`Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires flarum-lang/spanish 1.3 -> satisfiable by flarum-lang/spanish[1.3.0, 1.3.1, 1.3.2].
- Root composer.json requires hwi/oauth-bundle 0.6.3 -> satisfiable by hwi/oauth-bundle[0.6.3].
- hwi/oauth-bundle 0.6.3 requires symfony/form 2.8|3.0|4.0 -> satisfiable by symfony/form[v2.8.0, ..., v2.8.52, v3.0.0, ..., v3.4.47, v4.0.0, ..., v4.4.46].
- symfony/form[v4.3.0, ..., v4.4.46] require symfony/event-dispatcher 4.3 -> satisfiable by symfony/event-dispatcher[v4.3.0, ..., v4.4.44].
- symfony/form[v4.0.0, ..., v4.2.12] require symfony/event-dispatcher 3.4|4.0 -> satisfiable by symfony/event-dispatcher[v3.4.0, ..., v3.4.47, v4.0.0, ..., v4.4.44].
- symfony/form[v3.4.0, ..., v3.4.47] require symfony/event-dispatcher 2.8|3.0|4.0 -> satisfiable by symfony/event-dispatcher[v2.8.0, ..., v2.8.52, v3.0.0, ..., v3.4.47, v4.0.0, ..., v4.4.44].
- symfony/form[v3.0.0, ..., v3.3.18] require symfony/event-dispatcher 2.8|3.0 -> satisfiable by symfony/event-dispatcher[v2.8.0, ..., v2.8.52, v3.0.0, ..., v3.4.47].
- symfony/form[v2.8.0, ..., v2.8.52] require symfony/event-dispatcher 2.1|3.0.0 -> satisfiable by symfony/event-dispatcher[v2.1.0, ..., v2.8.52, v3.0.0, ..., v3.0.9].
- You can only install one version of a package, so only one of these can be installed: symfony/event-dispatcher[v2.1.0, ..., v2.8.52, v3.0.0, ..., v3.4.47, v4.0.0, ..., v4.4.44, v5.0.0, ..., v5.4.9, v6.0.0, ..., v6.1.0].
- Conclusion: install symfony/event-dispatcher v5.3.0 (conflict analysis result)
You can also try re-running composer require with an explicit version constraint, e.g. "composer require flarum-lang/spanish:*" to figure out if any version is installable, or "composer require flarum-lang/spanish:2.1" if you knowwhich you need.`
