'export' in .env is causing issues when deploying contract to a test net

[jedecast]

export KOVAN_RPC_URL='www.infura.io/asdfadsfafdadf'
export PRIVATE_KEY='abcdef'
export ALCHEMY_MAINNET_RPC_URL="https://eth-mainnet.alchemyapi.io/v2/your-api-key"

causes:

failed to get chainId, falling back on net_version...
An unexpected error occurred:

ProviderError: Must be authenticated!

removing 'export' will fix the issue

KOVAN_RPC_URL='www.infura.io/asdfadsfafdadf'
PRIVATE_KEY='abcdef'
ALCHEMY_MAINNET_RPC_URL="https://eth-mainnet.alchemyapi.io/v2/your-api-key"

Have you tried using "import" instead?

I started with just $200 and, with the help of a skilled and disciplined trader, grew my account to $29,000. His accurate market analysis and strong risk management made it possible. On ƭεℓεɠɾαɱ @Adelynnrichardsonfx I’m truly grateful for the guidance and consistent results.
