我使用react-native init创建一个应用程序，然后在iOS文件夹中运行pod install。但是，出现以下错误：
/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require': dlopen(/Library/Ruby/Gems/2.6.0/gems/ffi-1.13.1/lib/ffi_c.bundle, 0x0009): dependent dylib '@rpath/libffi.6.dylib' not found for '/Library/Ruby/Gems/2.6.0/gems/ffi-1.13.1/lib/ffi_c.bundle'. relative file paths not allowed '@rpath/libffi.6.dylib' - /Library/Ruby/Gems/2.6.0/gems/ffi-1.13.1/lib/ffi_c.bundle (LoadError)
我跑了brew install libffi和brew upgrade libffi并重试了。结果相同。
运行的pod --version给出：
sh-3.2# pod --version

对我有用的东西：gem install ffi
我遇到了上面的错误，发现this post暗示它可能与ffi gem的特定版本有关。更新gem可以解决错误，并允许我pod install。
答案 1 :(得分：0)
对于我对pod的实验，请确保您使用的是ruby 2.2.2。 我看到您的ruby版本是2.6.0，请添加rbenv或rvm来控制您的ruby版本。
再次，确保当前文件夹使用的是ruby 2.2.2。
