我需要運行一個帶有 gems 和 specs 的 ruby?? 專案。當我輸入 bundle install 我收到：
bash-5.1# bundle install
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and
installing your bundle as root will break this application for all non-root
users on this machine.

我試圖說服他們切換到 Slackware 作為主要作業系統，但我在安裝和運行使用 psql、ruby 的骨架程式時遇到了麻煩，很快就可以在 rails 上使用 ruby??。
I installed libpqxx slackbuild, sqlite3 gem, postgresql (14.2) slackbuild and when I run rnu ./import_db.sh it says: bash-5.1# ./import_db.sh dropdb: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket? createdb: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket? psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory Is the server running locally and accepting connections on that socket? bash-5.1#
uj5u.com熱心網友回復：
我剛剛意識到 Slackwareslackpkg用作包管理器。不太確定這是否是您需要的庫，但嘗試安裝：
slackpkg install libpqxx
