flutter 工具无法访问文件

Question

我尝试运行 Flutter 项目但出现错误

Flutter failed to write to a file at
"C:\Users\Dell\flutter-development\projects\flutter_complete_guide\ios\Runner\GeneratedPluginRegistrant.h". The flutter
tool cannot access the file.
Please ensure that the SDK and/or project is installed in a location that has read/write permissions for the current
user.

版本：

颤振 1.22.4，

视窗 10

我试图用 cmd 和 android-studio 创建一个 Flutter 项目，但结果是一样的。

我还为 flutter-sdk 目录、flutter 项目及其子目录授予了所有（包括 Dell 用户）的完全权限。

一旦尝试使用flutter create myapp从头开始构建项目，则会出现 下一个错误

PS C:\src1\project> flutter create myapp
Recreating project myapp...
  myapp\android\app\src\main\res\mipmap-mdpi\ic_launcher.png (created)
Failed to send crash report due to a network error: SocketException: OS Error: Access is denied.
, errno = 5, address = clients2.google.com, port = 63568
Oops; flutter has exited unexpectedly: "FileSystemException: Cannot copy file to 'C:\src1\project\myapp\android\app\src\main\res\mipmap-mdpi\ic_launcher.png', path =
'C:\src1\flutter\packages\flutter_tools\templates\app\android.tmpl\app\src\main\res\mipmap-mdpi\ic_launcher.png' (OS Error: Access is denied.
, errno = 5)".

确保您拥有 flutter 安装文件夹的所有权。看一下这个。

出现此问题的原因是权限不可用。\n如果您不\xe2\x80\x99\n管理员权限或您的帐户不是管理员\n帐户，Windows 10 将阻止您安装。

获得计算机上帐户的管理员权限可以解决此问题。
