poetry run tox FileNotFoundError

While running poetry run tox I encountered the vague error FileNotFoundError

poetry run tox                                                           1:38:03

  FileNotFoundError

  [Errno 2] No such file or directory: b'/sbin\n\nsource /Users/willcasswrig/.poetry/env/tox'

       610│         except OSError as e:
       611│             last_exc = e

Note: adding -vvv verbose flag didn't help

Solution

  • Since tox was listed under the [tool.poetry.dev-dependencies] section of my pyproject.toml file, it wasn't automatically added.

    Either run poetry add tox or move from dev-dependencies section into [tool.poetry.dependencies]
