我尝试启动 couchdb：
asedsami@localhost ~> sudo systemctl start couchdb.service
Job for couchdb.service failed because the control process exited with error code.
See "systemctl status couchdb.service" and "journalctl -xe" for details.
未能启动。
asedsami@localhost ~> couchdb -h
cat: /usr/bin/../releases/start_erl.data: No such file or directory
/usr/bin/couchdb: line 47: /usr/bin/../erts-/bin/erlexec: No such file or directory
然后我尝试获取完整日志：
asedsami@localhost ~> sudo journalctl -u couchdb.service

因此，在 Erlang/OTP 18 中存在被弃用的问题scheduler_bind_type，我不知道如何修复，并且感谢您能够提供的任何帮助。

您可能会通过提交一份文件来获得最佳答案错误报告致 Fedora 软件包的维护者。维护者 Peter Lemenkov 还维护 Fedora 中的 erlang 包，并且应该能够提供见解。
