Making a virtualenv in the project root fails if <cache-dir>/virtualenvs does not exist #1573
Description
- 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 (
-vvvoption).
- OS version and name: macOS Catalina (10.15.1)
- Poetry version: 1.0.0b3
- Link of a Gist with the contents of your pyproject.toml file: N/A
Issue
It appears that if poetry has never made a virtualenv for you—which means that <cache-dir>/virtualenvs does not exist, then asking poetry to make a virtualenv in the project root will fail.
$ poetry env use python3 -vvv 11:12:03
