poetry install can't find chrome-devtools-protocol (^0.4.0)

[phaustin]

On current master, if I create a conda environment with"

conda create -n  testpoetry python=3.7 poetry
conda activate testpoetry
poetry install

I get the this error:

% poetry install
Creating virtualenv trio-chrome-devtools-protocol-tfpj-LfL-py3.7 in /Users/phil/Library/Caches/pypoetry/virtualenvs
Installing dependencies from lock file
Warning: The lock file is not up to date with the latest changes in pyproject.toml. You may be getting outdated dependencies. Run update to update them.

[SolverProblemError]
Because trio-chrome-devtools-protocol depends on chrome-devtools-protocol (^0.4.0) which doesn't match any versions, version solving failed.

If I edit pyproject.toml:

 [tool.poetry.dependencies]
 python = "^3.7"
-chrome-devtools-protocol = "^0.4.0"
+chrome-devtools-protocol = "^0.3.0"
 trio = "^0.13.0"
 trio_websocket = "^0.8.0"

the install succeeds and tests pass.

confirming this works with conda

poetry update
poetry install
