npm install 安装模板不成功？

下载了 PanJiaChen/vue-admin-template 的模板，但 npm install 安装不成功（把镜像换成了淘宝的镜像）。
显示:

npm warn deprecated core-js@2.6.12: core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js.

从你提供的错误信息来看，主要问题出在 node-sass 的编译过程中，特别是与 Python 相关的依赖。node-sass 需要 Python（通常是 Python 2.x，但现在更推荐使用 Python 3.x，并且确保版本与 node-gyp 兼容）来编译一些本地模块。此外，core-js 版本过旧也是一个需要注意的问题，但这不是导致 npm install 失败的主要原因。

以下是一些解决步骤：

更新 Python：
确保你的系统上安装了 Python。由于 Python 2.x 已经不再维护，建议安装 Python 3.x（如 Python 3.7 或更高版本）。安装后，确保 Python 的可执行文件路径被添加到了系统的环境变量 PATH 中。
安装或更新 node-gyp：
node-gyp 是一个用于编译原生 Node.js 模块的跨平台工具。你可以通过 npm 安装或更新它：
```
npm install -g node-gyp
```
全局安装 Windows 构建工具：
如果你使用的是 Windows，并且 npm 报告缺少编译工具，你可能需要安装 Windows 构建工具。这可以通过运行以下命令来安装（可能需要管理员权限）：
```
npm install --global --production windows-build-tools
```
考虑替换 node-sass：
由于 node-sass 依赖于 Node.js 的原生模块编译，这可能导致跨平台兼容性问题。考虑将 node-sass 替换为 sass 或 dart-sass，它们通常更稳定且易于安装：
```
npm uninstall node-sass
npm install sass --save-dev
```
然后你可能需要在你的项目中修改引用 node-sass 的部分以使用 sass。
清理 npm 缓存：
有时候，清理 npm 的缓存可以解决一些奇怪的安装问题：
```
npm cache clean --force
```
重新运行 npm install：
在进行了上述更改后，尝试再次运行 npm install。
检查 npm 日志：
如果问题仍然存在，检查 npm 日志文件（如你提供的路径中的 2024-07-28T06_16_21_102Z-debug-0.log）可能会提供更多关于错误原因的线索。

通过这些步骤，你应该能够解决 npm install 过程中的问题。如果问题仍然存在，可能需要更详细地检查项目的依赖和配置。
