Question

我尝试在我的 Xcode 项目中运行 pod install，但出现以下错误

    /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/dependency.rb:311:in `to_specs': Could not find 'ffi' (>= 1.3.0) among 84 total gem(s) (Gem::MissingSpecError)
Checked in 'GEM_PATH=/Users/dylan/.gem/ruby/2.6.0:/Library/Ruby/Gems/2.6.0:/System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/gems/2.6.0', execute `gem env` for more information

当我运行 gem env 时，我得到了

    RubyGems Environment:

之前一切正常，我最近做的一件事是将 Xcode 更新到 12.3 和 Big Sur。不确定其他人是否有此问题。

Answer 1

更新到 Big Sur 后遇到同样的问题

重新安装 cocoapods 对我有用

gem install cocoapods

如果出现以下错误，

您可能需要为 ruby 开发安装单独的包环境，例如 ruby-dev 或 ruby-devel。

安装这个

xcode-select --install

Answer 2

xcode-select --install

这对我有用，在更新您的 pod 之前，请运行上面的行，然后使用您的 pod 更新或安装

Pod 安装：忽略 ffi-1.13.1，因为它的扩展没有构建。尝试： gem pristine ffi --version 1.13.1
