Install error when installing a non-package in package-mode gives invalid instructions #9072
Description
Description
Create an empty project with poetry init, then attempt to install it. Without the README.md file being created, the installation will fail. When installation fails without configuring package-mode, Poetry 1.8.1 emits the following error message:
Warning: The current project could not be installed: [Errno 2] No such file or directory: '/README.md'
If you do not want to install the current project use --no-root.
If you want to use Poetry only for dependency management but not for packaging, you can set the operating mode to "non-package" in your pyproject.toml file.
In a future version of Poetry this warning will become an error!
The message instructs to 'set the operating mode to "non-package" in your pyproject.toml file', implying using 'non-package = true' or similar, whereas the correct key is 'package-mode = false'.
Workarounds
The correct key can be inferred from a search.
