Errno:: EACCES: Разрешение отрицается при установке драгоценных камней через gitlab

Я пытаюсь настроить gitlab и таким образом установить некоторые драгоценные камни из другой учетной записи пользователя, используя sudo, но я постоянно получаю ошибку Permission denied.

sudo -u gitlab -H bundle install --deployment --without development test postgres

sudo -u gitlab -H gem install pygments.rb -v '0.3.2'

# no matter how many times I run this command, I always get the same output

# I've tried to chmod
chmod 777 -R /usr/local/lib/ruby



# then Again
sudo -u gitlab -H bundle install --deployment --without development test postgres
# same result, Errno::EACCES: Permission denied - pygments.rb-0.3.2.gem
