미해결따라하며 배우는 노드, 리액트 시리즈 - 기본 강의
Functions are not valid as a React child. This may happen if you return a Component instead of <Component /> from render. 에러 질문
https://github.com/BomUlUL/NodeReact/commit/dea7495e633062b58f7afe7959c3974fb34a27d6 가장 최근의 커밋입니다. 위 커밋을 완료하고 실행해보니 아래와 같은 에러가 떴습니다.. 이전 커밋까지는 정상적으로 작동했습니다. <Component /> 형식으로 리턴해야 하는데 제가 뭘 잘못 리턴한 것 같은데 찾기 힘드네요.. 혹시 도움 주실 수 있으신가요? 참고로 강의 후반에 나오는 것처럼 return(<SpecificComponent />) 추가해도 계속 에러가 뜹니다..

해결됨웹 게임을 만들며 배우는 React
setTries를 하면 Cannot read properties of undefined (reading 'length') 에러가 뜹니다.
안녕하세요 제로초님. 항상 좋은 강의 감사드립니다. 유튜브로 강의 듣다가 3-8강에서 질문을 하기 위해 인프런 수강신청하여 질문 남깁니다. (유튜브는 질문댓글이 삭제되더라구요) 코드를 아래와 같이 작성하였는데, 리액트가 tries.length를 인식하지 못하는 현상이 발생합니다. tries 자체는 useState로 초기화해주었는데 tries.length의 length를 인식하지 못하는 이유가 무엇인가요? 문제 원인을 찾기 위해 setTries를 onChangeInput에 넣었을 때, 타이핑하자마자 바로 에러가 뜨는 걸로 봐선 tries를 setState할 때 에러가 발생하는 것 같은데 명확한 에러원인을 잘 모르겠습니다. 코드는 아래와 같습니다. https://github.com/kth990303/TH-s-Web/issues/1 https://github.com/kth990303/TH-s-Web/tree/master/react-webgame/baseball import React,{useState} from 'react'; import Try from './Try' const getNumbers=()=>{ const candidate=[1,2,3,4,5,6,7,8,9], ans=[]; for(let i=0;i<4;i++){ const chosen=candidate.splice(Math.floor(Math.random()*(9-i)), 1)[0]; ans.push(chosen); } return ans; } const NumberBaseball=()=>{ const [result, setResult]=useState(''); const [value, setValue]=useState(''); const [answer, setAnswer]=useState(getNumbers()); const [tries, setTries]=useState([]); const onSubmitForm=(e)=>{ e.preventDefault(); if(value===answer.join('')){ setResult('홈런!'); setTries((prevTries)=>{ [...prevTries, {try:value, result:'홈런!'}] }) } else{ const answerArray=value.split('').map((v)=>parseInt(v)); let strike=0, ball=0; if(tries.length>=9){ setResult(`10번 넘게 틀려서 실패! 답은 ${answer.join(',')}였습니다!`); alert('게임을 다시 시작합니다.'); setValue(''); setAnswer(getNumbers()); setTries([]); } else{ for(let i=0;i<4;i++){ if(answerArray[i]===answer[i]){ strike++; } else if(answer.includes(answerArray[i])){ ball++; } } setTries((prevTries)=>{ [...prevTries, {try: value, result:`${strike}스트라이크 ${ball}볼입니다.`}] }) setValue(''); } } } const onChangeInput=(e)=>{ console.log(tries.length); setValue(e.target.value); } return( <> <h1>{result}</h1> <form onSubmit={onSubmitForm}> <input maxLength={4} value={value} onChange={onChangeInput} /> <button>입력!</button> </form> <div>시도: {tries.length}</div> <ul> {tries.map((v,i)=>{ return( <Try key={`${i+1}차 시도: ${v.try}`} tryInfo={v} /> ); })} </ul> </> ) } export default NumberBaseball; 감사합니다!

미해결R과 Python으로 하는 문서자동화 (기초)
R 4.1.0
안녕하세요. 코딩 초보자라 선생님 강의 진행에 맞춰 떠듬적거리며 공부를 하고 있습니다. 초반부터 장애에 부딪쳐 질문 드립니다. 1. 다운로드 하라시던 버젼이 없어 R 4.1.0을 받은 것이 강의와 다른 점입니다. 2. sys.라는 명령어하나를 완성 하지 못할 정도로 글자 하나 쓸 때마다 첨부 화일 1과 같은 에러 표시가 뜹니다. 그래도 에러메시지를 지워가며 명령어를 끝까지 쓰면 원하는 결과가 나오기는 합니다. 3.writeLines 명령어에는 다음과 같은 첨부화일2와 같은 에러 메시지가 뜹니다. environment variables에 강의 내용과 같이 변경사항을 추가 했음을 여러번 확인했습니다. 뭐가 잘못되었을까요?

미해결설계독학맛비's 실전 Verilog HDL Season 1 (Clock부터 Internal Memory까지)
파일설치는 완료됬는데 이후 과정에서 오류가 생깁니다.
안녕하세요. 리눅스 처음 다루는 학생입니다! 동영상(Verilog HDL 0장)대로 해서 설치까지는 완료했는데 그 이후에 실행할 때 오류가 나고 소싱도 안됐습니다. 그래서 동영상에서 하는 것들 여러가지를 해보다가 library link 과정에서 뭘 잘못했는지 libtinfo.so.5 가 빨간색으로 표시되네요ㅠ 어떻게 문제를 해결할까요? 혹시 다시깔 수 있다면 다시깔 수 있는 방법이라도 알려주세요.감사합니다!!

예제파일이 있었으면 좋겠네요. (오타때문인지 에러가 납니다. 못찾겠어요; ㅋㅎ)
- 학습 관련 질문을 남겨주세요. 상세히 작성하면 더 좋아요! - 먼저 유사한 질문이 있었는지 검색해보세요. - 서로 예의를 지키며 존중하는 문화를 만들어가요. - 잠깐! 인프런 서비스 운영 관련 문의는 1:1 문의하기를 이용해주세요.강좌 만들어주셔서 감사합니다..폴더 경로가 약간 달라서, 맞춰서 2.29.0 에서 vscode 에서 shift + cmd + p 블랜더 스타트 누르면되었는데.(register print("연결") 로그가 안떠서).2.83.0 LTS 버전으로 바꾼다음 블랜더 스타트조차 다시 안되네요.blender 에서 f3 눌러서 추가한 random addon 도 안보이고요 -_-;.방법을 잘 머르겠습니다..그래서 예제파일이 있었으면 좋겠습니당 ~*

해결됨스프링 입문 - 코드로 배우는 스프링 부트, 웹 MVC, DB 접근 기술
안녕하세요 강의 내용중 'spring.datasource.driver-class-name=org.h2.Driver' 에 대해 질문 드립니다.
안녕하세요 강의를 수강하고 있는 학생입니다. 수강중에 DB 연결을 위해 application.properties에 아래의 내용을 적었습니다. spring.datasource.driver-class-name=org.h2.Driver spring.datasource.url=jdbc:h2:tcp://localhost/~/test server.port=9090 그런데 해당 내용을 적고 나서 아래와 같은 에러가 나타납니다. Cannot resolve class or package 'h2' Cannot resolve class 'Driver' 스스로 해결해보려고 인터넷에서 서칭을 통해 restart도 시켜보고 선생님이 말씀하신대로 gradle에서 refresh도 실행하였지만 해결되지 않았습니다. 어떻게 해야할까요...?ㅠ 감사합니다.

미해결웹 게임을 만들며 배우는 React
require, import를 왜 한가지로 통일해서 써야하나요?
client.jsx에서는 require를 썼고 야구게임.jsx에서는 import를 썼는데 element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: "object". 에러를 받았습니다. 구글링 해보니 한가지로 통일해야한다고 했는데 왜인가욥?
