ruby-perf不是通过bundler安装的，但可以使用命令行安装

Question

我正在尝试安装ruby-perf。我遇到了一些问题，但在安装ruby-dev之后，它通过控制台运行得很好。

ubuntu@ubuntu-VirtualBox:~/web$ sudo gem install ruby-prof -v '0.13.0'
Fetching: ruby-prof-0.13.0.gem (100%)
Building native extensions.  This could take a while...
Successfully installed ruby-prof-0.13.0
1 gem installed

但是当我运行bundler时，它仍然显示错误。

ubuntu@ubuntu-VirtualBox:~/web$  bundle install

Gem files will remain installed in /home/ubuntu/jruby-1.7.3/lib/ruby/gems/shared/gems/ruby-prof-0.13.0 for inspection.

An error occurred while installing ruby-prof (0.13.0), and Bundler cannot
continue.
Make sure that `gem install ruby-prof -v '0.13.0'` succeeds before bundling.

我也验证了gem是否已安装。

ubuntu@ubuntu-VirtualBox:~/web$ sudo gem list
