error Your lockfile needs to be updated, but yarn was run with `--frozen-lockfile`

error Your lockfile.md

error Your lockfile needs to be updated, but yarn was run with `--frozen-lockfile`.

if you update your package.json only. and then run yarn install --frozen-lockfile

The above error show you on console.

it's say that you need to run just yarn install.

--fronzen-lockfile option is tell you need to update your lock.file which will be much dependency of package in your package.json.

It's possible to occure in server when you deploy. if there are your changed package.json that pushing to git repogitory already in server , But you forget to change yarn.lockfile and have not been git it, run above command (--forzen-lockfile). you notice that your forgot it.

in order to get my project going again I had to use yarn 1

I installed corepack (suggested from the [deprecated] yarn version manager)

made sure I had entries in my package.json (and deleted a .yarnrc file asking for yarn 3)

  "packageManager": "[email protected]",
  "engines": {
    "node": ">=14.19 <=16.x",
    "yarn": "=1.22.19"
  },

Then activated the yarn I wanted

corepack prepare [email protected] --activate

and then everything worked again

I also got this error in my build pipeline, just removing the ^ from dependency helped to solve the issue.

I had a problem deploying a backend app in railway and I solved doing two things:

• Removing the ^ from the dependencies
• Deleting the yarn.lock file, since it was generated on the build process and therefore, this error didn't appeared anymore

Thanks!

@irvingvjuarez can I ask where you deleted the yarn.lock file from?

Thanks!

@nik-neg you said:

if both files package.json and yarn.lock are present

I think you meant if both files package-lock.json and yarn.lock are present, right?

this solve my issue thanks
