Could not resolve {label} path {raw_path!r}: {exc}. Ensure t

Error message

Could not resolve {label} path {raw_path!r}: {exc}. Ensure the path exists and is accessible.

What it means

_normalize_path calls Path(raw_path).expanduser().resolve(), and if the OS raises OSError (e.g. permission denied, I/O error, too many symlinks, or an unresolvable path on some platforms) the error is re-raised as a ValueError with a clear, label-aware message pointing at which path failed.

    Returns:
        Absolute path string, or `None` when *raw_path* is `None` or empty.

        ValueError: If the path cannot be resolved.

Solutions

1. Verify the path exists and is accessible: run `ls -ld <path>` (and each parent) as the same user the CLI runs as.
2. Fix permissions or mount state for the failing directory, or correct the typo in the path.
3. If the path may legitimately be absent, check `Path(p).exists() and os.access(p, os.R_OK)` before invoking the CLI and supply a valid path.
4. Set HOME explicitly if '~' expansion is involved and HOME is wrong or unset.

Example fix

# before
deepagents-code --workdir /mnt/share/project   # share unmounted
# after
mount /mnt/share  # or point --workdir at an accessible local path

When it happens

Trigger: Passing a path via CLI args (from_cli_args -> _normalize_path) for which expanduser().resolve() hits an OSError — e.g. a directory with no execute permission, a broken symlink chain, or a path on an unreadable/unmounted filesystem.

Common situations: Running the CLI against a mounted network share that is offline; using '~' with an unset HOME causing issues; chmod'ing down a parent directory; mistyped path with unusual characters on certain filesystems.
