MikTeX 安装失败,错误“不是文件名数据库文件(错误签名)”

MikTeX 安装失败,错误“不是文件名数据库文件(错误签名)”

我在 Windows 10 上运行 MikTeX 2.9,今天以管理员身份更新了我的 MikTeX 软件包,之后又以普通用户身份更新。在上次更新期间,MikTeX 控制台和正在运行的所有其他程序都停止响应,无法再正常工作,因此我不得不按下电源按钮。重新启动后,我无法再编译任何 LaTeX 文档。当我尝试打开 MikTeX 控制台时(无论是设置、更新或软件包模式,无论是管理员还是用户),我都收到错误Not a file name database file (wrong signature)

所以我想卸载并重新安装该程序,但即使在卸载时(无论是卸载 uninstall.exe 还是 Windows 中的控制面板),我还是会遇到同样的错误,甚至无法再卸载它。所以我从程序目录中删除了 MikTeX 文件夹,并使用 CCleaner 清理了我的计算机和注册表。

然后我尝试重新安装 MikTeX。乍一看,这似乎可行,但在安装结束时,MikTeX 再次失败,并出现以下错误:

Not a file name database file (wrong signature).
Info: path="C:\ProgramData\MiKTeX\2.9\miktex/data/le\1756f6ade37d5f870f23c05a7f81e257.fndb"

我尝试为所有用户(管理员模式)和单个用户安装几次,但总是出现相同的错误。我关闭了防病毒程序和防火墙,并在被要求即时安装软件包时选择了“先询问我”。这也没有帮助,仍然是相同的错误。我已经尝试了几个小时,但现在毫无头绪。Windows 昨晚进行了更新。也许这与此有关?

据我所知,安装已基本完成。程序目录中有我卸载前的所有文件夹和 .exe 文件。我不明白为什么它不起作用以及错误意味着什么。这是最后一个 .log 文件:

Sorry, but "MiKTeX Configuration Utility" did not succeed.

You may want to visit the MiKTeX project page, if you need help.

请帮助我让 MikTeX 再次工作。

答案1

我设法解决了这个问题。

解决方案 1: 正如 RobtAll 在上面的评论中指出的那样,MikTeX portable 可以作为一种解决方法。

解决方案 2: 根据 Ulrike Fischer 的建议,我向GitHub MikTeX 问题跟踪器。显然,该错误是由损坏的文件名数据库文件引起的,我被建议删除它们。昨天我完全删除并卸载了 MikTeX,找不到任何剩余的文件。但是,当我fndb在系统上开始搜索时,它实际上在不再存在的目录中找到了五六个 .fndb 文件。由于我file could not be found在尝试删除它们时收到错误消息(),因此我运行 CCleaner 并再次清理了系统(包括注册表)。即使在那里,仍然出现了一些本不应该存在的 MikTeX 文件和路径。之后我重新启动了电脑,从网站下载了基本的 MikTeX 安装程序,并再次安装了 MikTeX(单用户版)。这次它没有任何错误。

我仍然有点困惑,因为我昨天用 CCleaner 清理了几次系统。但是现在基本的 MikTeX 以及更新软件包和编译我的文档又可以正常工作了。所以我断定这是由于这些 .fndb 文件造成的。
