Does not support dependencies that depend on core-js@3

[hq001]

Bug report

Steps to reproduce

If I use the following configuration it won't compile.
Core-js@3 is already installed in the package I depend on, but it still prompts me that I cannot find the corresponding core-js module. I tried to change core-js to a top-level dependency, but some modules were not found. I found out that this was caused by the core-js version. I guess it is because vuepress has some problems when parsing the module.

Another point is that it is possible to optimize the logs of the vuepress build docs. I found that if there is no module found, all the logs of webpack will be output.

{
  "presets": [
    [
      "@babel/preset-env",
      {
        "useBuiltIns": "usage",
        "corejs": {
          "version": 3,
          "proposals": true
        }
      }
    ]
  ]
}

I changed the version of core-js to 2 to compile successfully. Is this a vuepress issue? I use vuepress build docs

Also having this issue.

Was having the same issue. Have core-js@3 in the main package.json so Vuepress is unable to find the differently named modules from core-js@2.

My workaround is tweaking the script that builds Vuepress to first remove core-js and re-add it afterwards. It's a bit of a mess, but I haven't found a better solution to use Vuepress in a project that relies on core-js@3.

yarn remove core-js && vuepress build docs && yarn add core-js
