxruby installed ok on Windows - so it does work (once you remember the 
1.9 version is the one you need).
