`@parcel/fs tried to access @parcel/core (a peer dependency) but it isn't provided by its ancestors` error when following tutorial #9114

perlun · 2023-06-27T18:34:20Z

🐛 bug report

Following the general tutorial at https://parceljs.org/getting-started/webapp/ gives me the error below when trying to run yarn parcel src/index.html.

The yarn add step worked fine and added parcel properly to the my package.json.

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

`package.json`

{
  "name": "example.com",
  "packageManager": "[email protected]",
  "devDependencies": {
    "parcel": "^2.9.3"
  }
}

I don't have any .babelrc AFAICT.

🤔 Expected Behavior

The app should be built and the devserver should be started.

😯 Current Behavior

$ yarn parcel src/index.html
Server running at http:https://localhost:1234
🚨 Build failed.

@parcel/core: Failed to resolve 'src/index.html' 
@parcel/resolver-default: @parcel/fs tried to access @parcel/core (a peer dependency) but it isn't provided by its ancestors; this makes the

can you give a reproduction link? https://codesandbox.io/ will be great

Kuinox · 2023-06-28T10:51:10Z

I'm having the same issue.
simply running

yarn init -2
yarn add --dev parcel
yarn parcel index.html

triggers the problem.

Kuinox · 2023-06-28T11:13:40Z

I made a codesanbox here: https://codesandbox.io/p/sandbox/zealous-https-z83pz3
But again, simply following the getting started using yarn lead to this. There is nothing specific.

romanhrynevych · 2023-06-28T14:05:30Z

please, add @parcel/core to your dev dependencies)

And everything will work fine: link to reproduction - https://codesandbox.io/p/sandbox/gallant-haze-t9qjqh?file=%2Fsrc%2Findex.html%3A10%2C13

Also i would recommend to add index.html to src/ folder 🙂

Kuinox · 2023-06-28T14:12:00Z

That's was for the demo.

please, add @parcel/core to your dev dependencies)

The getting started doesn't mention this.

Also, this workarounds doesn't works on bigger projects:

A "stable" workaround is to put yarn pnp in "loose" mode.

romanhrynevych · 2023-06-28T14:14:42Z

The getting started doesn't mention this.

I'm a simple dev like you, i don't have permision to edit docs 🙂

Also, this workarounds doesn't works on bigger projects:

I see that parcel in your dependencies is not similar with @parcel/ packages, maybe this is an issue)

Kuinox · 2023-06-28T14:24:43Z

Ah it's just the leftover of me trying to see if it's a recent parcel change. The behavior are the same on the lastest version.

perlun · 2023-06-28T20:03:03Z

Thanks for all the feedback. 🙏 This does seem to be a real issue with following the docs with Yarn then. 🤔

(I ended up skipping Parcel for my (very simple, rudimentary) project. I detest Node.js anyway. 😉 🙈)

romanhrynevych · 2023-06-30T18:35:46Z

In conclusion to this, i think Parcel need to update docs to install @parcel/core in dev dependencies too)

Kuinox · 2023-06-30T18:48:14Z

As I said, it doesn't solve the issue on larger projects.

FYI, Yarn's own E2Es are also broken because of this: https://github.com/yarnpkg/berry/actions/runs/5794322982/job/15703692932

blutorange · 2023-08-15T11:26:13Z

I agree that the proper solution is to fix the dependencies in the corresponding packages. What you can do as a workaround is to use yarn's package extension mechanism, e.g. by putting something like the following into your .yarnrc.yml

packageExtensions:
  "@parcel/node-resolver-core@*":
    dependencies:
      "@parcel/core": 2.9.3

For projects with multiple workspaces, this applies the extensions to all of them.

You might need to add @parcel/core to @parcel/types as well, if you use that, as I'm getting a warning here as well:

➤ YN0002: │ @parcel/types@npm:2.9.3 doesn't provide @parcel/core (pf46c3), requested by @parcel/fs
➤ YN0002: │ @parcel/types@npm:2.9.3 doesn't provide @parcel/core (p16f90), requested by @parcel/workers
➤ YN0002: │ @parcel/types@npm:2.9.3 doesn't provide @parcel/core (p385c8), requested by @parcel/cache
➤ YN0002: │ @parcel/types@npm:2.9.3 doesn't provide @parcel/core (p76fb9), requested by @parcel/package-manager

Fixes parcel-bundler#9114

olivier-spinelli · 2023-10-11T19:26:27Z

Any progress on this? I'm stuck.
Tried the:

packageExtensions:
  "@parcel/node-resolver-core@*":
    dependencies:
      "@parcel/core": 2.9.3

No luck.

parcel-bundler/parcel#9114

perlun · 2023-11-01T20:49:53Z

@olivier-spinelli Sorry to hear that. What's the error you're seeing, the same as in my original issue description?

olivier-spinelli · 2023-11-03T11:20:01Z

Sorry for the delayed answer.
Yes, it's the same peer dependency error. I've been forced to switch to Vite.

dsimonov-lionsgatewt · 2024-01-05T19:38:20Z

[TEMP SOLUTION] I had to create .yarnrc.yml file in the root of my project and add the following in it:

packageExtensions:
  "@parcel/node-resolver-core@*":
    dependencies:
      "@parcel/core": 2.9.3
  "@parcel/types@*":
    dependencies:
      "@parcel/core": 2.9.3
  "@parcel/fs@*":
    dependencies:
      "@parcel/core": 2.9.3

Save file and run yarn install a few times
Try building again

My package.js devDependencies looks like this now (ignore the packager-raw-url, transformer-webmanifest):

"devDependencies": {
    "@parcel/packager-raw-url": "2.11.0",
    "@parcel/transformer-webmanifest": "2.11.0",
    "parcel": "^2.11.0"
  }

Everything works now. Hope it helps someone.

bartek-szymanski · 2024-01-26T22:20:36Z

In my case I don't have this issue after switching to npm.
