Flutter SDK windows 升级 - 拒绝访问，找不到 Cookies

问题描述

我在 Windows 上，我尝试升级到最新的 Flutter sdk 版本，但下面的错误一直出现。仅供参考，我尝试了在 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在文档中解压缩，因为它具有读/写权限、关闭防火墙、在 PowerShell 中运行 Flutter doctor -v 等。

运行 Flutter doctor -v 后，发生了这种情况

我一直回到这个问题。有什么解决办法吗？

解决方法

它奏效了。仅供参考，我没有删除以前的 SDK，而是将它放在 D:\

这是我的修复：

• 我关闭了防火墙
• 移动到旧的 SDK 文件夹（位于 D:）
• 使用管理员权限在 CMD 中运行文件夹（我使用的是 cmder）
• 将 ENV 中的 Flutter 路径替换为之前 SDK 的路径
• 然后运行：

git clean -xfd
git stash save --keep-index
git stash drop
git pull
flutter doctor -v
