我无法从preset-es2015成功更新babel。每当我尝试通过NPM安装软件包时，都会收到警告：
npm WARN已弃用babel-preset-es2015@6.24.1：感谢您使用Babel：我们建议立即使用babel-preset-env：请阅读babeljs.io/env进行更新！
但是，当我遵循babeljs.io/ev给出的建议并运行命令
npm install babel-preset-env --save-dev
我收到多个“ gyp ERR！”和“ npm ERR！”错误，像这样

我无法找到任何解决办法。我尝试了各种安装和更新babel的方法。任何帮助将不胜感激。
重新安装npm后出现最新错误：
