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. Please, upgrade your dependencies to the actual version of core-js.

Thank you for using core-js ( https://github.com/zloirock/core-js ) for polyfilling JavaScript standard library!

The project needs your help! Please consider supporting of core-js on Open Collective or Patreon:

虽然应该是 npm 的问题，但还是给遇到相似问题的人一些提示。如果遇到类似问题，npm install -g npm@6 版本回退即可；
另外，用yarn安装是不会产生问题的。

@darkXmo 更新了依赖列表，你可以用 npm@7 试试看安装依赖正常了没有。

换了个错误报，过于痛苦，我还是选择 yarn 来安装依赖吧。

这个看上去显示 gyp 的问题

安装 sqlite3 会依赖 node-gyp，windows 平台不大容易装上，可能需要安装 Visual Studio （非VSCode）。你是 MacOS 吧应该没问题。
我这儿 CI 的 alpine 镜像用 npm7 安装是正常的，你可以参考下：

1. 安装 python3 ，比如 apk add python3
2. 设置路径， npm config set python /usr/bin/python3
3. 项目安装依赖 npm i --legacy-peer-deps
