unknown luaJIT command or jit.* modules not installed

/usr/local/openresty/luajit/bin/luajit-2.1.0-beta2: unknown luaJIT command or jit.* modules not installed

openresty-1.11.2.1 installed
lastest opm installed
then I cp opm/bin/opm /usr/local/openresty/bin
when I set dist.ini down and run opm build
it shows error like this

Looks like your OpenResty installation directory tree is incomplete or corrupted?

[pintsized]

I have the same problem, also with 1.11.2.1.

[jhurst@sl6 lua-resty-http]$ opm build

[pintsized]

Appear to be the -b flag passed to luajit? My OpenResty was configured with the default options.

[agentzh]

@pintsized Could you try running the following commands on your side?

/usr/local/openresty/luajit/bin/luajit-2.1.0-beta2 -bl lib/resty/http.lua /dev/null

/usr/local/openresty/luajit/bin/luajit-2.1.0-beta2 -b lib/resty/http.lua /dev/null

[agentzh]

@lilien1010 @pintsized Please try out the latest opm tool in the code repository. Just added more info to the error message and also switched to luajit -b instead of luajit -bl. Please let me know your output if it still breaks.

[pintsized]

@agentzh For me, using the -b flag at all always shows that error:

[jhurst@sl6 lua-resty-http]$ /usr/local/openresty/luajit/bin/luajit-2.1.0-beta2 -bl lib/resty/http.lua /dev/null
/usr/local/openresty/luajit/bin/luajit-2.1.0-beta2: unknown luaJIT command or jit.* modules not installed

/usr/local/openresty/luajit/bin/luajit-2.1.0-beta2: unknown luaJIT command or jit.* modules not installed

I just tried out the latest version - slightly different output but the same error:

[jhurst@sl6 lua-resty-http]$ opm build
found license: BSD 2-Clause "Simplified" or "FreeBSD" license.
extracted verson number 0.09 from main_module file lib/resty/http.lua.
/usr/local/openresty/luajit/bin/luajit-2.1.0-beta2: unknown luaJIT command or jit.* modules not installed
ERROR: failed to run command     _VERSION = '0.09',

Anything else I can do to help?

[agentzh]

@pintsized Your latest output is very helpful. Please git pull and try out the latest version of opm. Thanks!

[agentzh]

@pintsized BTW, what version of perl are you using? Will you show the output of the command perl -v on your side? Thanks!

[pintsized]

[jhurst@sl6 lua-resty-http]$ perl -v

This is perl, v5.10.1 (*) built for x86_64-linux-thread-multi

[pintsized]

Just pulled - slightly different again:

[jhurst@sl6 lua-resty-http]$ /usr/local/openresty/bin/opm build

[agentzh]

@pintsized Okay, it seems that your LuaJIT in the OpenResty installation tree fails to load the standard LuaJIT module, jit.bcsave. Please try the following command and provide the output:

strace /usr/local/openresty/luajit/bin/luajit-2.1.0-beta2 -b lib/resty/http.lua /dev/null 2>&1|grep -i jit

On my side (Fedora Linux x86_64), the output looks like this, which is the corrected behavior:

execve("/usr/local/openresty/luajit/bin/luajit-2.1.0-beta2", ["/usr/local/openresty/luajit/bin/"..., "-b", "lib/resty/http.lua", "/dev/null"], [/* 70 vars */]) = 0
open("./jit/bcsave.lua", O_RDONLY)      = -1 ENOENT (No such file or directory)
open("/usr/local/openresty/luajit/share/luajit-2.1.0-beta2/jit/bcsave.lua", O_RDONLY) = 3
open("/usr/local/openresty/luajit/share/luajit-2.1.0-beta2/jit/bcsave.lua", O_RDONLY) = 3

Wondering if your OpenResty/LuaJIT installation just does not have the jit/bcsave.lua file or your system account just does not have enough permission to read it.

[agentzh]

@pintsized BTW, what Linux distribution are you in? Will you provide as much details as possible? Thanks!

[pintsized]

[jhurst@sl6 lua-resty-http]$ strace /usr/local/openresty/luajit/bin/luajit-2.1.0-beta2 -b lib/resty/http.lua /dev/null 2>&1|grep -i jit
execve("/usr/local/openresty/luajit/bin/luajit-2.1.0-beta2", ["/usr/local/openresty/luajit/bin/"..., "-b", "lib/resty/http.lua", "/dev/null"], [/* 47 vars */]) = 0
open("/usr/share/lua/5.1/jit/bcsave.lua", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/lua/5.1/jit/bcsave.so", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/lib/lua/5.1/jit.so", O_RDONLY) = -1 ENOENT (No such file or directory)
write(2, "/usr/local/openresty/luajit/bin/"..., 50/usr/local/openresty/luajit/bin/luajit-2.1.0-beta2) = 50
write(2, "unknown luaJIT command or jit.* "..., 53unknown luaJIT command or jit.* modules not installed) = 53

Seems it's looking for it in the wrong place for some reason? /usr/share/lua/5.1/jit doesn't exist. bcsave.lua does exist in the OpenResty installation....

This is a Scientific Linux 6 x86_64 environment. I compiled OpenResty with a plain ./configure; gmake; sudo gmake install.

Could LUA_PATH be relevant at all?

[jhurst@sl6 lua-resty-http]$ echo $LUA_PATH
/usr/share/lua/5.1/?.lua

[agentzh]

Oh yeah, your global LUA_PATH environment setting hides all the standard LuaJIT modules.

[agentzh]

@pintsized I'll explicitly clear any LUA_PATH or LUA_CPATH environments in the opm tool then. Such things are painful to debug.

[pintsized]

@agentzh Ah, yep makes sense!

[agentzh]

Okay, please try the latest opm.

[pintsized]

@agentzh To confirm, I fixed my path and all is now working...

[jhurst@sl6 lua-resty-http]$ echo $LUA_PATH
/usr/share/lua/5.1/?.lua;;
[jhurst@sl6 lua-resty-http]$ opm build
found license: BSD 2-Clause "Simplified" or "FreeBSD" license.

lua-resty-http-0.09/lib/resty/http.lua

Will update and test against both this and the old LUA_PATH for good measure.

[pintsized]

@agentzh Confirmed, it works now regardless of LUA_PATH. Thanks! I'll start uploading some modules tomorrow :)

[agentzh]

@pintsized Cool, thanks for your patience!
