Current behavior:

Desired behavior:

The update process should end without affecting any important component of cypress, now cypress does not work and the only way to solve this is copy and paste the cypress folder that I have on my back up

Current cypress version: 4.7.0
Desired cypress versioin: 4.8.0
Windows 10 Enterprise
Node js V12.18.1

It looks like something failed during the postinstall of the Cypress package, so it never fully installed the npm module as shown in the warnings. If the install fails, then the module will not be present to run.

I'm not sure why the postinstall is failing in this case however. Looks to be a duplicate of #6807
