Xcode 构建失败并且重复需要命令行开发工具安装

Question

I have updated Xcode to Version 13.4.1 (13F100), Then tried to run a flutter project

Launching lib/main.dart on iPhone SE (3rd generation) in debug mode...
Xcode build done.                                            2.9s
Failed to build iOS app
Error output from Xcode build:

with an alert

The "actool" command requires the command line developer tools. Would you like to install the tools now?

And if I run it from Xcode it gives me this error:

This repetitively occurs even if I press the "Install" button.

Answer 1

Same issue here, but with git instead of actool . Another coworker just also got this but with clang ... what is going on over at apple?

What just fixed mine was actually opening up xcode and having it run its installer there instead of allowing the automatic pop-up to continue to "install" and then ask again in a few minutes.
