我正试图恢复一个旧的、未维护的库的构建，这样我们就可以签入一些更改(或发布一个fork(，让它与另一个更新的库(即Bootstrap 4，但这对这个问题并不重要(配合得很好。
在尝试普通的npm i时，首先，由于~和^的冲突，我发现库的package.json与其依赖项的依赖项发生了冲突——依赖项对版本更宽容，所以我将主项目中的一些依赖项从~更改为^以匹配。没什么大不了的。
但是npm i陷入了困境，在它最终放弃之前，它看起来像是在建造什么。
在它似乎挂起之前显示的最后一行是：
⸨ ⸩ ⠴ reify:rxjs: timing reifyNode:node_modules/selenium-webdriver Completed in 8604ms
然后它一遍又一遍地调用clang和make一段时间(在macOS Big Sur上，我可以在终端的标题栏中看到命令(，最后重新输入npm i并吐得到处都是。
呕吐开始于：
npm WARN deprecated connect@1.9.2: connect 1.x series is deprecated
npm WARN deprecated core-js@1.2.7: core-js@<3.3 is no longer maintained and not recommended for usage due to the number of issues.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. Please, upgrade your dependencies to the actual version of core-js.

这个问题看起来至少很相似，因为它与node-sass有类似的问题，但该库的package.json中没有node-sass，这表明它是一个依赖项的依赖项，该依赖项正在抓取节点sass。。。所以我不知道如何在不猜测很多依赖版本的情况下，从我所处的位置编辑节点sass依赖。
正在尝试安装core-js@latest
好的，好的。让我们试着安装大于3.3的corejs，看看我们是否可以强迫它以某种方式工作。
事实上，让我们试着获取最新的(看起来是3.13个大气压(。。。
npm i -D core-js@latest
奇怪的是：
这给了我同样的错误
就像在字面上一样：
npm WARN deprecated core-js@2.6.12: core-js@<3.3 is no longer maintained and not recommended for usage due to the number of issues.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. Please, upgrade your dependencies to the actual version of core-js.
嗯？core-js@latest需要核心js@<3.3建造？
这是怎么回事？
更多日志记录
我将在上面粘贴的npm Err!之后，尝试从原木熨平板中选择看起来有用的东西，以防有用。需要明确的是，对于整个库，这是第一次尝试npm i，对于npm install -D core-js@latest，不是。

恐怕这超出了我的工资等级。怎么回事？
