Why have I errors when installing from Luarocks?

I am the developer of this small library: https://github.com/martin-damien/babel and I have a problem with Luarocks releases.

From source

When I install from source with Luarocks I have no problem:

$ luarocks make --local rockspecs/babel-1.2-2.rockspec

From internet

But when deployed (using: tag master, add new rockspec release and publish to Luarocks), I can't install using

$ luarocks install --local babel

Because I encounter the following error:

Installing https://luarocks.org/babel-1.2-2.src.rock... Using https://luarocks.org/babel-1.2-2.src.rock... switching to 'build' > mode stat: malsukcesis eltrovi statinformon pri «locales/zh-HK.lua»: No such > file or directory

Error: Build error: Failed installing locales/zh-HK.lua in /home/damien/.luarocks/lib/luarocks/rocks/babel/1.2-2/lua/locales/zh-HK.lua: locales/zh-HK.lua: No such file or directory

As you can see in https://github.com/martin-damien/babel/issues/14 the error occure on different files (but until now, only with locale files, not with the babel.lua file).

I have no idea why it randomly crash like this, so if someone know why or have an idea from where it could come from...

Thanks in advance,

Damien

The location of the files in the build.modules table is (from the docs on the rockspec format):

relative to source.dir

Where source.dir is

source.dir (string) - the name of the directory created when the source archive is unpacked. Can be omitted if it can be inferred from the source.file field. Example: "luasocket-2.0.1"

and source.file is

source.file (string) - the filename of the source archive. Can be omitted if it can be inferred from the source.url field. Example: "luasocket-2.0.1.tar.gz"

You don't specify source.dir or source.file in your rockspec but you do set source.url (because you have to).

So you have source.url = https://github.com/martin-damien/babel/archive/v1.2-2.zip which (presumably) ends up with source.file = v1.2-2.zip and then source.dir = v1.2-2 but your zip file extracts into a babel-1.2 so luarocks can't find your source files. (The screenshot in the linked issue seems to indicate that luarocks uses source.file = v1.2.zip and the archive extracts to babel-1.2 but I'm not sure how that's possible.)

Add dir = "babel-1.2" to your rockspec's source table an I expect it will work.
