everyone. I am trying to compile a file in Miktex but it shows this message:

! keyvalue error: "option-unknown"
! Unknown option 'vargreek-shape' for package unicode-math.
! See the keyvalue documentation for further information.
! For immediate help type H <return>.

Can you explain to me what it is and how to fix it? Sorry i am completely new to latex and just found this website.

The error means that you have




when there is no option of that name.

There Is an option listed in the manual (I'll ping the author to get that fixed) but the option was removed at the last release.

  • v0.8d (2017/01/25)

    • vargreek-shape=TeX and vargreek-shape=unicode package options dropped; for consistency and compatibility, \phi and \epsilon should and will now behave the same as in `TeX
