Cypress: Failed to deserialize the V8 snapshot blob error during 'run' and 'open in Windows - 3.5.0

Created on 24 Oct 2019 · 28Comments · Source: cypress-io/cypress

Current behavior:

cypress run and cypress open, yield the following error after upgrading to 3.5.0:

Cypress failed to start.

This is usually caused by a missing library or dependency.

The error below should indicate which dependency is missing.

Hey @dugajean, thanks for opening this issue. This is likely isolated to something about your environment specifically.

In order to address you issue as quickly as possible, could you run Cypress in debug mode mode and print the entire set of logs here? Thanks!

Can you also put information about where you are runinng this from? What CI?

@jennifer-shehane I'm running this on my local machine. I'll run Cypress in debug mode and provide the output here.

@jennifer-shehane I have tried deleting node_modules and running yarn again from scratch, but that didn't help either.

I also got the "Failed to deserialize the V8 snapshot blob". Renaming the Cyrpress cache folder and reinstalling with npx cypress install resolved the problem though. Previously I upgrade the Vue CLI and had multiple errors here and interrupts. In my case, I think Cypress simply wasn't install correctly. Just for information for your troubleshooting.

@AsthirWP where's that cache folder located?

dugajean on 25 Oct 2019

On Windows, it's in \AppData\Local\Cypress\Cache\

This fix worked for me!

This fix worked for me too!

dugajean on 26 Oct 2019

yup, clearing the cache (renaming the above cache folder) and reinstalling cypress fixed this issue.

karlcp on 28 Oct 2019

Worked for me too! Didn't have to clear the cache though, only force reinstall.

Thanks kristianfjelde

basvanlaarhoven on 6 Nov 2019

I just had this happen to me because I accidentally closed out before installation had completed.

JGurganus12 on 7 Nov 2019

with yarn:

remove cypress from node_modules
yarn install --check-files

Joining the npx cypress install --force bandwagon, problem solved for me.

We'll be closing this issue as resolved. Please follow the workaround above for clearing cache during install if you see this error.

@kristianfjelde you saved my day (and my sanity), thanks a lot!

gianlucabaldin on 7 May 2020

I have to find this thread and rename the cache folder every time I upgrade Cypress. Hoping this gets fixed.

Camineet on 7 May 2020

For some reason I seem to be needing to do this a lot lately: npx cypress install --force Not sure why.

kees0 on 9 Jun 2020

At our company it seems to happen to one or two / 100 employees every time we upgrade.

lukeapage on 1 Oct 2020

Also happened to me today on a new install.
FYI: on local machine, Windows 10, Cypress 4.4.0, using yarn. The above fix worked: yarn run cypress install --force
