※ 引述《hau (小豪)》之铭言： : 我用 : \usepackage{fancyhdr} : \pagestyle{fancy} : 它会出现没发现 fancyhdr.sty ，然后要我安装。 : 我就点安装。 : 最后还是出现下面的错误讯息 : ! LaTeX Error: File `fancyhdr.sty' not found. : Type X to quit or <RETURN> to proceed, : or enter new name. (Default extension: sty) : 我重编译，还是一样要我安装 fancyhdr.sty。看起来像是安装失败。 : 可是我不会手动安装，不知是哪出了问题？？ 我到 MiKTex Console 去看发现更新的地方有错误。 后来我直接移除 MiKTex，并重新安装basic-miktex-22.10-x64.exe 安装完后，自动更新还是有问题，我到 MiKTex Console 去看。 更新错误的详细说明是： SetupVersion: 22.10 Configuration: Regular GitInfo: f9aad01 / 2022-10-15 09:37:00 OS: Windows 10.0.19045 SharedSetup: no LinkTargetDirectory: C:\Users\admin\AppData\Local\Programs\MiKTeX\miktex\bin\x64 PathOkay: yes LastUpdateCheck: not yet LastUpdate: not yet LastUpdateDb: not yet SystemAdmin: yes RootPrivileges: no AdminMode: no Root0: C:\Users\admin\AppData\Roaming\MiKTeX Root1: C:\Users\admin\AppData\Local\MiKTeX Root2: C:\Users\admin\AppData\Local\Programs\MiKTeX UserInstall: C:\Users\admin\AppData\Local\Programs\MiKTeX UserConfig: C:\Users\admin\AppData\Roaming\MiKTeX UserData: C:\Users\admin\AppData\Local\MiKTeX Invokers: non-existing/explorer The following issues were detected: 1: major issue: So far, you have not checked for MiKTeX updates.
