我目前正在开发一个项目，使用：
我尝试运行
bundle installGem::Ext::BuildError: ERROR: Failed to build gem native extension.
以及以下：
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.
当我尝试跑步时
gem install nio4r -v '1.0.0'Building native extensions. This could take a while...
ERROR: Error installing nio4r:
ERROR: Failed to build gem native extension.
当我尝试跑步时
bundle updatePlease make sure you have the correct access rights
and the repository exists.

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.
我也尝试过该命令，但没有结果。
我也尝试过更改 Ruby 版本：
rvm use 2.2.12.2.02.0.0编辑：

Gem files will remain installed in /home/adrian/.rvm/gems/ruby-2.2.1/gems/nio4r-1.0.0 for inspection. Results logged to /home/adrian/.rvm/gems/ruby-2.2.1/extensions/x86_64-linux/2.2.0/nio4r-1.0.0/gem_make.out 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.
如果您使用的是 Mac OSX 以上版本
10.11.xgem install nio4r -v '1.1.0' -- with-cflags="-std=c99"
我解决了这个问题：
sudo apt-get install libmysqlclient-dev
sudo apt-get install libpq-dev
sudo apt-get install libsqlite3-dev
sudo apt-get install libev-dev
rvm use 2.0.0
Reboot pc
如果我跑步
rails -v现在我可以做
Bundle install我认为 Rails 版本存在冲突。我不知道为什么，也许有人可以解释我。
bundle config build.nio4r --with-cflags="-std=c99"
bundle install
对我有用
如果您使用的是 Ruby 2.2.1，请更新到版本 1.0.4
运行以下命令后，可以在 macOS Sierra (10.12.2) 上正常运行：
xcode-select --install
在我之前：
An error occurred while installing nio4r (1.2.1), and Bundler cannot continue.
设置捆绑配置对我不起作用...
如果您最近更新了 Xcode，请确保实际运行该应用程序并接受服务条款。
在我的捆绑错误中，我得到了
You have to install development tools first.这发生在我身上，这是因为安装了新版本的 XCODE 并且我没有接受新的条款和条件。查看 mkmf.log 显示以下内容：
Agreeing to the Xcode/iOS license requires admin privileges, please run “sudo xcodebuild -license” and then retry this command.我在尝试安装
