Flutter SDK windows升级-访问被拒绝，找不到Cookie

Question

我在windows上，我试图升级到flutter sdk的最新版本，但下面的错误一直出现。仅供参考，我尝试了我在GitHub上找到的大多数修复程序。我从他们的文档中下载了压缩文件，并将其解压到文档中，因为它具有读/写权限、关闭防火墙、在PowerShell中运行flutter doctor -v等。

在运行flutter doctor -v之后，发生了这种情况

我总是回到这个问题上来。有什么好办法吗？

啊，真灵。仅供参考，我没有删除之前的SDK，而是将其放在D:\

以下是我的解决方案：

• 我关闭了防火墙，并移动到旧的SDK文件夹(位于D:中)
• 使用管理员权限运行CMD中的文件夹(我在ENV中使用flutter路径和以前的SDK
• 的路径，然后运行：
