我正在嘗試使用 json 檔案中列出的確切版本安裝依賴項，但出現以下錯誤：
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! Found: [email protected]
npm ERR! node_modules/webpack
npm ERR! webpack@"^4.35.3" from the root project
npm ERR!
npm ERR! Could not resolve dependency:
npm ERR! peer webpack@"^5.1.0" from [email protected]
npm ERR! node_modules/terser-webpack-plugin
npm ERR! dev terser-webpack-plugin@"^5.1.1" from the root project
npm ERR!
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.由于所需版本的依賴項不是最新的，我將 node.js 從最新版本 16 降級到 14 ，并使用 npm i --leacy-peer-deps 安裝，但錯誤顯示仍然相同，似乎node 或 webpack 的版本仍然與依賴項不兼容（從根專案中找到：[email protected] npm ERR！node_modules/webpack npm ERR！webpack@"^4.35.3"）。
我怎么解決這個問題？
這是json串列：

}uj5u.com熱心網友回復：
嘗試在 npm i 之前使用“npm cache clean -f”洗掉 package-lock.json 并清除 npm 快取。
插入符號 (^) 表示法：它將更新您到所有未來的次要/補丁版本，而不增加主要版本。^2.3.4 將使用從 2.3.4 到 <3.0.0 的版本
波浪號（~）：它將更新您到所有未來的補丁版本，而不增加次要版本。~1.2.3 將使用從 1.2.3 到 <1.3 的版本。
