sudo bundle 导致“找不到捆绑程序”错误

Question

我有bundle exec 工作正常，但是当我尝试执行sudo bundle exec 时，我有Could not find 'bundler' (>= 0) 错误。

这是完整的错误消息。

smcho@macho appname> sudo bundle exec unicorn -c config/unicorn.rb -E production -D
/Users/smcho/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'bundler' (>= 0) among 11 total gem(s) (Gem::LoadError)

    from /Users/smcho/.rvm/gems/ruby-2.2.3/bin/ruby_executable_hooks:15:in `<main>'

我找到了许多与此问题相关的问题/答案，但似乎没有任何效果。

• Using $ sudo bundle exec ... raises 'bundle: command not found' error
  • 我尝试了这篇文章的答案，但没有任何效果。无论如何，我的错误信息不是bundle: command not found。
• Why is sudo: bundle command not found?
  • $ echo 'echo $PATH' | sh 和 $ echo 'echo $PATH' | sudo sh 的结果相同

要使用bundle命令，需要先安装bundler：

sudo gem install bundler

然后你就可以使用bundle命令了：

sudo bundle exec . . .
