Thanks for the guidance, I finally get my Lucida Math work. After the \showfont step, I found that I didn't have the "tex-ma" vector font, and the last two lines in math-vfu.lua should be changed to: { name = "hlcra.tfm", vector = "tex-mb" }, { name = "hlcrm.tfm", vector = "tex-mi" }, in my case.
By the way, there's a typo in fonts.enc.math["tex-mi"] in math-vfu.lua, the comment "righttharpoonup" has an extra "t" and I just wish it could be perfect.
