Example doesn't work resty.session.serializers.json

[digitalshamansky]

Hello, tried to test session, tried to install with opm and luarocks see same error, manual placing modules is also didn't help. Don't know what to check else.

session.lua and session dir with modules exists.

nginx http contains path

lua_package_path '/usr/local/openresty/lualib/?.lua;/usr/local/openresty/lualib/resty/session/?.lua;/usr/local/openresty/site/lualib/resty/?.lua;;';

server { listen 8090; location / { access_by_lua_block { local session = require "resty.session".open{ cookie = { domain = "127.0.0.1" } } if session.present then ngx.log(ngx.ERR, "Session -- " .. ngx.encode_base64(session.id)) else session:start() ngx.log(ngx.ERR, "Started -- " .. ngx.encode_base64(session.id)) end } content_by_lua_block { ngx.say "Hello" } } }

Any suggestions?

Finally it's working, solution is : luarocks install lua-cjson
