Try using the below command from your project folder:
尝试使用项目文件夹中的以下命令：
npm audit fix
npm audit fix
If it still shows it has fixed only few of the vulnerabilities, then use the below command
如果它仍然显示它只修复了几个漏洞，则使用以下命令
npm audit fix --force
npm audit fix --force

This warning told everything:
这个警告说明了一切：
Unsupported platform for [email protected]: **wanted** {"os":"darwin","arch":"any"} (**current**: {"os":"win32","arch":"x64"})
Only unix-based systems use fsevents, and You are using Windows!
只有基于 unix 的系统使用fsevents，而您使用的是 Windows！

First of all, all the things you have posted are Warningsand not errors.
首先，您发布的所有内容都是警告而不是错误。
It means the npm has skipped the dependencies.
这意味着 npm 已跳过依赖项。
This would be solved if you update the npm version to the latest, use this command:
如果您将 npm 版本更新为最新版本，则可以解决此问题，请使用以下命令：
npm i -g npm@latest
// use sudoif you get permission error.
//如果出现权限错误，请使用sudo。
and try to install again.
并再次尝试安装。
Hope this helps.
希望这可以帮助。
