Possible Dependency Issues?

[RickCarlino]

I did a fresh install of Lua, Moonscript and Lapis on a new box running Linux and got errors when I first attempted to run 'lua help'. The first errors were fixed by installing lua-cjson and the second was fixed after I installed the lpeg luarock. This is the current error I get:

Interesting. LuaRocks should automatically install (lpeg, cjson, etc.) before installing Lapis via the rockspec. What command did you use to install Lapis?

luacrypo isn't listed as a dependency because it's only required if you try to include the module "lapis.encoding" not within nginx. Lapis doesn't do this normally, I only did this for testing.

From your stacktrace it looks like you are running web.moon file directly. I'm guessing you were trying to start the server? In case you missed it here's the tutorial on starting the server: http://leafo.net/lapis/reference.html#creating-an-application-lapis-command-line-tool

[RickCarlino]

Initially, I did a 'sudo luarocks install --server=http://rocks.moonscript.org/manifests/leafo lapis' and tried to compile the simple 'hello world' off of the site homepage as web.moon, which is when the dependency issues showed up.

I did get it running just now, but only after running these additional commands:
sudo luarocks install xavante
sudo luarocks install luafilesystem

...the moment of glory...

rick@mintbox ~ $ sudo moon web.moon
Xavante started on port(s) 80

I'm loving Lapis so far, thanks for all your hard work in leading this project forward.

[leafo]

The Xavante backend is not documented and most likely broken at this point. I'm going to be removing it. I recommend installing OpenResty and using the command lapis server to start the server: http://leafo.net/lapis/reference.html#creating-an-application-lapis-command-line-tool

[datashaman]

I had to add luacrypto and lua-cjson to the dependencies to get tests running. Now to get the tests passing... :)

[leafo]

I updated the tests to print a pending message when luacrypto is missing (I recommend it though). As for lua-cjson, that is definitely a requirement, it should be installed when you install lapis via the rockspec.

luacrypto fails to compile...

luarocks install luacrypto --local
...
src/lcrypto.c: In function ‘luaopen_crypto’:
src/lcrypto.c:1901:19: error: array type has incomplete element type ‘struct luaL_reg’

Error: Build error: Failed compiling object src/lcrypto.o

[starius]

Try the following command:

$ luarocks install luacrypto 0.3.2-1 --local

See yagop/telegram-bot#241

[mathieujobin]

thanks, but it looks like it could not be found...

bash$ luarocks install luacrypto 0.3.2-1 --local

Error: No results matching query were found.

bash$ luarocks search luacrypto

Rockspecs and source rocks:

I tried the other available version but I am getting same compilation error.

The official rockspec for luacrypto has the following Lua version line:

dependencies = {
        "lua >= 5.1, < 5.3",
}

That is why luarocks doesn't list this version for Lua 5.3.

I have fixed incompatibilities with Lua 5.3 this issue in my fork of luacrypto and uploaded modified rockspec to gist.

The following command installs luacrypto from my fork. It should work for Lua 5.3.

$ luarocks install https://gist.githubusercontent.com/starius/b20d3e63929ae678c857/raw/4b4499f442337b6f577422364358590bd00c9d48/luacrypto-0.3.2-2.rockspec --local

You can use this workaround until this issue is fixed in the upstream.

Thanks very much

Not sure if related, but same error message about missing crypto library that I'm talking about on #560..

[leafo]

@Guard13007 there is no longer a reference to the crypto module in the lapis codebase.

• Are you sure you're using the latest version
• Are you sure the error isn't from another dependency?

If you can give me the stack trace then I can tell you what's going on

[TangentFoxy]

Ah, pgmoon is requiring it?

So is pgmoon failing to request this dependency?

[TangentFoxy]

Note: Forgot to verify lapis version, but it should be latest as it's on a fresh server with fresh luarocks install using sudo luarocks install lapis. I will confirm the version number in a few minutes after fixing a script of my own.

[TangentFoxy]

Lapis version 1.7.0
