React Native执行pod install遇JSON解析错误，求解决方案

在React Native项目目录执行pod install命令安装CocoaPods依赖时，遇到JSON解析错误，提示无法解析文件/Users/apple/.cocoapods/repos/trunk/Specs/0/b/5/PromisesObjC/2.3.1/PromisesObjC.podspec.json，859位置存在意外令牌。

Podfile内容 #

# If you are using a `react-native-flipper` your iOS build will fail when `NO_FLIPPER=1` is set.
# because `react-native-flipper` depends on (FlipperKit,...) that will be excluded
#
# To fix this you can also exclude `react-native-flipper` using a `react-native.config.js`
# ```js
# module.exports = {
#   dependencies: {
#     ...(process.env.NO_FLIPPER ? { 'react-native-flipper': { platforms: { ios: null } } } : {}),
# ```
flipper_config = ENV['NO_FLIPPER'] == "1" ? FlipperConfiguration.disabled : FlipperConfiguration.enabled

解决方法 #

这种错误通常是CocoaPods仓库缓存的Podspec文件损坏导致的，按以下步骤处理：

方法1：清理损坏的Podspec并更新仓库 #

• 删除损坏的Podspec文件：

  rm /Users/apple/.cocoapods/repos/trunk/Specs/0/b/5/PromisesObjC/2.3.1/PromisesObjC.podspec.json
  

• 更新CocoaPods仓库：

  pod repo update trunk
  

• 回到项目iOS目录重新执行pod install

方法2：彻底清理缓存后重新安装 #

如果方法1无效，尝试完全清理缓存：

• 删除本地CocoaPods trunk仓库：

  rm -rf ~/.cocoapods/repos/trunk
  

• 清理项目的Pods目录和锁文件：

  cd ios && rm -rf Pods Podfile.lock
  

• 重新更新仓库并安装依赖：

  pod repo update trunk
  pod install
  

方法3：指定稳定版本的PromisesObjC #

若上述方法仍有问题，可在Podfile中明确指定一个稳定版本的PromisesObjC，避免拉取损坏的版本：
在target 'my_crm' do代码块内添加：

pod 'PromisesObjC', '2.2.0'

添加后执行pod install
