在 NTFS 分区上创建新的 Rails 应用程序时如何消除错误？

Question

当我在 NTFS 分区上创建新的 Rails 应用程序时，我收到了一堆错误。不过，使用相同的配置，当我在位于 ext4 格式分区的主目录中创建项目时，我不会收到任何错误。
这是我得到的。

$ rails new project
      create  
      create  README
      create  Rakefile
      [...]
      create  public/index.html
      create  public/robots.txt
      create  script
      create  script/rails

我通过rvm安装了rails 3.1.3。

$ rvm list
rvm rubies
=> ruby-1.9.3-p0 [ x86_64 ]
   ruby-1.9.2-p290 [ x86_64 ]
   ruby-1.9.2-p180 [ x86_64 ]

这是我的一般配置。

$ rails -v
Rails 3.1.3
$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]
$ rvm -v
rvm 1.9.2
$ bundle -v
Bundler version 1.0.21
$ gem -v
1.8.11

我使用 Ubuntu 10.10。
