[React] create-react-app 에러 대응 방법

React 앱을 처음 만들 때 create-react-app 을 사용한다.

npx create-react-app my-app

 

아래와 같은 에러가 발생할 수 있다. 

npm ERR! code ERR_SSL_CIPHER_OPERATION_FAILED
npm ERR! errno ERR_SSL_CIPHER_OPERATION_FAILED
npm ERR! Invalid response body while trying to fetch https://registry.npmjs.org/strip-json-comments: 70080000:error:1C800066:Provider routines:ossl_gcm_stream_update:cipher operation failed:c:\ws\deps\openssl\openssl\providers\implementations\ciphers\ciphercommon_gcm.c:325:
npm ERR!

npm ERR! A complete log of this run can be found in: C:\Users\asoe72\AppData\Local\npm-cache\_logs\2025-02-26T11_27_28_293Z-debug-0.log

npm install --no-audit --save @testing-library/jest-dom@^5.14.1 @testing-library/react@^12.0.0 @testing-library/user-event@^13.2.1 web-vitals@^2.1.0 failed

 

대처방법:

npm config set legacy-peer-deps true

 

설명:

The --legacy-peer-deps flag was introduced with v7 as a way to bypass peerDependency auto-installation; it tells NPM to ignore peer dependencies and proceed with the installation anyway. This is how things used to be with NPM v4 through v6.
