CocoaPods安装详细

阅读更多关于 CocoaPods安装详细

开始安装 1 安装需要⽤到Ruby，虽然Mac⾃带了Ruby，不过版本有点⽼了，最好更新⼀下 sudo gem update --system 2 接下来输⼊系统密码就可以安装了，输⼊密码时不会显⽰的，输完回车就⾏了 3 因为Ruby的软件源rubygems.org被屏蔽了，所以要更换源 gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/ 4 接下来查看下源路径是否更换了 gem sources -l 5 接下来安装Cocoapods了 sudo gem install cocoapods 6 不过有可能出错(我就是出错了)，出错的话执⾏下⾯的命令 sudo gem install -n /usr/local/bin cocoapods 7 安装cocospod pod setup 下载完就⼤功告成了(没有⽹络问题就可以开始使⽤了). 如果失败继续下⼀种⽅案 8 如果是下⾯的错误，说明⽹络导致下载时间⾮常长，所以，你可以在 sudo gem install -n /usr/local/bin cocoapods 命令后直接执⾏ git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos

Here are CLI records: remote: Command: 'set -o pipefail; curl -L --fail --retry 5 --retry-delay 1 --connect-timeout 3 --max-time 30 https://s3-external-1

Is there a way I could copy-paste the gems from the vendor/gems/ folder into my gem installation directory and

问题 This error message is a well known error message. (see https://bundler.io/blog/2019/01/04/an-update-on-the-bundler-2-release.html for example.)
