npm install cypress often fails with download timeout

[bjowes]

Current behavior:

´npm install cypress´ often fails with download timeout from our environment.

Desired behavior:

´npm install cypress´ should have a higher default timeout, and possibly an environment variable to set the timeout.

Test code to reproduce

Install cypress on a machine with low bandwidth internet connection.

Versions

Cypress 5.0.0.
Download worked fine with version 4.7.0 (last time we updated) and it seems the size of the zip file has increased a bit since then. We used to have the same problem with older versions of cypress, when the zip files were >200 MB.

Help offered

If the desired behavior is considered something that could improve cypress, I would be happy to provide the PR for it.

Can you provide the full error text that displays when this happens? Would like to see where/what is timing out exactly.

[bjowes]

Sure, see the log below. I timed it, the download times out after 80 seconds.

c:\Source\Repos\xyz\e2e>npm i cypress@5

> cypress@5.0.0 postinstall c:\Source\Repos\mpa_keps\e2e\node_modules\cypress
> node index.js --exec install

This happened to us as well while deploying using GH Action.

Any update on this @jennifer-shehane ?

[bjowes]

Update: Installing 5.1.0 works so far, will need to test it further to see if it is just luck with the bandwidth

[lourenci]

This is happening frequently in my CI environment too:

This is occurring in my project ci too after upgrade cypress@6.0 from cypress@5.6, there is install log.
https://github.com/laststance/create-react-app-typescript-todo-example-2020/runs/1453253415

wired thing is log says Installing Cypress (version: 5.6.0) despite upgraded to cypress@6.0 already.

[ryota-murakami]

After investigation I figure out cypress@5.6.0 in a yarn.lock.
So I run rm yarn.lock and yarn install to renew yarn.lock, this resolved.

[wachunga]

At least some of these issues are likely related to 2 different versions of cypress, which is logged here: #4595

[ryota-murakami]

@wachunga thanks about that information!

[jennifer-shehane]

Closing since the original issue was resolved.

If you're getting a checksum error: Expected downloaded file to have checksum: you are experiencing this issue. #4595
