嘿,我玩耍捆绑和一些宝石,现在我不能使用耙子了
如果我做一个简单的db：migrate我得到这个错误：
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>'
如果我做宝石列表,耙子是列出的. im使用rails 3.0.0beta4,bundler 1.0.0.beta.5和ruby 1.9.2dev.
EDIT发布我的出口

好的,我试过了,看看错误msg是如何变化的：

现在用rvm：

解决方法
我很确定你没有正确设置你的路径环境.
/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.当你说你(假设)使用Ruby 1.9.2dev这个路径是错误的.请在shell中删除导出并发布结果.此外,请发布您的安装/打开Ruby 1.9.2dev和您的捆绑文件夹.

编辑1：
好的,您的问题的quickfix：export GEM_HOME =“/ path / where / your / gems / residence”,并可选地导出GEM_PATH =“/ path / where / your / gems / residence”,并可选地导出PATH =“/ path / where /你/宝石/驻留：$PATH”.只有在这个顺序！尝试一个,当它仍然不工作继续下一个导出.
请注意,这应该解决您的问题,但是要使Bundler环境与rails f.e您必须更改Rails应用程序的配置,以明确使用您的自定义BUndler gem环境.之前我读过Rails3将包含这个选项;在这种情况下(我不知道Rails3)检查你的这些命令.
P.s：将Bundler放在一边,并使用RVM.它更强大,更成熟,并且允许更多的灵活性(特别是在与gemsets一起处理多个口译员时).
