node v14

dotenv@^16.0.0
dotenv-cli@5.1.0 (with required dotenv-expand@^8.0.1 )

Works ONLY with no such error when I downgrade to dotenv-cli@4.1.1 which under the hood installs dotenv-expand@^5.1.0

Seems like a bug in dotenv-expand. Not sure why the newer version doesn't work but nothing we can do about that. I'm pretty sure dotenv-expand as a library will have the same bug

experiencing this on dotenv 5

I found that this is related to some special-chars in my .env. Commenting those lines out avoids the error. But yes, this is still a bug in dotenv-expand.

@wilsonpage You are right.

This is kinda stupid. I have a $ sign inside my .env file as it is part of a password and now this library doesnt work because of that ?

[entropitor]

Try quoting it, if it doesn't work, file a bug over at dotenv-expand as "this library" doesn't do any parsing.

Hi :) Good to see some activity under my issue, which had been closed already by @entropitor - but it's ok.

I wanna say, that that at the time of report I'd experimenting with cross-env dotenv and dotenv cross-var and a few other approaches to somehow bring variable from .env to package.json. And now considering that MY .env file has many other things, I will research (cleanup/delete/etc) and will update this ticket later.

Here is my full list of experiments:

    "cypress:run": "cypress run",
    "cypress:run:new1": "cross-env CYPRESS_BASE_URL=http://localhost cypress run",
    "cypress:run:new2": "cross-env dotenv cypress run",
    "cypress:run:new3": "cross-env dotenv cross-var cypress run",
    "cypress:run:new8": "export $(cat .env | xargs) && npm run cypress:run:auth",
    "cypress:run:new9": "export $(cat .env | grep \"^[^#;]\" | xargs) && cypress run",
