在 Windows 10 上的 Ubuntu 20.04 终端上，initexmf --register-root=/path 后跟 initexmf --update-fndb 无法注册 bib 文件

Question

我已经在 Windows Subsystem for Linux 2 shell 上安装了适用于 Ubuntu 20.04 的 MikTex：

user@machine:/mnt/c/Users/user/OneDrive/Documents/project$ sudo initexmf --register-root=/mnt/c/Users/user/OneDrive/Documents/texmf
initexmf: security risk: running with elevated privileges
user@machine:/mnt/c/Users/user/OneDrive/Documents/project$ sudo initexmf --update-fndb
initexmf: security risk: running with elevated privileges
user@machine:/mnt/c/Users/user/OneDrive/Documents/project$ ls /mnt/c/Users/user/OneDrive/Documents/texmf/bibtex/bib/
library.bib
user@machine:/mnt/c/Users/user/OneDrive/Documents/project$ biber project-file
