Private repo install fails with "[TypeError] quote_from_bytes() expected bytes"

• I am on the latest Poetry version.
• I have searched the issues of this repo and believe that this is not a duplicate.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Debian GNU/Linux 10 (buster)
• Poetry version: 1.0.0
• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/daniellehanks/25b972d4a28c1ff73cfe17f00c9da9b3

Issue

When running poetry install where I have a private repo, it usually fails (but sometimes works, can’t seem to figure out why) with [TypeError] quote_from_bytes() expected bytes.

Using Python 3.7. Performing this inside a Docker container on CircleCI if that matters.

Example values below where values match what they should in pyproject.toml, but may be changed from the actual values we use. I have also tried this by setting POETRY_HTTP_BASIC_FOO_USERNAME and POETRY_HTTP_BASIC_FOO_PASSWORD as environment variables instead of with the config option with the same result.

PYPI_REPOSITORY=foo
PYPI_URL=https://pypicloud.redacted.com/simple/
PYPI_USERNAME=username
PYPI_PASSWORD=my_password

poetry config repositories."$PYPI_REPOSITORY" "$PYPI_URL" && poetry config http-basic."$PYPI_REPOSITORY" "$PYPI_USERNAME" "$PYPI_PASSWORD" && poetry install -vvv
Skipping virtualenv creation, as specified in config file.
