在macOSBigSur上安装ReactNative时出现“未定义符号:Swift.ExpressibleByFloatLiteral的协议描述符”问题

我试图在我的系统上安装 React Native,但发现它无法安装该模板错误所需的 CocoaPods 依赖项。

sudo arch -x86_64 gem install ffi修复了这个问题,但最终出现event-config.h" file not found错误。

我将 pod 文件中的更改后的鳍状肢版本更改为use_flipper!({'Flipper'=>'0.76.0'}),然后我遇到了上面提到的错误。对此问题的任何帮助将不胜感激。

node version : 15.10.0
react-native version: 0.63.4
Xcode version: 12.4

错误说明如下:

回答

如果您使用的是 M1 mac,则需要排除架构 arm64。

还要在 pod 文件的末尾添加此代码

post_install do |installer|
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings["ONLY_ACTIVE_ARCH"] = "NO"
      end
    end
  end

执行 pod install,清理构建文件夹并重新启动构建,它将解决问题。

对我真正有用的是,只添加这个排除的架构,你会没事的,当然如果你使用的是带有 M1 的 Mac
