加载

ffi_c

文件似乎存在问题。我不确定是什么原因导致此错误。有人可以帮我解决这个问题，以便我可以成功运行

pod install

吗？

Answer 1

您遇到的错误可能是由于使用

sudo gem install cocoapods

完成的 CocoaPods 安装与系统的 Ruby 环境之间存在冲突。要解决此问题，请按照下列步骤操作：

1. 卸载使用

   gem

   命令安装的 CocoaPods：

   sudo gem uninstall cocoapods
   

2. 使用 Homebrew 安装 CocoaPods：

   brew install cocoapods
   

   这将确保 CocoaPods 是使用 Homebrew 管理的 Ruby 环境安装的，这应该可以解决

   ffi_c

   加载问题。

3. 如果您之前使用 Homebrew 安装了 CocoaPods，而没有卸载

   gem

   版本，您可能仍然会遇到问题。在这种情况下，请先卸载 Homebrew 版本的 CocoaPods：

   brew uninstall cocoapods
   

   然后，使用 Homebrew 重新安装 CocoaPods：

   brew install cocoapods
   

4. 使用 Homebrew 成功安装 CocoaPods 后，导航到终端中的项目目录并运行：

   pod install
   

   现在执行时应该不会出现“LoadError - 无法加载此类文件 - ffi_c”错误。

通过卸载 CocoaPods 的

gem

版本并使用 Homebrew 安装它，您可以确保 CocoaPods 使用正确的 Ruby 环境以及由 Homebrew 管理的依赖项。这应该可以解决

ffi_c

加载问题并允许您成功运行

pod install

。

如果执行这些步骤后您仍然遇到任何问题，请告诉我，我很乐意提供进一步的帮助。
