我正在尝试在节点中安装@ babel / preset-env，并且出现以下问题
npm install @babel/preset-env --save-dev

尝试这些解决方案之一
npm cache verify --force packages-lock.json npm cache clean --force node_modules 答案 1 :(得分：0)
通常，这意味着您的本地npm缓存或package-lock.json已损坏，导致npm注册表中@babel/preset-env的完整性哈希与{{1}中的内容不同}。我将按此顺序执行这些步骤。
package-lock.json rm -rf node_modules rm package-lock.json npm cache clean -f npm cache verify -f 这将删除您拥有的所有缓存数据，并迫使npm登录注册表以获取新的软件包数据，并重新生成npm i以使用更新的完整性哈希。
