mysql - 重新安装期间无法配置 MySQL

Question

我的Windows 10计算机上的 MySQL 服务突然停止并拒绝重新启动。我尝试了许多不同的选项来修复它，但它们都不起作用，所以我决定卸载 MySQL 并重新安装它。

我在卸载前删除了这些文件夹：

• C:\程序文件\MySQL\
• C:\ProgramData\MySQL\
• C:\Users[用户名]\AppData\Roaming\
• C:\Program 文件 (x86)\MySQL\

在重新安装期间，我注意到 Connector .NET 安装失败。

我不确定这是否是问题发生的原因，但安装程序反复失败了配置的“备份 MySQL 数据库”步骤。每次我运行它时，它都会显示以下错误消息：

我不能跳过配置，因为 MySQL 还没有作为服务出现。

我尝试在 C:\ProgramData\MySQL\MySQL Server 8.0\ 中手动创建一个数据文件夹，但这仍然没有解决问题。谁能告诉我为什么我会收到此错误？
