ModuleNotFoundError for keyring.util.escape in Docker image (poetry 1.0.0 and 1.0.0b9)

• 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: MacOS 10.14.6, running docker. Docker image is nvidia/cuda:10.2-cudnn7-devel-ubuntu18.04
• Poetry version: Both 1.0.0b9 and 1.0.0

Issue

Attempted an install of poetry in my docker file. The install succeeds, but running any poetry commands gives a strange error. I’ve shown the docker build (trimmed down) along with the error below.

Retrieving Poetry metadata

# Welcome to Poetry!

This will download and install the latest version of Poetry,
a dependency and package manager for Python.
.................................................

Poetry (1.0.0) is installed now. Great!

To get started you need Poetry's bin directory ($HOME/.poetry/bin) in your `PATH`
environment variable. Next time you log in this will be done
automatically.

To configure your current shell run `source $HOME/.poetry/env`

I believe this indicates that poetry needs to vendor keyrings.alt, or at least update the required version of it, in order to fix this bug. A temporary workaround is to run pip install -U keyrings.alt before installing poetry, but ultimately this is something that should be fixed in poetry itself.

@abn To clarify, the PR you submitted was for the Unicode error or the ModuleNotFound error?
