ruby 编码::未定义转换错误

大家好，我正在尝试运行我的第一个 ror 应用程序 并得到以下错误：

C:\Sites\myapp>rails server
Could not find gem 'tzinfo-data (>= 0) x86-mingw32' in the gems available on thi
s machine.
Run `bundle install` to install missing gems.

所以我写：

 C:\Sites\myapp>bundle install
    DL is deprecated, please use Fiddle
    Fetching gem metadata from https://rubygems.org/..........
    Resolving dependencies...

Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3 read
server certificate B: certificate verify failed (https://rubygems.org/gems/rake-
10.4.2.gem)
An error occurred while installing rake (10.4.2), and Bundler cannot continue.
Make sure that `gem install rake -v '10.4.2'` succeeds before bundling.

最后：

C:\Sites\myapp>gem install rake -v '10.4.2'
ERROR:  While executing gem ... (Encoding::UndefinedConversionError)
    U+041D to IBM437 in conversion from UTF-16LE to UTF-8 to IBM437

如您所见，我使用的是 windows.Windows 8 32 位。

我找到了这个答案：在此输入链接描述 https://stackoverflow.com/questions/27325245/ruby-rails-gem-install-error-error-while-executing-gem-encodingundefi

还有其他办法吗？

使用： 1.rubyinstaller-1.9.3-p551.exe 而不是 ruby​​installer-2.1.6.exe 或 ..
2.默认目录C:\Ruby193\
我刚刚在 win-7 32bit 上解决了这个问题。
