无法运行任何 flutter 命令“flutter 工具无法访问文件或目录”

Question

每当我运行 flutter 命令时，包括：

• 扑医生
• 扑干净
• 颤振通道[任何通道]
• ETC

我收到以下错误：

就在我开始收到此错误之前，我执行了以下操作：

• 删除了 Library/developer/coresimulator/caches 文件夹
• 将颤振通道更改为beta

我试图为 xcode 更新获取磁盘空间。

Answer 1

我的问题是从 Windows 导入项目。我将导入的文件夹与在 MacOS 上创建的文件夹进行了比较，区别在于出现了扩展属性。所以我的解决方案是通过命令行删除扩展属性：

$ sudo xattr -c -r  <project_folder> 

Answer 2

当我将 flutter 版本迁移到 2.0 时，我也遇到了同样的问题。唯一的解决方案是向用户授予该位置的权限。

你可以简单地运行这个命令：

$ sudo chown -R <username> /Users/<username>/.config

应替换为您的用户名。

Answer 3

然后转到 flutter sdk 文件夹，在 bin 文件夹中在终端中打开此路径。现在运行命令“git stash”

现在执行您的命令“flutter channel beta”
