o yt-dlp não está disponível

Error message

o yt-dlp não está disponível: {}

What it means

run_ytdlp first calls ensure_ytdlp(), which locates or downloads the yt-dlp binary; if that fails (binary missing, download failed, unsupported platform), the error is wrapped as "o yt-dlp não está disponível". The download run aborts before any yt-dlp invocation because the tool is a hard dependency.

Solutions

1. Install yt-dlp manually (pip install yt-dlp) and put it on PATH
2. Ensure network access so ensure_ytdlp can auto-download the binary
3. Check that the app's tools/data directory is writable
4. Read the wrapped inner error for the precise cause (download vs exec failure)

Example fix

// before: relying on auto-download
// after: verify availability up front
if which::which("yt-dlp").is_err() {
    eprintln!("instale o yt-dlp: pip install yt-dlp");
    return;
}

if which::which("yt-dlp").is_err()
    && !std::path::Path::new("tools/yt-dlp").exists() {
    eprintln!("instale yt-dlp antes de baixar: pip install yt-dlp");
}

When it happens

Trigger: Calling the reddit download run flow when yt-dlp is neither on PATH nor in the app's tools directory and ensure_ytdlp cannot fetch it — no network to download it, unsupported architecture, or blocked filesystem write.

Common situations: Fresh install without yt-dlp, offline/air-gapped environment preventing the auto-download, PATH not including the app's bin dir, antivirus removing the downloaded binary.

Understand the failure class

Background: "not installed", "pip install", "required for": how missing-dependency errors surface across open-source libraries — this error's family across 34 libraries.
