获取 Cocoapods 安装错误，同时发出命令 "npx react-native init MyProject"

Question

我是新手 react-native 我已经通读了入门文档并使用以下命令安装了 cocoapods：

sudo gem install cocoapods

这是成功的。我正在使用下面提到的环境：

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，我在 ios 目录中尝试了命令 pod install，得到以下错误：

Abort trap: 6

请让我知道哪里出错了。

Answer 1

所以我找到了解决方案：

问题出在 ruby 中的这个 glog 库（如上面的错误日志中所述）。在 Internet 上搜索了有关该问题的信息 Symbol not found: _ffi_prep_closure_loc

出现这种情况是因为在 MacOS 10.14 中，ffi 库可能是旧的，必须更新。安装最新ffi库的命令是

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

这个命令对我有用。

或者另一个解决方案可能是升级 MacOS 10.15(Catalina)
