Closing until I figure a way to reproduce.

Check out this issue too: #4595

[jonauz]

This issue seems to be repeating again, or was never resolved. Should not be closed, as it's a massive blocker.

[jennifer-shehane]

@jonauz If you're experiencing a bug similar to this in Cypress, please open a new issue with a fully reproducible example that we can run since none was provided here.

I just hit this error, and in my case the culprit was that I had mismatched lockfiles (I used yarn when I should have used npm

I deleted my yarn.lock and node_modules, ran a new npm install, and committed the updated package-lock.json, and that fixed the issue

[przemuh]

I confirm - removing yarn.lock + fresh install helped in my case.

What I did:

• upgrade cypress version in package.json
• run yarn install
• commit

My build on gitlabCI constantly failed because of corrupted download (checksum).

• remove yarn.lock + run yarn install
• commit

Now it works :)

[philipboeken]

I also hit this error on the gitlab CI server (using yarn). I'm sure that #4595 does not apply to my case.
Switching from yarn (1.22.0) to npm (6.13.7) seems to resolve this issue:

• remove yarn.lock
• remove node_modules
• run npm install
• change yarn install into npm install in the .gitlab-ci.yml file
• commit

After performing these steps the job succeeded on the CI server. I prefer to use yarn, so I tried to switch back:

• remove package-lock.json
• remove node_modules
• run yarn install
• change npm install into yarn install in the .gitlab-ci.yml file
• commit

This resulted in the error again. I guess we'll use npm until this checksum mismatch with yarn is resolved.

I confirm - removing yarn.lock + fresh install helped in my case.

What I did:

* upgrade cypress version in package.json

* run yarn install

* commit

My build on gitlabCI constantly failed because of corrupted download (checksum).

* remove `yarn.lock` + run `yarn install`

* commit

Now it works :)

This did the trick for me as well! Thanks!

Hi @jennifer-shehane I think the reason this issue occurs has to do with the way Cypress informs us about new versions availability.

As you can see, the popup tells users to install instead of upgrade. This will result in two entries in yarn.lock.
The first entry is for the first install yarn add cypress which will start with cypress@*...
The 2nd one will be for installing the specific version and it'll start with cypress@3.6.1...

If the popup message shows upgrade commands instead of install i.e. yarn upgrade cypress@^3.6.1, this duplicate entries issue will go away (at least for projects that don't use yarn workspace)

[jennifer-shehane]

@mustafawm yeah, this messaging is likely not helping. I'll open a PR to update this.

Edit: opened #7101

[Ilesanmi-Erioluwa-Victor]

Fixed this bug on my window 10 64 bits system, by deleting my yarn.lock file and node_modules folder and reinstall both cypress and node_modules using npm install to install my nodule_modules and npm install cypress to also install cypress package..
I hope this work for anyone facing this bug
