Question

我是react-native的新手，我已经使用以下命令通读了开始和安装cocoapods的文档：

sudo gem install cocoapods

这成功了。我正在使用以下提到的环境：

Mac OS 10.14.6
Xcode 11.3.1
CLT 11.3.1
Ruby 2.6.5
Cocoapods 1.9.3

现在，当我运行命令npx react-native init MyProject时，我得到以下日志：

✔ Downloading template
✔ Copying template
✔ Processing template
✖ Installing CocoaPods dependencies (this may take a few minutes)
✖ Installing CocoaPods dependencies (this may take a few minutes)
error Error: Failed to install CocoaPods dependencies for the iOS project, which is required by this template.
Please try again manually: "cd ./MyProject/ios && pod install".
CocoaPods documentation: https://cocoapods.org/

再次，我从pod install目录中尝试了命令ios，得到了以下错误：

请告诉我，我要去哪里了。

Answer 1

所以我找到了解决方法：

问题是在ruby中的这个glog库（如上面的错误日志中所述）。在互联网上搜索有关问题Symbol not found: _ffi_prep_closure_loc

之所以出现，是因为在MacOS 10.14中，ffi库可能是一个旧库，必须对其进行更新。安装最新的ffi库的命令是

gem inst ffi -- --disable-system-libffi

此命令对我有用。

或者另一个解决方案可能是升级MacOS 10.15（Catalina）
