Re: Problems using luarocks

[meino.cramer@...]

Hi Hisham,

thank you for your help! :)

In the meanwhile, I got this:

solfire:/home/user>eval `luarocks path`
zsh: no matches found: LUA_PATH='/usr/lib64/lua/luarocks/share/lua/5.1//?.lua;/usr/lib64/lua/luarocks/share/lua/5.1//?/init.lua;/usr/share/lua/5.1//?.lua;/usr/share/lua/5.1//?/init.lua;/usr/lib64/lua/luarocks/share/lua/5.1//?.lua;/usr/lib64/lua/luarocks/share/lua/5.1//?/init.lua;/usr/share/lua/5.1//?.lua;/usr/share/lua/5.1//?/init.lua;./?.lua;/usr/local/share/lua/5.1/?.lua;/usr/local/share/lua/5.1/?/init.lua;/usr/local/lib/lua/5.1/?.lua;/usr/local/lib/lua/5.1/?/init.lua;/usr/share/lua/5.1/?.lua;/usr/share/lua/5.1/?/init.lua'

stack traceback:

What can I do to make it work?

Thank you very much in advance for any help!
Best regards,
