我無法安裝語言包，也不明白這是什麼原因
Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires csineneo/lang-traditional-chinese ^1.13 -> satisfiable by csineneo/lang-traditional-chinese[1.13.1].
- csineneo/lang-traditional-chinese 1.13.1 requires flarum/core ^0.1.0-beta.13 -> found flarum/core[v0.1.0-beta.13, ..., v0.1.0-beta.16] but it does not match your minimum-stability.
Installation failed, reverting ./composer.json to its original content.
