便携式 texlive 2019 无法正常工作：fmtutil 错误

我在 Win10 中安装了便携式 texlive 2019，并将 bin\win32 添加到系统 $PATH 变量中。Cmd 命令tex --version给出

TeX 3.14159265 (TeX Live 2019/W32TeX)

但latex sample2e.tex让我陷入

This is pdfTeX, Version 3.14159265-2.6-1.40.20 (TeX Live 2019/W32TeX) (preloaded format=latex)
restricted \write18 enabled.

kpathsea: Running mktexfmt latex.fmt

The command name is D:\Program Files\texlive\2019\bin\win32\mktexfmt
Running the command D:\Program Files\texlive\2019\bin\win32\fmtutil-user.exe
fmtutil [ERROR]: -user mode but path setup is -sys type, bailing out.
D:\Program Files\texlive\2019\bin\win32\runscript.tlu:907: command failed with exit code 1:
perl.exe "d:\Program Files\texlive\2019\texmf-dist\scripts\texlive\fmtutil.pl"  --user --byfmt latex
I can't find the format file `latex.fmt'!

任何帮助都将受到赞赏。

解决方法：

  1. Administrator:Windows Powershell从打开cmd。

  2. 输入命令：

    PS C:\WINDOWS\system32>D:\texlive2019\2019\bin\win32\fmtutil-sys.exe --all

  3. 从 Windows 10 复制C:\VTRoot\HarddiskVolume2\texlive2019\2019\texmf-var\web2c到D:\texlive2019\2019\texmf-var\web2c。

  4. 运行.tex源文件，应该没问题。
