创建存储目录失败

Error message

创建存储目录失败: %v

What it means

During weibo plugin Initialize, the storage directory for cached weibo user data (cachePath/weibo_users) is created with os.MkdirAll. If directory creation fails (permission denied, read-only filesystem, path is a file), Initialize returns '创建存储目录失败' (failed to create storage directory) and the plugin fails to start.

Solutions

  1. Set the cachePath config/env to a writable directory (e.g. /tmp or a mounted volume)
  2. Ensure the process user owns or can write the cachePath parent
  3. Remove any regular file that occupies the cachePath
  4. Mount a writable volume in containers and point StorageDir there
  5. Check disk space / read-only mount status

Example fix

// before
if err := os.MkdirAll(StorageDir, 0755); err != nil {
    return fmt.Errorf("创建存储目录失败: %v", err)
}
// after
if err := os.MkdirAll(StorageDir, 0755); err != nil {
    return fmt.Errorf("创建存储目录失败 %s: %w", StorageDir, err)
}
// deploy side: docker run -v weibo_cache:/data/cache -e CACHE_PATH=/data/cache ...
Defensive patterns

Strategy: try-catch

Validate before calling

cacheDir := filepath.Join(cachePath, "weibo_users")
if err := os.MkdirAll(cacheDir, 0755); err != nil {
    return fmt.Errorf("cache dir not writable %s: %w", cacheDir, err)
}
// run this probe (or a writable-file test) before Initialize

Try / catch

if err := weiboPlugin.Initialize(cfg); err != nil {
    if strings.Contains(err.Error(), "创建存储目录失败") {
        cfg["cachePath"] = os.TempDir() // retry with a writable dir
        err = weiboPlugin.Initialize(cfg)
    }
    if err != nil { return err }
}

Prevention

When it happens

Trigger: Calling Initialize when cachePath resolves to a location the process cannot write (e.g. /cache root-owned in a container), the path exists as a regular file, or the disk is read-only/full.

Common situations: Docker container running as non-root with default ./cache under a root-owned volume; cachePath env/config pointing at a system path without permissions; a file named 'cache' blocking directory creation; read-only root filesystem with no writable volume mounted.
