最近我正在部署 Discourse，但是遇到了问题导致无法启动。
错误如下：
FAILED

Pups::ExecError: cd /var/www/discourse && su discourse -c 'bundle install --no-deployment --path vendor/bundle --jobs $(($(nproc) - 1)) --without test development' failed with return #<Process::Status: pid 1193 exit 15>

** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one.
./discourse-doctor may help diagnose the problem.

是的——请至少粘贴 100 行内容。
如果你的服务器在中国，大概率是网络问题。看你的日志应该是卡在下载gem包那里，放心，我也一样，这几天因为各种网络问题无法重构。
可能是因为这几天中国正在高考，网络屏蔽非常严重。建议过了这个时期再试，或者走代理。
