Bug #3677: unable to run certain gem binaries' in windows 7

• Status: Closed
• Assignee: nobu (Nobuyoshi Nakada)

• ruby -v: ruby 1.9.3dev (2010-07-22 trunk 28717) [i386-mingw32]

Currently:

C:\installs\ruby_trunk_installed\bin>rake -T
C:/installs/ruby_trunk_installed/lib/ruby/1.9.1/rubygems.rb:340:in bin_path': can't find executable rake for rake-0.8.7 (Gem::Exception) from C:/installs/ruby_trunk_installed/bin/rake:19:in '

The problem seems to not have existed with 1.9.2 preview 3. Also doesn't seem to be a problem on XP, which is rather odd.
The problem exists on 1.9.2 RC1, and on trunk (as noted here).

Thanks.

Looking into bin/rake I see is not the gem based stub, but is the bin/rake found inside the gem.

After doing "gem install rake":

C:\Users\Luis\Projects\oss\oci\rubyinstaller\sandbox\ruby19_mingw>rake --version
C:/Users/Luis/Projects/oss/oci/rubyinstaller/sandbox/ruby19_mingw/lib/ruby/1.9.1/rubygems.rb:340:in bin_path': can't find executable rake for rake-0.8.7 (Gem::Exception) from C:/Users/Luis/Projects/oss/oci/rubyinstaller/sandbox/ruby19_mingw/bin/rake:19:in '

So the issue is not that, but that the gem_prelude is not loaded properly?

This happens with trunk and with 1.9.2 branch.

Good catch. It only occurs after doing a "gem install rake"
and it appears that it is also reproducible on XP, once you do that.

Also able to reproduce it in Linux:

Installing the gem outside Ruby (using GEM_HOME and GEM_PATH) do not
generate the issue.

Appears that deleting your installation's "rake.gemspec" file is enough.

Perhaps rubygems doesn't know how to remove the previous version .gemspec file, since it lacks any version info?

Hello,

Bosko (one of RubyInstaller contributors) shed some light on this issue in our group:

http://groups.google.com/group/rubyinstaller/msg/249a08a3f635bf72

Going to quote it here:

"Problem is that during installation in rbinstall.rb line
516 default .gemspec files are created for rake, rdoc and minitest. These
files are saved by default in lib/ruby/gems/1.9.1/specifications. If
everything is left by default other gems will be installed there too (that's
why this problem can occur on Linux too). Since these specifications do not
contain default_executable and executables sections invoking them results in
error. If rvm is used on Linux error will not occur because gems will be
installed in different folder and load path is set to that folder and
rake.gemspec and rake-0.8.7.gemspec will not both be loaded. Later one has
correct sections for default_executable and executables thus everything will
work correctly.

Unfortunately in our RubyInstaller both of these files will be in the same
directory and that's the reason why reinstalling rake doesn't help unless
rake.gemspec is deleted since this specification is loaded after
rake-0.8.7.gemspec and overrides it. I'm not sure what would be the best
approach to fix this problem. Either not to bundle rake with Ruby or to
create correct .gemspec file. We can also set different installation
directory too like rvm does."

I believe this is important to be fixed before 1.9.2 release gets out. Not all the users will be using RVM to manage their Ruby installations.
