在Digital Ocean Droplet上设置rbenv并安装bundler，我无法通过rbenv将填充程序添加到填充程序中或能够运行rbenv exec bundle install
版本：
Ubuntu 14.04
rbenv 0.4.0-98-g13a474c
deploy$ gem -v
2.2.2
deploy$ ruby -v
ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux]
deploy$ rbenv version
2.1.2 (set by /home/deploy/.rbenv/version)
我这样做了：
deploy@myip:~$ sudo gem install bundler
Fetching: bundler-1.6.3.gem (100%)
Successfully installed bundler-1.6.3
1 gem installed
deploy@myip:~$ which bundler
/usr/local/bin/bundler
deploy@myip:~$ rbenv rehash
deploy@myip:~$ ls .rbenv/shims
erb gem irb rake rdoc ri ruby testrb
我希望在rbenv rehash之后在垫片中看到捆绑包。我还希望rbenv exec bundle install --binstubs能够立即运行而不会出现错误。现在它给了我一个无命令错误：
deploy@myip:~/.rbenv/shims$ rbenv exec bundle install --binstubs
rbenv: bundle: command not found
我怀疑这个问题与我的RubyGems配置有关，但是看不出它有什么问题。看起来它在rbenv中执行安装和可执行文件。

想法？思考？给我的东西尝试？我很困难......
