找不到耙子

rake rubygems ruby

    嘿,我玩过 bundler 还有一些宝石,现在我不能用了 rake 不再

    如果我执行简单的db:migrate,我会得到以下错误: 

    mac:app antpaw$ rake db:migrate
/usr/local/lib/ruby/site_ruby/1.9.1/rubygems.rb:335:in `bin_path': can't find executable rake for rake-0.8.7 (Gem::Exception)
 from <internal:gem_prelude>:282:in `method_missing'
 from /usr/local/bin/rake:19:in `<main>'

    但如果我有,Rake就列在名单上了 gem list . 我使用的是Rails 3.0.0beta4、Bundler 1.0.0.beta.5和Ruby1.9.2dev。

    编辑发布我的 export 

    mac:trickpipe antpaw$ export

mac:trickpipe antpaw$ which ruby

mac:trickpipe antpaw$ ruby -v
ruby 1.9.2dev (2010-07-02 revision 28524) [x86_64-darwin10.2.0]

    好的,我试过了,看看错误消息是如何变化的: 

    mac:trickpipe antpaw$ export GEM_HOME="/usr/local/lib/ruby/gems"
mac:trickpipe antpaw$ rake about

    我很确定您没有正确设置路径环境。 /usr/local/lib/ruby/site_ruby/1.9.1/ 是Mac OS X附带的Ruby解释器的默认包文件夹——垃圾。当你说你(假设)使用Ruby1.9.2dev时,这个路径是错误的。请放弃 export 在shell中并发布结果。另外,请发布Ruby1.9.2dev和捆绑文件夹的安装-/pathes。

    编辑1:

    好的,快速修复您的问题: export GEM_HOME="/path/where/your/gems/reside" 任选地 export GEM_PATH="/path/where/your/gems/reside" 任选地 export PATH="/path/where/your/gems/reside:$PATH" . 只有按这个顺序!尝试一个,当它仍然不工作时,继续下一个导出。

    请注意,这可以解决您的问题,但是要使bundler环境与rails f.e一起工作,您必须更改rails应用程序的配置,以显式地使用自定义bundler gem环境。我前段时间读到rails3将包含这些选项;如果是这样(我不知道rails3),请检查您的那些命令。

    注意:把邦德勒放在一边,用RVM代替。它的功能更强大,更成熟,并且具有更大的灵活性(尤其是在与gemes一起处理多个口译员时)。

    仅供参考,如果您使用MacPorts安装Ruby1.9.2,我遇到了这样的问题: 

    /opt/local/lib/ruby1.9/1.9.1/rubygems.rb:340:in `bin_path': can't find executable rake for rake-0.8.7 (Gem::Exception)
from /opt/local/bin/rake:19:in `<main>'

    修复方法是进入/opt/local/lib/ruby1.9/gems/1.9.1/specifications并删除“rake.gemspec”

    就是这样…花了很长时间才发现,但是,效果很好

    我对房车也有同样的问题 ("warning: already initialized constant RAKEVERSION") 等等。

    我正在使用gemeset(“rails”)进行开发,但我注意到 BUNDLE_PATH 不是指这个宝石 (.rvm/gems/ruby-1.9.2-p0@rails); 相反,它指向了全球 (.rvm/gems/ruby-1.9.2-p0).

    我修理了 捆绑路径 要使用轨道,宝石和耙子现在可以正常工作了。希望它有帮助。

    这是1.9.2p0中的错误 http://betterlogic.com/roger/2010/11/ruby-1-9-2-rake-woe/
