Summary

Error: /usr/local/share/lua/5.1/kong/cmd/start.lua:23: nginx: [error] init_by_lua error: /usr/local/share/lua/5.1/kong/tools/utils.lua:297: error loading module 'stringy' from file '/usr/local/lib/lua/5.1/stringy.so':
dlopen(/usr/local/lib/lua/5.1/stringy.so, 6): Symbol not found: _fastsearch
Referenced from: /usr/local/lib/lua/5.1/stringy.so
Expected in: flat namespace
in /usr/local/lib/lua/5.1/stringy.so
stack traceback:
[C]: in function 'error'
/usr/local/share/lua/5.1/kong/tools/utils.lua:297: in function 'load_module_if_exists'

Steps To Reproduce

1. Removed Kong 0.8.1
2. Installed Kong 0.9.3 using pkg installer
3. Configured the Postgres config to use the same DB that was used by 0.8.1
4. Run migrations 'kong migrations up'
5. Startup Kong to see the error

The same error is seen even on a fresh install (new DB)

Additional Details & Logs

• Kong version -0.9.3

As a tmp fix, you could run:

$ luarocks remove --force stringy
$ luarocks install stringy 0.2-1

[subnetmarco]

This has also been fixed if you re-downloaded the OSX package.

Yes, I can confirm the same. Thanks!
