我正在尝试在商业托管服务上部署网站。 （JustHost.com）
我在运行bundle
# bundle
Fetching gem metadata from https://rubygems.org/........
Fetching gem metadata from https://rubygems.org/..
sudo: unable to stat /etc/sudoers: No such file or directory
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
Gem::Exception: Cannot load gem at [/usr/lib64/ruby/gems/1.9.3/cache/rake-10.3.0.gem] in /home5/<username>/<sitename>
An error occurred while installing rake (10.3.0), and Bundler cannot continue.
Make sure that `gem install rake -v '10.3.0'` succeeds before bundling.
我能够成功运行gem install命令：
# gem install rake -v '10.3.0'
Successfully installed rake-10.3.0
1 gem installed
Installing ri documentation for rake-10.3.0...
Installing RDoc documentation for rake-10.3.0...
但是我得到了重新运行bundle的错误。此外，我不认为我实际上能够安装rake - 我的位置不可写，版本没有变化：
# which rake
/usr/bin/rake
# rake --version
rake, version 0.9.2.2
我也尝试更新我的Gemfile以使用rake 0.9.2.2。但遇到了同样的问题：
# bundle
