[英]Rake des not know how to build task 'compile', how to track this error?
I get the error "Don't know how to build task 'compile'". 我收到错误消息“不知道如何构建任务'编译'”。 Im still new to ruby, but but all those traces seem to point to code i didnt wrote, so what should i do on this error?
我对ruby还是陌生的,但是所有这些痕迹似乎都指向我未编写的代码,因此我应该如何处理该错误?

this is the Rakefile: 这是Rakefile:
require 'bundler/gem_tasks' require 'rake' require 'rake/extensiontask' $myDir = File.dirname(__FILE__) require $myDir + '/lib/Q/console.rb' require $myDir + '/lib/Q/version.rb' require $myDir + '/lib/Q/rakeoverride.rb' require $myDir + '/lib/Q/filetools.rb' # this just prints out a header and gems version number puts Q::Console.txHead('Q-Pool Ruby Extension Q V' + Q::VERSION) # load specifiation from gemspec and create # a task for every extension file in # executables. spec = Gem::Specification.load('Q.gemspec') spec.executables.each do |f| Rake::ExtensionTask.new('Q', spec) do |ext| # extension file is *.so, so we need # to chop the extension to get the name ext.name = f.gsub(/\.so$/,'') ext.tmp_dir = 'tmp' ext.lib_dir = 'bin' end end # clean environment by removing old binaries override_task :clean do puts Q::Console.txNote('cleaning...') clear_tmp begin Rake::Task["clean:original"].invoke puts Q::Console.txConfirm('...cleaned!') rescue puts Q::Console.txAlert('could not clean: ' + $!.to_s) exit end end # initialize directory structure task :init do FileCheckCreateDirectory($myDir + '/bin') FileCheckCreateDirectory($myDir + '/tmp') end # compile module and install to lib override_task :compile do puts Q::Console.txNote('compiling...') begin Rake::Task["compile:original"].invoke puts Q::Console.txConfirm('...compiled!') rescue Exception puts Q::Console.txAlert('could not compile: ' + $!.to_s) exit ensure clear_tmp puts end end # show commands task :help do show_help end # build module and install task :build => [:init, :clean, :compile] Bundler::GemHelper.install_tasks # remove any temporary files def clear_tmp FileUtils.rm_rf(Dir.glob($myDir + '/tmp/*')) end # display help screen def show_help Q::Console.out(Q::Console.txCode('build') + ' performs init, clean and compile.') Q::Console.out(Q::Console.txCode('clean') + ' removes any old binaries from temp-dir.') Q::Console.out(Q::Console.txCode('compile') + ' compiles binaries.') Q::Console.out(Q::Console.txCode('help') + ' enlists rake-commands (this page).') Q::Console.out(Q::Console.txCode('init') + ' creates gems directory structure.') puts end
Ok, this error-message was really of little use at all… 好的,这个错误消息实际上根本没用……
The problem was that Gem::Specification.executables was empty due to a not matching regex in gemspec. 问题是由于gemspec中的正则表达式不匹配,Gem :: Specification.executables为空。 As I iterate though it (see Rakefile), there was no extensiontask build, hence the misleading error.
当我进行迭代时(请参阅Rakefile),没有扩展任务构建,因此产生了误导性错误。
