rake db:migrate 返回“rake: 是目录”吗？
我已经寻找这个问题的答案一周了，但还没有找到。我正在运行 Mac OS 10.5.8（如果相关的话）。
我正在尝试执行 Peepcode 教程“Meet Rails 3”，但是当我运行命令行 user$ rake db:migrate 时，我收到以下错误消息：
/usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake: Is a directory - /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake (Errno::EISDIR)
from /usr/local/bin/rake:19:in `load'
from /usr/local/bin/rake:19
我在 ruby.pastebin.com 没有答案。感谢任何愿意帮助有抱负的开发人员的人。谢谢。
I've been searching for the answer to this question for a week, but haven't found one. I'm running Mac OS 10.5.8 if that's relevant.
I'm trying to do the Peepcode tutorial "Meet Rails 3" but when I run the command line user$ rake db:migrate I get the following error message:
/usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake: Is a directory - /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake (Errno::EISDIR)
from /usr/local/bin/rake:19:in `load'
from /usr/local/bin/rake:19
I found the exact same error at ruby.pastebin.com with no answer. Thanks to anyone willing to help out an aspiring developer. Thanks.

看起来您正在使用 Mac OS X 附带的默认安装的 ruby 解释器。我的建议是使用 RVM< /a> 安装/管理您的 gem 位置。我还没有读过/看过“Meet Rails 3”的内容，所以我不确定他们在提倡什么，但我可以根据经验说，RVM 可以让这些类型的问题消失。
It looks like you are using the default install of the ruby interpreter that came with Mac OS X. My suggestion would be to use RVM to install/manage your gem locations. I haven't read/watched the "Meet Rails 3" stuff, so I am not sure what they are advocating, but I can speak from experience that RVM makes these types of issues go away.
