IRC에서 나에게 귀중한 도움을 준 사람들은 그것이 걸린 곳이 아마도 com.hypirion.io.Pipe.join일 것이라고 건의했다.
또한 제안한 대로 lein run -m clojure.main을 시도하여 REPL을 성공적으로 시작했습니다.

마지막으로 그는 nrepl이 아니라 일반 리플이 유효하다는 것은 플러그인 사용에 관한 운영체제의 안전성에 관한 것이라고 지적했다.

모든 그룹에서 linux 사용자를 실수로 삭제한 것을 기억합니다. jack2의 범음을 설정하기 위해 오디오 그룹에 사용자를 추가하려고 했지만, 휠 그룹에 추가했습니다.Archlinux를 다시 설치하고 다시 시도하겠습니다.
만약 필요하다면, 나는 다른 정보를 제공하고, 그것을 복구하거나 필요한 정보를 제공할 수 있는 모든 방법을 시도할 수 있다.
이 대사들을 읽어 주셔서 감사합니다!

토론 #1

이것은 문제가 될 수 없습니다. 코드는 stdin/-out/-err를 하위 프로세스로 다시 정할 뿐입니다.만약 이것이 문제라면 com.hypirion.io.Pipe.join도 실패할 것이다.
이것은 아마도 인터넷과 관련된 문제일 것이다.만약archlinux를 다시 설치한 후에도 이 문제가 여전히 존재한다면, 나는 당신이 lein run -m clojure.main이 아니라 lein repl :connect nrepl://localhost:$port을 시도해서 이것이localhost와 관련된 이상한 문제가 아니라는 것을 검증하기를 바랍니다.lein repl :connect nrepl://127.0.0.1:$port 감사합니다.

$ lein repl :headless
nREPL server started on port 33751 on host 127.0.0.1 - nrepl://127.0.0.1:33751
$ lein repl :connect nrepl://localhost:33751

이것은 예외를 일으켰다.

토론 #셋

행을 추가하여 이 문제를 해결할 수 있을 것 같습니다.이 줄이 이미 파일에 있다면, 맨 위로 옮기기만 하면 됩니다.127.0.0.1 localhost 항목을 삭제했을 때, 나도 같은 오류가 발생했는데, 그 중 IPv6 항목이 하나밖에 없었다./etc/hosts 내가 이 일을 할 때 이것은 #2000과 관련이 있는 것 같다.건의해 주셔서 감사합니다.
상단에는 127.0.0.1이 있고

이 추가되어 재부팅되어 이제 작동할 수 있습니다.

이것이archlinux,java,clojure 또는leiningen과 관련이 있는지 모르겠습니다.어쩌면 너는 이 문제를 해결할 수 있을지도 모른다.
너는 첫 번째 시도에서 문제점을 발견했어!

토론 #5

#2000 솔루션도 이 문제를 무료로 해결할 수 있다고 생각합니다.나는 이것을 저것으로 합칠 것이다.
