Error When Making a PyPi Package

So I am making a Python Framework that I want to publish on PyPi so people can easily import the code without having to use the source code.
But when I am putting the commands in the shell →

poetry new vial
cd vial
poetry update

The error happens and says Illegal character ‘\n’ (line 4, column 115)
But I can’t seem to find/fix the error.

You accidently typed a newline on line 4-5 of vial/pyproject.toml, so if you delete that, it should work.


@Fairies0feast ok that worked, but after

poetry build
poetry publish

It throws an error and doesn’t ask for credentials like it normally does.

Do you have 2FA enabled?
Is the version a new version?

Tbh I recommend using project tokens, even if you don’t have 2FA on.

@Firepup650 how would I use project tokens (sorry for the dumb question, I have never used secrets/tokens before), also how would I use them for the publishing of the package?


  1. Go to
  2. Login if you’re not
  3. Give the key a name, select the token’s scope (I suggest doing it per-project so that if it’s ever compromised the damage is minimal)
  4. (Technically optional, but I recommend it so you don’t have to remember the token) Set a secret called something like PYPI_TOKEN to the token pypi gave you
  5. Run poetry publish -u __token__ -p $PYPI_TOKEN, where $PYPI_TOKEN is the secret pointing to your token, or just paste the token there. (Do NOT change -u __token__, that is the correct username for all tokens)
  6. Profit
