xcode - 无法在终端 macOS 10.15.7 上安装 cocoapods

Question

当我像这样在终端上输入时:

sudo gem install -n /usr/local/bin cocoapods

它向我显示这样的错误:

Building native extensions. This could take a while...

错误:安装 cocoapods 时出错:错误:无法构建 gem native 扩展。

要了解此扩展编译失败的原因，请查看可在此处找到的 mkmf.log:

/Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/ffi-1.13.1/mkmf.log

extconf 失败，退出代码 1

Gem 文件将保留安装在/Library/Ruby/Gems/2.6.0/gems/ffi-1.13.1 中以供检查。结果记录到/Library/Ruby/Gems/2.6.0/extensions/universal-darwin-19/2.6.0/ffi-1.13.1/gem_make.out

之后我试着输入:

pod setup --verbose

它显示这样的错误:

-bash: /usr/local/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory

请帮助我解决这个问题，这样我就可以像升级到 MacOS Catalina 10.15.7 之前一样使用 cocoapods

Answer 1

出现此错误时，我建议使用homebrew 安装 CocoaPods。

如果你还没有，运行:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

然后你可以安装 CocoaPods:

brew install cocoapods
