${FAQ}

Removing ${FAQ} helps, but I really wonder if it is the case :sweat_smile:

try

xmake create test

Here you go

error: cannot open file: xmake.lua, Not access because it is busy

I don't know why. Maybe a file read/write permission issue

xmake cannot write xmake.lua and do replace vars

[thanhnguyen2187]

I see. It seems plausible. Do you mean ${FAQ} of xmake.lua should be replaced when we run xmake create ...

[waruqi]

I see. It seems plausible. Do you mean ${FAQ} of xmake.lua should be replaced when we run xmake create ...

it will create a template xmake.lua file with ${FAQ} string, then it will be replaced in xmake.lua file. but xmake write file failed.

[thanhnguyen2187]

Thanks. I was wondering if this is related to nix and the way xmake is packaged. I made it work by removing ${FAQ} from xmake.lua. Let's close this for now.

xmake v2.9.5 should work https://github.com/NixOS/nixpkgs/issues/314313
