Expo Go项目无法接入Firebase，切换React Native CLI遇Gem构建错误求助

一、优先方案：在现有Expo Go项目中接入Firebase #

Expo Go完全支持Firebase集成，无需切换到React Native CLI，步骤如下：

• 安装所需的Firebase Expo库（按需选择）：

  expo install expo-firebase-app expo-firebase-auth expo-firebase-firestore
  

• 前往Firebase控制台创建项目，下载对应平台的配置文件：
  • iOS：GoogleService-Info.plist，放在项目根目录
  • Android：google-services.json，放在项目根目录
• 修改项目根目录的app.json，添加平台配置：

  {
    "expo": {
      "ios": {
        "googleServicesFile": "./GoogleService-Info.plist",
        "bundleIdentifier": "你的iOS包名"
      },
      "android": {
        "googleServicesFile": "./google-services.json",
        "package": "你的Android包名"
      }
    }
  }
  

• 在项目代码中初始化Firebase：

  import { initializeApp } from 'expo-firebase-app';
  
  // 若已配置googleServicesFile，无需手动传入config
  initializeApp();
  

二、React Native CLI环境错误修复（ffi安装失败） #

从错误日志看，核心问题有两个：项目路径包含空格导致make命令解析失败，以及系统缺少libffi依赖。解决步骤：

1. 迁移项目到无空格路径
   原路径/Users/jonnywerthman/Desktop/Dev stuff/...中的空格会导致shell命令解析错误，将项目移动到类似/Users/jonnywerthman/Desktop/DevStuff/personal/90dayz/Dayz90的路径下。

2. 安装系统级libffi依赖

   brew install libffi
   

3. 配置环境变量让Ruby找到libffi

   export LDFLAGS="-L$(brew --prefix libffi)/lib"
   export CPPFLAGS="-I$(brew --prefix libffi)/include"
   export PKG_CONFIG_PATH="$(brew --prefix libffi)/lib/pkgconfig"
   

4. 重新安装依赖

   gem install bundler
   bundle install
   gem install cocoapods
   

5. 若仍有问题，重新编译Ruby并指定libffi路径

   rvm get stable
   rvm reinstall 2.7.5 --with-libffi-dir=$(brew --prefix libffi)
