こんにちは、
現在、MyBB から Discourse へのフォーラム移行を試みていますが、いくつかのトピックを読んだにもかかわらず、まだ成功していません。
最新の試みでこれまでに行ったことは以下の通りです：
- MyBB のデータベース（mybb.sql）をダウンロードし、Discourse サーバーにアップロード
- MySQL で mybb という名前のデータベースを作成し、mybb.sql をインポート
その後、こちら に記載されている手順に従いました：
- cd /var/discourse
- ./launcher enter app
- su - discourse
- gem install mysql2
- cd /var/www/discourse/script/import_scripts
- nano mybb.rb を実行し、mybb の詳細情報を記述
- ruby mybb.rb
しかし、この最後のステップで以下のエラーに遭遇して進めません：
discourse@debian94-app:/var/www/discourse/script/import_scripts$ ruby mybb.rb Traceback (most recent call last): 18: from mybb.rb:4:in `\u003cmain\u003e' 17: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:92:in `require' 16: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:92:in `require' 15: from /var/www/discourse/script/import_scripts/base.rb:16:in `\u003ctop (required)\u003e' 14: from /var/www/discourse/script/import_scripts/base.rb:16:in `require_relative' 13: from /var/www/discourse/config/environment.rb:4:in `\u003ctop (required)\u003e' 12: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:92:in `require' 11: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:92:in `require' 10: from /var/www/discourse/config/application.rb:54:in `\u003ctop (required)\u003e' 9: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.3.1/lib/active_support/dependencies.rb:324:in `require' 8: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.3.1/lib/active_support/dependencies.rb:291:in `load_dependency' 7: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.3.1/lib/active_support/dependencies.rb:324:in `block in require' 6: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:31:in `require' 5: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:22:in `require_with_bootsnap_lfi' 4: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/loaded_features_index.rb:92:in `register' 3: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `block in require_with_bootsnap_lfi' 2: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `require' 1: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/compile_cache/iseq.rb:38:in `load_iseq' /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/compile_cache/iseq.rb:38:in `fetch': Permission denied - bs_fetch:atomic_write_cache_file:open (Errno::EACCES) 19: from mybb.rb:4:in `\u003cmain\u003e' 18: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:92:in `require' 17: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:92:in `require' 16: from /var/www/discourse/script/import_scripts/base.rb:16:in `\u003ctop (required)\u003e' 15: from /var/www/discourse/script/import_scripts/base.rb:16:in `require_relative' 14: from /var/www/discourse/config/environment.rb:4:in `\u003ctop (required)\u003e' 13: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:92:in `require' 12: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:92:in `require' 11: from /var/www/discourse/config/application.rb:54:in `\u003ctop (required)\u003e' 10: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.3.1/lib/active_support/dependencies.rb:324:in `require' 9: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.3.1/lib/active_support/dependencies.rb:291:in `load_dependency' 8: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.3.1/lib/active_support/dependencies.rb:324:in `block in require' 7: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:31:in `require' 6: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:22:in `require_with_bootsnap_lfi' 5: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/loaded_features_index.rb:92:in `register' 4: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `block in require_with_bootsnap_lfi' 3: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `require' 2: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/compile_cache/iseq.rb:34:in `load_iseq' 1: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/compile_cache/iseq.rb:44:in `rescue in load_iseq' /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/bootsnap-1.4.6/lib/bootsnap/compile_cache.rb:29:in **`permission_error': bootsnap doesn't have permission to write cache entries in 'tmp/cache/bootsnap-compile-cache' (or, less likely, doesn't have permission to read '/var/www/discourse/vendor/bundle/ruby/2.6.0/gems/pry-rails-0.3.9/lib/pry-rails.rb') (Bootsnap::CompileCache::PermissionError)**\n```\
すでに以下の試みを行いました：
* ユーザーを root に戻す
* `chmod -R 777 tmp/cache/bootsnap-compile-cache`
* `chmod -R 777 /var/www/discourse/vendor/bundle/ruby/2.6.0/gems`
* その後、su - discourse で discourse ユーザーに戻す
しかし、これでも解決しませんでした。この問題を解決する方法をご存知の方はいらっしゃいますか？
