flutter doctor FileSystemException：无法打开文件，路径='C：\ Program Files \ flutter \ version'（操作系统错误：权限被拒绝，errno = 5）

Question

因此，我最近切换为抖动，并在PC（Windows 10）和笔记本电脑（Ubuntu 18.04）上进行了设置。 我仅在Windows 10上有问题。 一切正常，然后我从假期回来，尝试在Win 10上运行我的项目，但没有成功。 然后我尝试在命令窗口中运行“ flutter doctor”，甚至没有效果。 所以我的问题是：“为什么'颤抖医生'命令不起作用？”

下面是命令窗口和崩溃报告的图片。

命令窗口： C：\ Users \Jänner>颤抖的医生，糟糕；颤抖已意外退出。向Google发送崩溃报告。已发送崩溃报告（报告ID：7e4a9b2ece9168c9）崩溃报告已写入C：\ Users \Jänner\ flutter_03.log;请通过https://github.com/flutter/flutter/issues告诉我们。

扑灭崩溃报告文件： 扑灭报告请在https://github.com/flutter/flutter/issues提交。

命令

似乎在 Flutter 之类的目录中安装 C:\Program Files\ 并不理想，因为它需要提升权限，这会导致一些错误。

它在 documentation 中写为警告。

有关不同 Program Files 语言的参考，您可以查看 this。
