我目前正在使用以下项目：
> rvm 1.26.11
> ruby 2.2.1p85
我试图运行捆绑安装,但不断收到以下错误：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
和以下：
An error occurred while installing nio4r (1.0.0),and Bundler cannot continue. Make sure that `gem install nio4r -v '1.0.0'` succeeds before bundling.
当我尝试运行gem安装nio4r -v’1.0.0’：
Building native extensions. This Could take a while... ERROR: Error installing nio4r: ERROR: Failed to build gem native extension.
当我尝试运行捆绑更新：
Please make sure you have the correct access rights and the repository exists. retrying git clone 'git@github.com:kshmir/requirejs-rails.git' ....* Git error: command `git clone 'git@github.com:kshmir/requirejs-rails.git'.... has Failed
当我尝试运行bundle update nio4r时：
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.... An error occurred while installing eventmachine (1.0.3),and Bundler cannot continue. Make sure that `gem install eventmachine -v '1.0.3'` succeeds before bundling.
我也试过这个命令,没有结果.
我也试过改变Ruby版本：
rvm使用2.2.1 2.2.0 2.0.0并运行上面的命令,但不会改变任何内容
编辑：
运行bundle的输出安装日志：
