Issue

On poetry version 1.0.4, whenever command poetry build is executed, error is produced:
[FileNotFoundError] [Errno 2] No such file or directory: 'git'
It happens in docker-container python:3.8-slim

On Poetry version 1.0.3 workflow works as expected.

Please see the log output:

+ poetry -V
Poetry version 1.0.4
+ poetry build -vvv
Skipping virtualenv creation, as specified in config file.
