For gems with executables ruby installs a wrapper file into the executable directory by default. This can be overridden with the --no-wrappers option. The wrapper allows you to choose among alternate gem versions using _version_. For example `rake _0.7.3_ --version` will run rake version 0.7.3 if a newer version is also installed. Gem Dependency Files ==================== RubyGems can install a consistent set of gems across multiple environments using `gem install -g` when a gem dependencies file (gem.deps.rb, Gemfile or Isolate) is present. If no explicit file is given RubyGems attempts to find one in the current directory. When the RUBYGEMS_GEMDEPS environment variable is set to a gem dependencies file the gems from that file will be activated at startup time. Set it to a specific filename or to "-" to have RubyGems automatically discover the gem dependencies file by walking up from the current directory. NOTE: Enabling automatic discovery on multiuser systems can lead to execution of arbitrary code when used from directories outside your control. Extension Install Failures ========================== If an extension fails to compile during gem installation the gem specification is not written out, but the gem remains unpacked in the repository. You may need to specify the path to the library's headers and libraries to continue. You can do this by adding a -- between RubyGems' options and the extension's build options: $ gem install some_extension_gem [build fails] Gem files will remain installed in \\ /path/to/gems/some_extension_gem-1.0 for inspection. Results logged to /path/to/gems/some_extension_gem-1.0/gem_make.out $ gem install some_extension_gem -- --with-extension-lib=/path/to/lib [build succeeds] $ gem list some_extension_gem *** LOCAL GEMS *** some_extension_gem (1.0) $ If you correct the compilation errors by editing the gem files you will need to write the specification by hand. For example: $ gem install some_extension_gem [build fails] Gem files will remain installed in \\ /path/to/gems/some_extension_gem-1.0 for inspection. Results logged to /path/to/gems/some_extension_gem-1.0/gem_make.out $ [cd /path/to/gems/some_extension_gem-1.0] $ [edit files or what-have-you and run make] $ gem spec ../../cache/some_extension_gem-1.0.gem --ruby > \\ ../../specifications/some_extension_gem-1.0.gemspec $ gem list some_extension_gem *** LOCAL GEMS *** some_extension_gem (1.0) $ EOF end def usage # :nodoc: "#{program_name} GEMNAME [GEMNAME ...] [options] -- --build-flags" end def check_install_dir # :nodoc: if options[:install_dir] and options[:user_install] then alert_error "Use --install-dir or --user-install but not both" terminate_interaction 1 end end def check_version # :nodoc: if options[:version] != Gem::Requirement.default and get_all_gem_names.size > 1 then alert_error "Can't use --version w/ multiple gems.
