transformer-babel error: Unknown option: .showIgnoredFiles (Nightly 598)

🐛 bug report

With nightly 598, our build fails right away on the following error:

Not sure where the error is coming from, but I can see shoeIgnoredFiles on the Babel website. Note this issue was not happening with Nightly 577 where we could build fine.

Also, prior to this issue, I ran into #5854 (Which also did not happen with nightly 577) and so I added these packages in the monorepo root package.json to overcome and disabled auto install:

    "@parcel/transformer-posthtml": "^2.0.0-nightly.600",
    "@parcel/transformer-html": "^2.0.0-nightly.600",
    "@parcel/packager-html": "^2.0.0-nightly.600"

Also tried adding @parcel/transformer-babel but it didn't make a difference.

🎛 Configuration (.babelrc, package.json, cli command)

Babel:

module.exports = function (api) {
  api.cache(true);

  return {
    presets: [
      [
        '@babel/preset-env',
        {
          bugfixes: true,
          corejs: 2,
          useBuiltIns: 'entry'
        }
      ],
      '@babel/preset-react',
      '@babel/preset-typescript'
    ],
    plugins: [
      '@babel/plugin-proposal-class-properties',
      ["@babel/plugin-proposal-decorators", {decoratorsBeforeExport: true}]
    ]
  }
};

🤔 Expected Behavior

Build should be successful.

😯 Current Behavior

Build fails almost immediatelly.

💁 Possible Solution

💻 Code Sample

I can provide access to @devongovett (Same company). Can also try to do a minimal reproduction if required.

🌍 Your Environment

Software	Version(s)
Parcel	2.0.0 nightly 598
Node	14/15 (latest)
npm/Yarn	latest
Operating System	CentOS / Mac OS

The flag showIgnoredFiles was set as part of #5769.

It was added in @babel/core v7.12.0. I'd say you're using an older version somehow?

@devongovett This is another case of the babel transformer not having a hard dependency on babel core. Otherwise there would have been ^7.12.0:

parcel/packages/transformers/babel/package.json

Line 43 in 2470d3c

"@babel/core": "^7.12.0"

[ittaibaratz]

@mischnic this goes beyond my Babel knowledge .. We are using @babel/core, however we are also using Testcafe for integration tests which imports babel-core 6:

From our yarn.lock:

"@babel/core@^7.1.0", "@babel/core@^7.12.13", "@babel/core@^7.12.3", "@babel/core@^7.4.4", "@babel/core@^7.7.5":
  version "7.12.13"

babel-core@^6.22.1, babel-core@^6.26.0:
  version "6.26.3"

Should we add babel-core as a dev dependency to resolve this? Will try.

[mischnic]

Sorry, I meant @babel/core, not babel-core

What version is installed at /Users/ittai/Documents/GitHub/unified-shell/node_modules/@parcel/transformer-babel/node_modules/@babel/core/package.json ?

[devongovett]

That should cause yarn/npm to give incompatible peer dep warnings which is the best we can do I think

[ittaibaratz]

@mischnic 7.10.4 - I don't see it in yarn.lock though, I'll try to do a clean install.

[ittaibaratz]

Ok, a clean install solved. Closing. Thanks for the quick reply!

It was added in @babel/core v7.12.0. I'd say you're using an older version somehow?

Your package.json:

"devDependencies": {
   "@babel/cli": "7.11.6",
   "@babel/core": "7.11.6",

That's strange. npm-check-updates doesn't suggest me @babel/core 7.12.0. I thought my deps are up-to-date.

npm-check-updates correctly suggests the latest:
