在 85 个 gem 中找不到“ffi”（>= 1.3.0）（Gem::MissingSpecError）在 pod 安装上反应本机 IOS

Question

你好，我正在尝试在 mac mini 上运行我的 React Native 应用程序。我可以运行另一个应用程序也可以运行这个应用程序，但是当我pod install在终端中写入时，它会出现此错误。

1: from /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/rubygems/specification.rb:1449:in `block in activate_dependencies'

    /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 85 total gem(s) (Gem::MissingSpecError)
    Checked in 

'GEM_PATH=/Users/xx/.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

我尝试了很多类似的代码

sudo gem pristine --all,  gem pristine --all

sudo gem install -n /usr/local/bin cocoapods -v 1.8.4

delete and ini pod init/ which gave error
brew reinstall cocoapods
\curl -sSL https://get.rvm.io | bash -s stable --ruby

Answer 1

你可以尝试这个命令

sudo gem uninstall -aIx
rm -rf ~/.gem
sudo gem install cocoapods

sudo chown -R $USER ~/Library/Caches/CocoaPods

Answer 2

对我来说，安装新版本的 ruby​​ 解决了这个问题。

curl -L https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm list known
rvm install 2.7.2
sudo gem install cocoapods

Answer 3

同样的问题。只需更新 gem 包管理器就对我有用

gem update

终端将显示正在安装“ffi”
