使用`use`命令更改Flutter版本时出现Flutter FVM错误

flutterdart

我想使用flutter fvm版本管理，但在尝试使用新版本时出现了这个错误。那个配置文件会自动生成吗？如何启用权限？

D:\dev_projects\myapp>fvm list

2.2.3

只需使用 fvm use 2.2.3。 - John Joe

fvm use 旨在用于 Flutter 项目中。看起来您正在从 fvm 安装文件夹中使用它。如果您想要全局使用某个版本的 Flutter 并随时调用它，可以使用 fvm global 2.2.3。 - Martyns
@Martyns，它仍然有相同的错误。你说的从fvm安装文件夹中使用它是什么意思？顺便说一下，我正在myapp flutter项目内使用vscode终端。我更新了问题，包括fvm doctor。 - unice
@unice 对不起，你是对的。我误读了日志。 - Martyns

对我来说，这是因为我复制了一个Flutter项目文件夹。我删除了“.fvm”文件夹并使用“fvm use”命令，它就可以工作了。

根据日志建议，我通过开启开发者模式来解决了这个问题。前往设置，搜索开发者设置并从那里启用它。现在重新启动IDE并重试。

我不知道这是否是正确的方法，但我通过以管理员身份运行vscode来解决了它。
