Installing cypress with ZScaler Proxy

Question

When I'm trying to install Cypress with the Zscaler Cloud Connector on a Windows 10 machine, I get the following error:

I followed the suggestions at https://on.cypress.io/proxy-configuration and set the HTTP_PROXY environment variable to match what's displayed in the Script address of the Proxy Settings. (Here it is displayed in a cmd prompt):

C:\Windows\system32>echo %HTTP_PROXY%
http://127.0.0.1:9000/systemproxy-9a8d7abc.pac

I've tried installing cypress using a new Power Shell prompt after setting the environment variable, in case my old Power Shell prompt had a stale environment.

However, I still get the same error. In the Zscaler settings I've tried temporarily turning off the Service Status, but it still fails with the same error.

I was able to come up with a workaround based on the instructions here: while installing cypress through command:npm install cypress --save-dev getting error as The Cypress App could not be downloaded

In cmd I ran:

set CYPRESS_INSTALL_BINARY=C:\Users\eric\Downloads\cypress.zip

followed by:

npm install cypress --save-dev

I tried doing it in power shell, but if I ran a:

set CYPRESS_INSTALL_BINARY=~/Downloads/cypress.zip
dir env:

It wouldn't show me the CYPRESS_INSTALL_BINARY in my environment.

Note that I had to switch to an absolute path in cmd, because it didn't understand ~

I then realized that I needed an older version of cypress, so I tried doing a:

npm uninstall cypress

up to date, audited 509 packages in 970ms

  run `npm fund` for details

but it doesn't seem to have fully uninstalled, because I see:

c:\MyPath>npx cypress run

There is a cypress.json file at the path: c:\MyPath

Cypress version 10.0.0 no longer supports cypress.json.

Please run cypress open to launch the migration tool to migrate to cypress.config.{js,ts,mjs,cjs}.

I realized that although the npm cypress uninstall appeared to have worked. I still had files left in the C:\Users\eric\AppData\Local\Cypress directory. I deleted these files and reinstalled cypress 9.6.1 after downloading it from https://download.cypress.io/desktop/9.6.1 Doing a

set CYPRESS_INSTALL_BINARY=C:\Users\eric\Downloads\cypress_old.zip

and then a

npm install cypress

and I was able to run

npx cypress run

without it complaing that

Cypress version 10.0.0 no longer supports cypress.json.
