MySQL Workbench：“运行时错误：无法执行命令 chcp”

问题描述 投票：0回答：1

我有一个使用 MySQL 的工作应用程序。然后，出于内存原因，我卸载了 Workbench（以及我认为与 MySQL 相关的所有内容），几个月后再次安装它，然后打开它。我没想到会看到当时的联系（我以为我卸载并删除了所有内容），但它们就在那里。当我现在双击任何这些连接（包括根连接）时，我收到一条错误消息：

无法获取管理访问权限

运行时错误：无法执行命令 chcp。请确保 C:\Windows\System32 目录位于您的 PATH 环境变量中

我不明白整个“路径变量”的概念，但似乎我有那条线

当我点击这个

我明白了

我尝试再次将 

C:\Windows\System32
添加到该列表中，但没有帮助，我收到相同的错误消息

当我关闭原来的错误消息时，会弹出新的错误消息

未处理的异常：当前配置文件未启用 WMI

查看日志了解更多详情

我检查了日志，但我发现它没有太大帮助。如果不介意的话我就复制全文

“Python 代码中未处理的异常”对我来说非常困惑，因为我用 Java 编写代码。我不知道 Python 与什么有什么关系

一些建议（包括在StackOverflow）该消息可能与系统区域设置有关，但我不认为更改系统区域设置是可接受的解决方案（此外，在我卸载它之前它工作得很好，所以它一定是错误的处理方式）

“哦，愚蠢的我，我只是忘了安装 MySQL 服务器本身，”我想。我访问了此页面，下载了安装程序，选择了 MySQL Server（以及连接器 J，以防万一，尽管我的想法是只需将其添加为 Java 项目中的 Maven 依赖项）并启动该过程。在MySQL服务器配置阶段，弹出了这个

System.NullReferenceException：Ссылка на объект не указывает на экземпляр объекта。 MySql.Installer.Plugins.Server.ServerConfigurationController.ValidateServerFilesHaveRecommendedPermissions() MySql.Installer.Plugins.Server.ServerConfigurationController.SetPages() в MySql.Installer.Wizards.ConfigWizard.ConfigWizard.ShowWizard(Package包、MainFormparentMainForm、ConfigurationType配置类型)

我按了“Продолжить”（意思是“继续”），然后按“完成”，但安装显然没有正确完成。当我在安装程序中单击“重新配置”时，会出现相同的错误。不用说，Workbench 仍然无法正常工作

当我第一次安装MySQL时，我从未配置过任何PATH变量，也没有任何异常

我的笔记本电脑操作系统是 Windows 10, x64

让 MySQL 重新启动并运行对我来说至关重要，因为我需要能够很快在视频通话的技术面试中展示该应用程序

我应该怎样做才能确保它？

你几乎做到了。事实上，您必须安装 MySQL 服务器。最直接的方法确实是下载安装程序并选择 MySQL Server 进行下载。但！您也犯了下载 Connector J 的错误（事实上，您可能只是在 Java 项目中添加 Maven 依赖项）。现在，分步解决方案是这样的

  1. 打开安装程序，选择服务器和连接器并删除（卸载）它们（您可以保留工作台）
  2. 再次选择MySQL Server并正确安装。它应该没有问题（包括配置）。您可能会看到一些上次（不成功）尝试设置时未看到的额外步骤，例如设置 root 帐户密码
  3. 在 Workbench 的帮助下创建数据库以及您的应用程序依赖连接到数据库的用户

现在应该一切正常了！
