Can't install cypress

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:

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

> cypress@6.6.0 postinstall C:\Code\CypressTest\node_modules\cypress

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?

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

[jennifer-shehane]

@steverb1 That is not expected behavior. This can happen if you have 2 Cypress applications running at the same time. https://github.com/cypress-io/cypress/issues/5613

I think it may also happen if you are connecting to the chrome debugging port in some other manner https://github.com/cypress-io/cypress/issues/14835

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