bun pm cache failed: ${cacheResult.stderr}

Error message

bun pm cache failed: ${cacheResult.stderr}

What it means

refreshBunGitCache runs `bun pm cache` in the given cwd before a plugin git update so Bun's cached bare clone is fresh. If the command exits non-zero it throws with the captured stderr. This is the pre-update cache bootstrap for git-hosted plugin installs.

Solutions

1. Run `bun pm cache` manually in the same directory to see the real error.
2. Ensure bun is installed and on PATH (`which bun`; check version — `bun pm cache` needs a recent bun).
3. Upgrade bun (`bun upgrade`) if the subcommand is missing.
4. Fix permissions/home dir issues that prevent bun from accessing its cache.

Example fix

// verify before installing
$ bun pm cache
/Users/you/.bun/install/cache  # must succeed and print a path

const proc = Bun.spawn(["bun", "pm", "cache"], { stdout: "pipe", stderr: "pipe" });
const [code, out] = await Promise.all([proc.exited, new Response(proc.stdout).text()]);
if (code !== 0 || !out.trim()) throw new Error("bun pm cache unavailable");
// only then call installPlugin/updatePlugin

function isBunAvailable(): boolean {
  const which = Bun.which("bun");
  return typeof which === "string" && which.length > 0;
}

try {
  await updateGitPlugin(source, cwd);
} catch (err) {
  if (err instanceof Error && err.message.startsWith("bun pm cache failed:")) {
    logger.warn("Skipping bun cache refresh", { stderr: err.message });
    // proceed without refresh or abort install deliberately
  } else throw err;
}

When it happens

Trigger: Installing/updating a git-sourced plugin when `bun pm cache` fails — bun not on PATH, broken bun installation, or the command erroring in the plugin's cwd.

Common situations: bun not installed or an old bun version lacking `pm cache`; restricted environment/CI where bun cannot write its cache dir; PATH differences between shell and the process spawning the installer.
