Can’t install dependencies in docker container

I’m using poetry library to manage project dependencies, so when I use

docker build --tag=helloworld .

I got this error

[AttributeError]               
'NoneType' object has no attribute 'group'  

Installing breaks on umongo (2.1.0) package

Here is my pyproject.toml file

[tool.poetry.dependencies]
python = "^3.7.0"
asyncio = "^3.4"
aiohttp = "^3.4"
motor = "^2.0"
umongo = "^2.0"
pyyaml = "^3.13"

[tool.poetry.dev-dependencies]
pytest = "^3.4"
black = {version = "^18.3-alpha.0",allows-prereleases = true}
mypy = "^0.650.0"
wemake-python-styleguide = "^0.5.1"
pytest-mock = "^1.10"
pytest-asyncio = "^0.9.0"
pytest-aiohttp = "^0.3.0"
