当我在我的rails 5项目上运行bundle install时，我在gems上遇到了许多错误，这些错误似乎有原生扩展。下面是其中一个gem的输出的顶部：

Installing nio4r 1.2.1 with native extensions

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

我试过很多方法。
this post我尝试了以下建议：

# didn't fix it
bundle config build.nio4r --with-cflags="-std=c99"
bundle

# didn't fix it
xcode-select --install
sudo xcodebuild -license accept
bundle

我还引用了this Go Rails guide，特别是“最终步骤”部分，该部分涉及需要C扩展的gem，但该命令似乎不适用，因为我没有从莫哈韦迁移我的macOS。
在这一点上，我不知道下一步该做什么。最终：看起来这个问题围绕着无法安装需要C扩展的gem。
环境：

• macOS Monterey版本12.2
• 使用rvm与ruby版本2.7.4
• 项目正在使用Rails版本5.0.1
