`npm i core-js@latest` 不会安装，因为它无法构建... core-js@<3.3？

Question

我正在尝试为一个旧的、未维护的库恢复构建，以便我们可以检查一些更改（或发布一个分支），让它与另一个更新的库（即 Bootstrap 4，但这对这个问题并不重要）一起很好地发挥作用） .

在尝试 vanillanpm i时，首先我发现了一些地方，因为~vs^冲突，库的 package.json 与其依赖项的依赖项发生冲突——依赖项对版本更宽容，所以我将主项目中的一些依赖项从~改为^匹配。没什么大不了。

但后来…… npm i在它最终放弃之前，它陷入了看起来像是正在建造的东西的地方。

在它似乎挂起之前显示的最后一行是这样的：

?                  ? ? reify:rxjs: timing reifyNode:node_modules/selenium-webdriver Completed in 8604ms

然后，它调用clang和make遍地的一段时间（在MacOS大苏尔，我可以看到在终端的标题栏中的命令），最后才重新进入npm i和呕吐所有的地方。

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3.3 is no longer maintained and not recommended for usage due to the number of issues.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.
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3.3 is no longer maintained and not recommended for usage due to the number of issues.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.
npm ERR! code 1
npm ERR! path /Applications/projects/angularjs-dropdown-multiselect/node_modules/node-sass
npm ERR! command failed
npm ERR! command sh -c node scripts/build.js

这个问题似乎至少是相似的，因为它有类似的问题node-sass，但是库node-sass在它的 package.json中没有任何地方，这表明它是一个依赖项的依赖项，它正在抓取 node-sass ......所以我不是确定如何从我所在的位置编辑 node-sass 依赖项，而无需猜测很多依赖项版本。

尝试安装 core-js@latest

好的。让我们尝试安装大于3.3 的core-js ，看看我们是否可以强制它以某种方式工作。

事实上，让我们尝试获取最新的（看起来是3.13 atm）...

npm i -D core-js@latest

这是奇怪的事情：

这给了我同样的错误！

就像字面上相同的东西：

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3.3 is no longer maintained and not recommended for usage due to the number of issues.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 core-js@<3.3 来构建？

这里发生了什么？

更多日志！

我将尝试从npm Err!上面粘贴后的日志熨平板中选择看起来有用的东西，以防万一。需要明确的是，这是在第一次尝试npm i为整个库，以及IS NOT的npm install -D core-js@latest。

恐怕这超出了我的工资水平。这是怎么回事？

不确定您是否仍在寻找答案，但万一其他人这个命令对我有用：

npm install --save core-js@^3
