我尝试从git安装flutter，尝试不同的频道，设置我的路径，下载dart，下载android studio的flutter / dart，但我无法克服此错误。

我不知道是什么原因引起的，但是重新安装Git和sdk可能会解决问题。

该错误是由于飞镖引起的。请尝试以下步骤：
1）在您的终端上运行flutter packages get是个好主意
2）在您的终端上运行flutter upgrade
3）通过运行dart --version
4）通过运行which brew
5）还要检查您是否在开发人员通道上，某些人在开发人员通道上遇到问题。如果您愿意，我建议您切换到母版。
如果您没有安装飞镖，建议您安装飞镖。希望这可以帮助。让我们知道是否可行。
