Can't install cypress

[steverb1]

I'm trying to install cypress, there is as proxy involved. I've read everything on the Cypress web site about proxies and tried everything I know to try. Still can't install it.
I'm doing this from a PowerShell window.

Here's the setup:
I have a .npmrc file with
registry=https://{address of our internal npm repository}

I have verified that Cypress is there.

In the PowerShell window, before installing I do:

$env:HTTP_PROXY = "{our internal proxy}"
npm config set registry https://{same address above, to internal npm repository}

After "npm install cypress" I get this error:

===================================================

> node index.js --exec install

Does your workplace require a proxy to be used to access the Internet? If so, you must configure the HTTP_PROXY environment variable before downloading Cypress. Read more: https://on.cypress.io/proxy-configuration

Otherwise, please check network connectivity and try again:

Any ideas on what I am missing?

Try also adding https_proxy, HTTPS_PROXY and http_proxy, maybe even all_proxy.
I dont know what it was but Cypress requires either upper or lowercase🤔
additionally npm config set proxy / npm config set https-proxy might help

[jennifer-shehane]

@cbruge The proxy configuration is not sensitive to capitalization: https://github.com/cypress-io/cypress/blob/develop/cli/lib/tasks/download.js#L19:L19

[cbruge]

@jennifer-shehane thats great news! Maybe I mixed things up, have been using Cypress since v3.x🙈

[steverb1]

So, I ended up installing it from the binary. Now, when trying to run my first sample test, I get:

 Cypress failed to make a connection to the Chrome DevTools Protocol
 Error: connect ECONNREFUSED 127.0.0.1:51606

I'm sure this is something to do with the internal company network (it is locked down pretty good) but I don't know where to start. What kinds of questions do I need to ask our security folks?

[steverb1]

Now, seeing other people have had this same issue in the past. So maybe not related to our company network. Is there a resolution for this? Running Cypress 6.6.0

[steverb1]

Also, I can run a test in Cypress successfully in Edge, but not Chrome.

[steverb1]

Here's an update: I can run Cypress with Chrome, but only if Chrome is not already open. If Chrome is already open I get the error "Cypress failed to make a connection to the Chrome DevTools Protocol".
Is that the expected behavior?
If so, can you warn users that Chrome should not be running prior to firing up Cypress?

[jennifer-shehane]

@steverb1 That is not expected behavior. This can happen if you have 2 Cypress applications running at the same time. #5613

I think it may also happen if you are connecting to the chrome debugging port in some other manner #14835

But I haven't seen that error in a while outside of those reasons.

This issue has not had any activity in 180 days. Cypress evolves quickly and the reported behavior should be tested on the latest version of Cypress to verify the behavior is still occurring. It will be closed in 14 days if no updates are provided.
