1、解决方案
更新ruby和cocoapods
在flutter中也有人提出问题，也给出了解决方案Issues
2、Ruby
- 查看当前ruby版本
ruby -v
- 升级ruby环境(升级ruby需要借助rvm,需要先安装rvm)
1. curl -L https://get.rvm.io | bash -s stable
2. source ~/.rvm/scripts/rvm
- 升级rvm使用命令
rvm get stable
- 获取ruby版本列表
rvm list known
结果：
# MRI Rubies
[ruby-]1.8.6[-p420]
[ruby-]1.8.7[-head] # security released on head
[ruby-]1.9.1[-p431]
[ruby-]1.9.2[-p330]
[ruby-]1.9.3[-p551]
[ruby-]2.0.0[-p648]
[ruby-]2.1[.10]
[ruby-]2.2[.10]
[ruby-]2.3[.8]
[ruby-]2.4[.10]
[ruby-]2.5[.8]
[ruby-]2.6[.6]
[ruby-]2.7[.2]
[ruby-]3[.0.0]
ruby-head
此时可以根据自己的需要安装指定版本的ruby。
rvm install 3.0.0
- 如果报错
unknown or unsupported macOS version: :dunno (MacOSVersionError)，执行：
brew update-reset
成功后再执行rvm install 3.0.0
- 查看镜像
gem sources -l
结果
*** CURRENT SOURCES ***
https://gems.ruby-china.com
如果结果不一致，可以更换镜像源
sudo gem update --system
// 删除现有镜像源
gem sources --remove https://rubygems.org/
// 新增新的镜像源
gem sources --add https://gems.ruby-china.com/
3、Cocoapods
- 安装cocoapods
// 10.11以前
sudo gem install cocoapods
// 10.11 之后
sudo gem install -n /usr/local/bin cocoapods

- 如果电脑上存在多个Xcode，会报错误
Building native extensions. This could take a while...
ERROR: Error installing cocoapods:
ERROR: Failed to build gem native extension.
要指定默认的Xcode
// 通过应用程序中选取指定的Xcode拖拽到终端，生成后面的链接
sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
指定完后再继续更新cocoapods
sudo gem install -n /usr/local/bin cocoapods
结语
更新完后，再去build后，重新pod install后真机运行试试。。。
