I can find the file FieldOptions.vue on my ojs files where is the location ?

It depends on your install strategy. Did you use the pre-compiled packages or did you use
git clone ... or git pull ... ?

Probably, the above changes are only deployable for the next few days if you use the codebase via git and recompile javascript via npm run build, as described on GitHub - pkp/ojs: Open Journal Systems
