我正在将一个 Rails 站点上传到 bluehost，这是一个在我的本地计算机上运行的站点。不过，我无法将其配置为在 bluehost 上运行。这是我得到的错误：
[warn] [client 74.220.197.129] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[error] [client 74.220.197.129] Premature end of script headers: dispatch.fcgi ./../config/../vendor/rails/railties/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. Use #requirement
./../config/../vendor/rails/railties/lib/initializer.rb:271:in `require_frameworks':
RubyGem version error: rack(1.1.0 not ~> 1.0.1) (RuntimeError) from ./../config/../vendor/rails/railties/lib/initializer.rb:134:in `process' from ./../config/../vendor/rails/railties/lib/initializer.rb:113:in `send' from ./../config/../vendor/rails/railties/lib/initializer.rb:113:in `run' from ./../config/environment.rb:11 from dispatch.fcgi:21:in `require' from dispatch.fcgi:21
我已经安装了 rack 1.0.1，并且正确地重命名 .htaccess 给了我一个文件的索引列表。这似乎是一个 .htaccess 错误。这是我的 .htaccess 文件：
AddHandler fcgid-script .fcgi
AddHandler cgi-script .cgi
# For security reasons, Option followsymlinks cannot be overridden.
# Options +FollowSymLinks +ExecCGI
Options +SymLinksIfOwnerMatch +ExecCGI
RewriteEngine On
RewriteRule ^$ index.html [QSA]
RewriteRule ^([^.]+)$ $1.html [QSA]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
ErrorDocument 500 /500.html
#ErrorDocument 500 "<h2>Application error</h2>Rails application failed to start properly"
我究竟做错了什么？
