Flutter 应用程序无法与 android 工作室一起运行任何人都可以帮助我吗？

Question

I have a Flutter app and when I try to run it, I see an error. I mention belove but app is running when I use Xcode.

In android studio:

Launching lib/main.dart on iPhone 11 in debug mode...
Running pod install...

CocoaPods' output:

      CDN: trunk Relative path: CocoaPods-version.yml exists! Returning local because checking is only performed in repo update

Error output from CocoaPods:

Answer 1

this error come because cocoapod new version not suport utf-8 and flutter widgets use that so you have to export following lines to your terminal and its work

Export this line and its work

export LC_ALL=en_US.UTF-8

Answer 2

Add the following code in your bash profile if you're using bash.

export LANG=en_US.UTF-8

The bash profile is might be

~/.bash_profile or ~/.bashrc

Also if you're using zsh then the profile name will be.

~/.zshrc
