升级MacOS Ventura后Flutter SDK显示0.0.0-unknown问题求助

问题现象 #

升级MacOS Ventura后，打开Flutter项目无法构建，提示当前Flutter SDK版本为0.0.0-unknown，执行flutter pub get时版本解析失败。

具体报错信息 #

执行flutter pub get的报错：

Running "flutter pub get" in elfi_menu...
The current Flutter SDK version is 0.0.0-unknown.

Because country_icons 2.0.2 requires Flutter SDK version >=0.1.4 and no versions of country_icons match >2.0.2 <3.0.0, country_icons ^2.0.2 is forbidden.
So, because elfi_menu depends on country_icons ^2.0.2, version solving failed.
pub get failed (1; So, because elfi_menu depends on country_icons ^2.0.2, version solving failed.)
Exited (1)

后续发现报错上方存在xcrun相关错误：

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

排查尝试 #

• 重装Flutter SDK，问题依旧
• 新建Flutter项目，同样出现该报错
• 网上查询到的解决方案多针对Windows系统，不适用于Mac环境

解决方法 #

在终端执行以下命令，安装缺失的Xcode Command Line Tools：

xcode-select --install
