Answer 1

überprüfen Sie die Benutzer, die Sie bereitstellen als die entsprechenden Berechtigungen hat Edelsteine ​​zu installieren. Um dies zu überprüfen, melden Sie sich bei dem Server als dieser Benutzer an und versuchen Sie, einige Edelsteine ​​von Ihrem Gemfile zu installieren.

Einige Edelsteine ​​können installieren scheitern, wenn sie Systemabhängigkeiten wie openssl fehlen, Libxml usw.
