lua Track: 'busted' command not found.

[aule555]

Hi everyone, i'm not easy with Lua but i've tried to run this command in my terminal like it's simply described in the readme exercice. I've searched for an anwser but i've found anything. Someone have an idea ?
Regards.

Check the INSTALLATION document for the Lua track: https://github.com/exercism/lua/blob/master/docs/INSTALLATION.md

What should be checked for? What problem are you seeing?

@glennj i've tried to reinstall all for busted and i have this error during the installation:

busted 2.0.0-1 depends on luafilesystem >= 1.5.0 (not installed)

@rpottsoh i'm on the second exercice from the lua track, "Hamming", and i just want test my exercice before to send it. The README just say "To run the tests, run the command busted from within the exercise directory." But it seems like there is no busted command, even in the exercice folder.

i've tried to reinstall all for busted and i have this error during the installation:

So then install its dependencies. From the error message it seems as if it were missing the lua development headers. Since you haven't told us which operating system you are using, we can't really tell you the name of the package or from where you could install it.

For ubuntu based systems its probably liblua5.3-dev you are missing, thats explicitely mentioned on the install page linked.

If you are on a different linux please tell us and we'll help you find the correct package.

[aule555]

Nevermind, i'm on Bunsenlabs (debian 9 - based)

[NobbZ]

I am not used to debian based systems, but as far as I remember, they have similar naming conventions as ubuntu.

So libluaX.Y-dev (where X.Y is the version of the lua you installed) should work.

[aule555]

I have already installed lua5.3 and it's apparently the appropriate version. I've got the same problem.

[glennj]

Have you installed liblua5.3-dev? Please follow the given instructions:

$ sudo apt-get install lua5.3 liblua5.3-dev luarocks
$ luarocks install busted

[aule555]

yes i've done it and i have this error during busted installation.

[glennj]

OK, looks like the header files aren't getting installed. What happens when you do this?

$ sudo apt-get install liblua5.3-dev

[aule555]

$ sudo apt-get install liblua5.3-dev

Lecture des listes de paquets... Fait

liblua5.3-dev is already the newest version (5.3.3-1).

I know there is french but i see any error message. Should i try to uninstall / re-install ?

[glennj]

I notice that the error message for building luafilesystem includes this:

gcc -O2 -fPIC -I/usr/include/lua5.2 -c src/lfs.c -o src/lfs.o

So I wonder why it found /usr/includer/lua5.2 when you're talking about having installed lua5.3

[aule555]

should i try an apt-get autoremove lua lua5.3-dev and re-install packages after ?

[glennj]

I'd try to figure out how the luafilesystem build decided lua5.2 should be in the include path.

Also, what's in $HOME/.luarocks? What's in /usr/local/etc/luarocks? /usr/local/lib/luarocks?

What do you see with type -a luarocks?

[aule555]

$ ls $HOME/.luarocks
ls: cannot access '/home/$USER/.luarocks': No such file or directory

anything found.

$ ls /usr/local/etc/luarocks
ls: cannot access '/usr/local/etc/luarocks': No such file or directory

same.

$ ls /usr/local/lib/luarocks
rocks
$ ls -a /usr/local/lib/luarocks/rocks
.  ..  index.html  lua_cliargs  manifest  manifest-5.1  manifest-5.2  manifest-5.3

$ type -a luarocks
luarocks is /usr/bin/luarocks

[NobbZ]

Can you please prefix all commands with LANG=C to see their unlocalized output? Its hard for us to follow the french output…

[aule555]

Nevermind.. i've edited my previous message !

@aule555: Have you found a solution to your problem?

[aule555]

Unfortunately no, i'm still searching.

[NobbZ]

Please remove all lua related packages from you system and then install only the 5.3 packages.

[aule555]

Hi, i have noticed 2 things.
During the installation, i have this warning:

$- sudo apt install luarocks
...
Making manifest for /usr/local/lib/luarocks/rocks
Warning: This looks like a local rocks tree, but you did not pass --local-tree.
Generating index.html for /usr/local/lib/luarocks/rocks

Futhermore:

$- luarocks
...
CONFIGURATION
	Lua version: 5.3
	Configuration files:
		System: /etc/luarocks/config.lua (ok)
		User  : /home/$USER/.luarocks/config-5.3.lua (not found)

	Rocks trees in use: 
		/home/c1c3r0/.luarocks
		/usr/local

Config file in user is not found. Peharps these can be a hint ?

It seems that @glennj detected a problem that was not replied to:

I notice that the error message for building luafilesystem includes this:

gcc -O2 -fPIC -I/usr/include/lua5.2 -c src/lfs.c -o src/lfs.o

So I wonder why it found /usr/includer/lua5.2 when you're talking about having installed lua5.3

Could it be that you have the non--dev version of lua5.2 and the -dev version of lua5.3, and the luarocks program is conflicted wrt. which version to align with?

In any way, have you considered removing all versions of lua other than the one you intend to work with, remove all cached configuration of lua in e.g. ~/.luarocks and similar, check that you have the file /usr/include/lua5.3/lua.h and installing luarocks refers to that file rather than some other 5.2 file?
