What is the value of metal_dir and do you actually have a package there?

6

no I just copy the jl file and toml file

7

From your error message it looks like the value of metal_dir is "/Users" (and it doesn’t find a Project.toml there). Is that what you intend it to be?

8

ok i understand this metal_dir is outer dir so there is no toml
thats why i directly git clone code can run
thank you so much !
