Question

我完成了flutter应用程序，并且想在ios设备中对其进行测试，因此我使用了Mac笔记本电脑，并且完成了所有安装，但是当我执行“ flutter run”命令时，出现了此错误以调试模式在iPhone 11 Pro Max上启动lib / main.dart ...

让您的一天开心，谢谢哥们的帮助...

MacOS catalina在预安装的红宝石和导轨上存在权限问题。

rbenv是最好的版本控制工具。您需要通过使用终端

来安装此工具：

打开终端并输入以下命令：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

然后运行以下命令：

brew install rbenv ruby-build

# Add rbenv to bash so that it loads every time you open a terminal
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.zshrc
source ~/.zshrc

# Install Ruby
rbenv install 2.7.1
rbenv global 2.7.1
ruby -v
now install pods by going to your ios folder in flutter project
cd ios 
pod install

就是这样。
