How do I pass environment variable in script command – Javascript

I have below cypress nodeJS script commands in package.json

"scripts": {
"cy:run": "npx cypress run --browser chrome",
"cy:parallel" : "cypress-parallel -s cy:run -t 4 -d cypress/e2e/features/ -m false -a '"--env ENV=${ENVI}"'" 
}

-a is the argument that is dynamic, That I want to pass while running the tests like ENVI=QA or ENVI=LIVE

I have tried following things but did not work for me

SET ENVI=QA
npm run cy:parallel

ENVI=QA npm run cy:parallel

$ENVI=QA npm run cy:parallel

Please share the correct way to pass the argument from the command-line

    It worked for me with below command:

    set the environment variable value like below:

    $env:ENVI=QA (On Windows)

    and change script command as follow:

    Instead of ENV=${ENVI}, Use ENV=%ENVI%

    "cy:parallel" : "cypress-parallel -s cy:run -t 4 -d cypress/e2e/features/ -m false -a '"--env ENV=%ENVI%"'"

    One way would use CYPRESS_ prefix.

    To make things easier (independent of OS) use the package cross-env.

    Install

    npm install --save-dev cross-env

    package.json

    "scripts": {
  "cy:run": "cross-env CYPRESS_ENVI=QA cypress run",
  ...
}

    Tested with a simple test:

    it('checks cross-env has set up CYPRESS_ENVI', () => {
  expect(Cypress.env('ENVI')).to.eq('QA')                // passes
})

    You can use -- to separate the npm command from the cypress command, and everything after it is passed as arguments to the cypress-parallel command:

    npm run cy:parallel -- --env ENV=QA
