Bundle install: ERROR: Failed to build gem native extension. nio4r gem
我目前正在使用以下项目进行项目：
- rvm 1.26.11
- ruby 2.2.1p85
我尝试 运行 bundle install 但不断收到以下错误：
Gem::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 运行ning gem install nio4r -v '1.0.0':
Building native extensions. This could take a while...
ERROR: Error installing nio4r:

当我尝试 运行ning bundle update:

Make sure that `gem install eventmachine -v '1.0.3'` succeeds before bundling.
我也试过那个命令，没有结果。
我也尝试更改 Ruby 版本：
rvm use 2.2.1 2.2.0 2.0.0 和 运行 上面的命令，但它没有改变任何东西

如果您使用 Ruby 2.2.1
，请更新至版本 1.0.4
我解决了它：
sudo apt-get install libmysqlclient-dev

sudo apt-get install libev-dev
rvm use 2.0.0
Reboot pc
如果我 运行 rails -v 显示我：

现在我可以Bundle install
我认为 rails 版本有冲突。我不知道为什么，也许有人可以解释我。
如果您在 Mac OSX 以上版本 10.11.x 上工作，以下方法对我有用：
gem install nio4r -v '1.1.0' -- with-cflags="-std=c99"
bundle config build.nio4r --with-cflags="-std=c99"
