LuaRocks 3.1.3 Windows Warning: Could not find a Lua 5.3 interpreter in your PATH

[kingoftheconnors]

I installed LuaRocks using install.bat. Whenever I run ANY luarocks command (including help commands) I get this warning:

Warning: Could not find a Lua 5.3 interpreter in your PATH. Modules may not install with the correct configurations. You may want to specify to the path prefix to your build of Lua 5.3 using --lua-dir

Despite that, installing dkjson and using luarocks show dkjson worked fine. From what I've seen, warnings should be heeded, so this warning is giving me the creeps.

And yes, C:\lua\bin is in my PATH variable.

Same issue here.
I use the standalone exe.

Run where lua got the follow:

C:\Users\xpoli\Workspace\.lua\bin\lua.exe

Run tree C:/Users/xpoli/Workspace/.lua /A /F got:

Run luarocks:

Hi,

I get this error on 3.2.1 using the all-in-one executable with my WinLua installer. When I use 3.0.3, I do not see the issue.

C:\Users\russh\git\WinLua-Bin [master ≡]> luarocks

I downloaded and installed 3.0.3 and copied the files into the luarocks installed directory. In the same powershell window, I then ran luarocks and do not get the error:

@RussellHaley does the same issue happen with that 64-bit .exe based off master that I shared in the other issue? (it's http://hisham.hm/luarocks/luarocks-test-windows-64.zip if any one else wants to test too!)

[Zulsorai]

I just tried this out quickly as I have been having similar issues and it seems to persist with the new executable.

me too!
