Why is luarocks saying : Error: unknown option '-e' when...

have you tried running the command with the --verbose option? That might show the culprit.

[HolterPhylo]

thanks, I'll try!

Did in cmd: luarocks --verbose install luacheck>log.txt

Searched log.txt for 'Error:' and also 'unknown', no match!

cmd windows shows:

       [--only-server <server>] [--only-sources <url>]
       [--namespace <namespace>] [--lua-dir <prefix>]

So no extra information in log.txt due to --verbose.  

Any suggestion?  Is that a luarocks or a luacheck problem you think?

[Tieske]

I'd suspect it to be a parameter to call Lua itself.

The Lua executable can be used with -e to execute code before starting, eg.

lua -e "print [[hello-world]]"

Luarocks creates some wrappers that use this -e option iirc. Still seems like a LuaRocks problem to me.

Thanks, I'll check with luarocks people!
