VS Code运行React项目报错ERR_PACKAGE_PATH_NOT_EXPORTED求助

执行npm start后出现如下错误：

PS C:\Users\gaveshanapraveen\Downloads\react-based-online-escape-game-main\react-based-online-escape-game-main> npm start

> digital-event-2021-main-app@0.1.0 start

  code: 'ERR_PACKAGE_PATH_NOT_EXPORTED'
}

Node.js v18.14.0

解决方法 #

• 降级Node.js版本
  Node.js 18对ES模块导出校验严格，切换到16.x LTS版本兼容性更好，用nvm操作：

  nvm install 16
  nvm use 16
  

  之后重新执行npm install和npm start。

• 升级相关依赖
  更新postcss-safe-parser到兼容版本：

  npm uninstall postcss-safe-parser
  npm install postcss-safe-parser@latest
  

  也可以直接更新所有依赖：

  npm update
  

• 临时修改postcss配置
  找到node_modules/postcss/package.json，在exports字段中添加：

  "./lib/tokenize": "./lib/tokenize.js"
  

  注意：该修改会在下次npm install后被覆盖，仅作临时验证用。

• 清除缓存重装依赖

  npm cache clean --force
  # Windows用户执行：
  # rd /s /q node_modules
  # del package-lock.json
  # Mac/Linux用户执行：
  rm -rf node_modules package-lock.json
  npm install
  npm start
