pdm export doesn't provide the a hint to the culprit if an editable requirement in pyproject.toml is misspelled.

[arturloewen]

As stated in the title, calling 'pdm export' doesn't provide the a hint to the culprit (file and line or dependency) if an editable requirement in pyproject.toml is misspelled. One is left to wonder, what the actual problem is.

• I have searched the issue tracker and believe that this is not a duplicate.

Steps to reproduce

Add the following to pyproject.toml:
[tool.pdm.dev-dependencies]
dev = [
"-e file:///${PROJECT_ROOT}/<misspelled_folder>"
]
pdm export --without-hashes --output requirements.txt -vv

Actual behavior

The call above will result in the following error message and stop without producing the output file:
[RequirementError]: Editable requirement is only supported for VCS link or local directory.

Expected behavior

I would expect the error message to provide me hint to which file and line or which dependency caused the error.
