cypress install no_proxy not working ?

[pagadalacs]

Current behavior:

node:11.7.0
npm:6.5.0
cross-env: 7.0.2

my package.json file :

"scripts": {
    ...
	"preinstall": "npm install --no-package-lock cross-env run-script-os rxjs && npm run install:cypress",
    "install:cypress:linux": "cross-env CYPRESS_INSTALL_BINARY=https://internal.nexus.repo/cypress/4.0.2/cypress-4.0.2-linux-x64.zip npm install cypress@4.0.2 --save-exact",
    ...
  },

npm install always trying to use http_proxy it seems, and apparently it fails, since its our internal repo doesn't need proxy. i added in no_proxy=.nexus.repo environment variable to bypass proxy. I have proxy and no_proxy configured in environment variables and also in .npmrc also. Looks like no_proxy option not working in this case ? Any help us appreciated ?

Desired behavior:

cypress install should ignore proxy

output on jenkins :

npm info lifecycle cypress@4.0.2~postinstall: cypress@4.0.2

cypress@4.0.2 postinstall /opt/jenkins/workspace/npm_testjob/node_modules/cypress
node index.js --exec install

⚠ Warning: Forcing a binary version different than the default.

The CLI expected to install version: 4.0.2

Instead we will install version: https://internal.nexus.repo/cypress/4.0.2/cypress-4.0.2-linux-x64.zip

These versions may not work properly together.

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:

I solved the issue, its workaround : configured cntlm proxy , that able to bypass proxies for all the internal repos or all domains menioned in "noProxy" . just in case somebody is struggling with same issue as above.

so in env :

export http_proxy = http:/10.0.0.10:3128 ( cntlm proxy)
in cntlm proxy :

 Proxy           http://corporateproxy     
 NoProxy         localhost, 127.0.0.*, .nexus.repo
