我正在学习 ruby on rails，所以我的问题可能非常基础。我在 Windows 8 上使用 Ruby 2.0.0 和 rails 4.0。首先，我试图在 rails 上安装 ruby，但我遇到了很多错误，例如：
unable to convert from ascii-8bit to utf8 logo remix.gif, skipping
分期付款是成功的，但我认为它错过了一些图像。我在网上搜索过，很多人说 MAC 机器，可以通过将 .bash_profile 添加到 \users\username 来修复，内容为：
export LC_CTYPE=en_US.UTF-8
export LANG=en_US.UTF-8
unset LC_ALL
但是如何在 Windows 8 机器上解决这个问题？

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
我错过了一些分期付款吗？请帮忙。
