“未定义符号:Swift.ExpressibleByFloatLiteral 的协议描述符"；在 macOS Big Sur 上安装 React Native 时出现问题 [英] "Undefined symbol: protocol descriptor for Swift.ExpressibleByFloatLiteral" issue while installing react native on macOS Big Sur

问题描述

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.

I was trying to install React Native on my system, and found that it failed to install CocoaPods dependencies which is required by that template error.

sudo arch -x86_64 gem install ffi 修复了这个问题，但最终出现了 event-config.h"找不到文件 错误.

sudo arch -x86_64 gem install ffi fixed this issue but ended up with event-config.h" file not found error.

我将 pod 文件中已更改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.

I changed the changed the flipper version in pod file to use_flipper!({'Flipper'=>'0.76.0'}) and then I reached to the error mentioned above. Any help on this issue would be appreciated.

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

错误描述如下:

推荐答案

如果您使用的是 M1 mac，则需要排除架构 arm64.

You need to exclude architecture arm64 if you are using M1 mac.

也在 pod 文件的末尾添加这段代码

Also add this code at the end of the pod file

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 build 文件夹并重新启动 build 即可解决问题.

Do pod install, Clean the build folder and restart the build it will resolve the issue.
