ios - Pod Install : Ignoring ffi-1. 13.1 因为它的扩展没有被构建。试试 : gem pristine ffi --version 1. 13.1

Question

我试过运行 pod install在我的 Xcode 项目中，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

当我跑 gem env ， 我有

    RubyGems Environment:
  - RUBYGEMS VERSION: 3.0.3
  - RUBY VERSION: 2.6.3 (2019-04-16 patchlevel 62) [universal.x86_64-darwin20]

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。不确定其他人都有这个问题。

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
