# We need to load all external packages first
# Reference: https://meta.discourse.org/t/plugin-using-own-gem/50007/4
# After testing, we determined that we do not need to load all the dependent packages already installed in the Discourse core. However, `ffi` is required because we encountered the error: `Error installing llhttp-ffi Gem::MissingSpecError: Could not find 'ffi' (>= 1.15.5)`.
