flutter 升级 - 无法在“/Users/.../.config/flutter”处创建目录。- Flutter 守护进程已终止

Question

在我的 Mac 上升级 flutter 后，“flutter doctor”命令不起作用，因为“无法在“/Users/Michael/.config/flutter”创建目录。flutter 工具无法访问该文件或目录。”

\n

为什么我收到此消息以及为什么我无法再调试：“Flutter Daemon 已终止。在没有活动设备的情况下无法启动”？

\n

在“flutter Upgrade”之前，“flutter doctor”命令可以工作（带或不带 sudo）：

为什么自“flutter 升级”以来我会遇到这些失败以及为什么我无法再调试：“Flutter 守护进程已终止。没有活动设备就无法启动”？

在终端中运行此命令：

sudo chown mohittanwar /Users/mohittanwar/.config

这解决了我的问题... 注意：使用您自己的系统用户名。
