I am getting an error on jruby (linux) when installing the "trinidad_diagnostics_extension" gem (though this question is not about trinidad). A chain of dependencies is generating the error:
- "trinidad_diagnostics_extension" depends on "jruby-lint >= 0.3.0"
- "jruby-lint >= 0.3.0" in turn depends on "nokogiri >= 1.5.0.beta.4"
- Before attempting to install "trinidad_diagnostics_extension", the relevant part of my gem list looks like this:
$gem list nokogiri (1.5.9 java) jruby-lint (0.4.1)
As you can see, the needed dependencies seem already to be met. Nonetheless,
after adding gem 'trinidad_diagnostics_extension' to my Gemfile and then
running jruby -S bundle install, the bundler attempts to install nokogiri
(1.6.0.rc1), and during this installation fails with the following error:
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
... bunch of omitted output here
nokogiri.c:42:18: fatal error: util.h: No such file or directory
compilation terminated.
make: *** [nokogiri.o] Error 1
Gem files will remain installed in /home/jg/.rvm/gems/jruby-1.7.3/gems/nokogiri-1.6.0.rc1 for inspection.
Results logged to /home/jg/.rvm/gems/jruby-1.7.3/gems/nokogiri-1.6.0.rc1/ext/nokogiri/gem_make.out
- Why is bundler trying to install nokogiri when that dependency is already met?
- How can I fix this? Successfully installing nokogiri 1.6 or making the trinidad extension aware that 1.6 does not need to be installed would both be fine solutions.
In case it's relevant I have JRUBY_OPTS=-Xcext.enabled=true
UPDATE
I was able to get it work by first installing the gem outside of bundler:
jruby -S gem install trinidad_diagnostics_extension
And then the bundle command worked fine, since it was already installed. So I got it working by I am still confused by why I had to install it outside of bundler and why that would matter, and would like some insight if anyone has it.
