flutter升级-无法在"/Users/.../.config/flutter“中创建目录。- Flutter Daemon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。”

为什么我会收到这样的消息，为什么我不能再调试了：“Flutter守护进程已经终止。没有活动的设备就无法启动”？

在“颤动升级”之前，“颤动医生”-command可以工作(使用和不使用sudo)：

“”

在"flutter upgrade“之后，由于缺少权限，我收到了以下消息(但我是flutter directories的管理员和所有者)：

当我现在运行"flutter doctor -v“时，我得到了同样的失败"failed to create a directory at "/Users/michael/.config/flutter”。

当我运行"sudo flutter doctor -v“时，我得到：

Woah! You appear to be trying to run flutter as root.
   We strongly recommend running the flutter tool without superuser privileges.

为什么我在"flutter升级“后会遇到这些故障，为什么我不能再调试了：”Flutter守护进程已经终止。没有活动的设备就无法启动“？

Answer 1

在终端中运行以下命令：

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。

Answer 2

我也有同样的问题，但当我执行以下步骤时得到了解决。

sudo flutter downgrade

sudo flutter doctor

sudo flutter upgrade

sudo flutter doctor

当颤动升级完成时，我有错误，但当我运行颤动医生时得到了解决。
