【问题描述】：

我在我的 Gemfile 中添加了一些 gem，特别是 activerecord、sinatra-activerecord、sqlite3、shotgun 和 tux。当我运行“捆绑安装”时，我收到了这个奇怪的错误，似乎没有任何关于它的 Google 信息。这是我得到的错误：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

/usr/local/rvm/rubies/ruby-2.1.1/bin/ruby extconf.rb 

make "DESTDIR=" clean

make "DESTDIR="

make failed, exit code 69

Gem files will remain installed in /usr/local/rvm/gems/ruby-2.1.1/gems/bond-0.5.1 for inspection.

An error occurred while installing bond (0.5.1), and Bundler cannot continue.
Make sure that `gem install bond -v '0.5.1'` succeeds before bundling.

然后我运行建议

gem install bond -v '0.5.1'

然后得到这个：

Building native extensions.  This could take a while...
ERROR:  Error installing bond:

【解决方案1】：

也许这个问题与最近的 XCode 更新有关。在 XCode 更新后，您需要执行以下步骤：

打开 Xcode 并接受许可协议
重新安装命令行工具。

第二步似乎取决于您的操作系统版本。如果xcode-select --install 不起作用，请尝试在/System/Library/CoreServices 中启动Install Command Line Developer Tools 应用程序。

重新安装命令行工具后尝试重新运行bundle install。
