Answer 1

试试这些解决方案之一

1. npm cache verify --force
2. 删除packages-lock.json
3. npm cache clean --force
4. 删除node_modules

Answer 2

通常，这意味着您的本地 npm 缓存或您的 package-lock.json 已损坏，导致 npm 注册表中的@babel/preset-env完整性哈希与您package-lock.json中的完整性哈希不同。我会按这个顺序执行这些步骤。

1. rm -rf node_modules
2. rm package-lock.json
3. npm cache clean -f
4. npm cache verify -f
5. npm i

这应该会删除您拥有的任何缓存数据，并强制 npm 访问注册表以获取新的包数据，并重新生成package-lock.json以使用更新的完整性哈希。
