cant' resolve object-assign

웹 게임을 만들며 배우는 React

2-5를 따라 구현하다가 npx webpack을 실행하면 다음과 같은 에러가 발생합니다. ERROR in ./node_modules/react-dom/cjs/react-dom.development.js Module not found: Error: Can't resolve 'object-assign' in 'S:\study\react-webgame\lecture\node_modules\react-dom\cjs' @ ./node_modules/react-dom/cjs/react-dom.development.js 17:14-38 @ ./node_modules/react-dom/index.js @ ./client.jsx @ multi ./client ERROR in ./node_modules/react/cjs/react.development.js Module not found: Error: Can't resolve 'object-assign' in 'S:\study\react-webgame\lecture\node_modules\react\cjs' @ ./node_modules/react/cjs/react.development.js 16:14-38 @ ./node_modules/react/index.js @ ./client.jsx @ multi ./client ERROR in ./node_modules/react-dom/cjs/react-dom.development.js Module not found: Error: Can't resolve 'scheduler/tracing' in 'S:\study\react-webgame\lecture\node_modules\react-dom\cjs' @ ./node_modules/react-dom/cjs/react-dom.development.js 19:14-42 @ ./node_modules/react-dom/index.js @ ./client.jsx @ multi ./client 그래서 object-assign을 설치해봐도 에러는 같습니다.

스프링 MVC 2편 - 백엔드 웹 개발 활용 기술

안녕하세요 강사님, 정말 좋은강의 항상 잘 듣고 있습니다. 저가 BindingResult에 관련해서 따로 실습을 진행하다가, html에 에러가 출력되지 않아 애를먹고있어 부득이하게 질문을 올리게 돼었습니다 .. ㅠㅠ 컨트롤러에 BindingResult를 log에 출력해봐도 정상적으로 출력되고, 리다이렉션도 되는것을 보면 컨트롤러부분은 아닌것 같고, 타임리프쪽의 문제인것 같은데 도저히 해결방법을 모르겠어서 질문드립니다.. ... 강의 항상 잘 듣고 배우고있습니다. 감사합니다 순서대로 컨트롤러, messeage.properties, html입니다. @PostMapping public String joinUser(userInfo userinfo, mangerInfo mangerinfo, BindingResult bindingResult, RedirectAttributes redirectAttributes,Model model){ log.info("userinfo.getId()={}",userinfo.getId()); log.info("userinfo.getPassword()={}",userinfo.getPassword()); log.info("userinfo.getEmail()={}",userinfo.getEmail()); if(userinfo.getId().isEmpty()){ bindingResult.addError(new FieldError("userinfo", "id", userinfo.getId(), false, new String[]{"login.id"}, null, null)); } if(userinfo.getPassword()==null){ bindingResult.addError(new FieldError("userinfo","password",userinfo.getPassword(),false,new String[]{"login.password"},new Object[]{45},null)); } if(userinfo.getEmail().isEmpty()){ bindingResult.addError(new FieldError("userinfo","email",userinfo.getEmail(),false,new String[]{"login.email"},null,null)); } if(bindingResult.hasErrors()){ model.addAttribute("errors",bindingResult); log.info("errors={}",bindingResult); return "Join/signUp"; }else { if (mangerinfo.getNumber() == null) { joinService.join(userinfo.getEmail(), userinfo.getId(), userinfo.getPassword(), null); userInfo joinResult = joinService.myInfo(userinfo.getId()); redirectAttributes.addAttribute("id", joinResult.getId()); redirectAttributes.addAttribute("email", joinResult.getEmail()); } else { joinService.join(userinfo.getEmail(), userinfo.getId(), userinfo.getPassword(), mangerinfo.getNumber()); userInfo mangerInfo = joinService.myInfo(userinfo.getId()); redirectAttributes.addAttribute("id", mangerInfo.getId()); redirectAttributes.addAttribute("email", mangerInfo.getId()); } return "redirect:/Join/{id}"; } } login.id=id는 필수로 작성해야 합니다. login.password=비밀번호는 필수로 작성해야 합니다. 또한 최대길이는 {0} 입니다. login.email=이메일은 필수로 작성해야 합니다. <!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>sign up</title> <link rel="stylesheet" href="/css/signUp.css"> <link rel="stylesheet" th:href="@{/css/signUp.css}"> <style> .field-error { border-color: #dc3545; color: #dc3545; } </style> </head> <body> <form th:action th:object="${userInfo}" method="post" name="form"> <div id="join"> <h1>회원가입</h1> <table> <tr> <td>ID</td> <td> <label> <input type="text" th:name="id" th:field="*{id}" th:errorclass="field-error"> <div class="field-error" th:field="*{id}" th:if="${#fields.hasErrors('id')}" th:errors="*{id}"> id 오류 </div> </label> </td> </tr> <tr> <td>비밀번호</td> <td> <label> <input type="password" th:name="password" th:field="*{password}" th:errorclass="field-error"> <div class="field-error" th:errors="*{password}" > password 오류 </div> </label> </td> </tr> <tr> <td>비밀번호 확인</td> <td><label> <input type="password" th:field="*{password}"> </label></td> </tr> <tr> <td>관리자입니까?</td> <td> <label> <input type="checkbox" name="checkbutton" onclick="f_check()"> </label> </td> </tr> <tr> <td>관리자 번호</td> <td> <label> <input type="text" name="textbox"> </label> </td> </tr> <tr> <td>e-mail</td> <td> <label> <input type="text" name="email" th:field="*{email}" th:errorclass="field-error"> <div class="field-error" th:errors="*{email}" > email 오류 </div> </label> </td> </tr> <tr> <td>e-mail 인증번호</td> <td><label> <input type="text" name="emailCheck" > </label></td> </tr> <tr> <td colspan="2" class="answer"> <input type="button" value="나가기"> <input type="submit" value="가입하기"> </td> </tr> </table> <script src="../js/signUp.js" charset="utf-8"></script> </div> </form> </body> </html>

스스로 구축하는 AWS 클라우드 인프라 - 기본편

안녕하세요! 강의 잘 듣고 있습니다. 앞선 구조 강의에서 그림상 RDS를 10.0.5.0/24 subnet에 배치시키고 있는데 현재 강의 상에서는 rds를 해당 subnet으로 배치시키는 과정이 없는것 같습니다. 생성한 RDS를 확인해보니 서브넷 ID로 할당된 것은 확인할 수 없고 서브넷 그룹과 서브넷 그룹에 포함된 서브넷만 보여주는 것을 확인했습니다. 결론은 RDS는 앞선 구조 강의 그림처럼 서브넷 ID 10.0.5.0으로 할당이 불가능하고 통신이 가능한 서브넷 그룹을 선택하는것인 것 같은데 제가 이해한게 맞나요?

안녕하세요 제로초님. 다름이 아니라 3장 마지막 부분 캐루셀 구현하기를 들으면서 적용을 해봤더니 위와같이 슬라이더창이 생깁니다. 전체화면이 채워지는게 아니라 레이아웃이 있던 만큼의 화면에만 사진이 꽉찹니다. 에러메세지가 뜨는것도 아니라 초심자 입장에서는 디버깅을 하기가 조금 어렵습니다. 혹시 의심가시는 부분이 있으실까요? 혹시나 답변하시는데 조금 편해지실까 싶어 제가 지금까지 작성한 코드 깃헙 링크도 같이 첨부하겠습니다..
