+在有些场景，我们需要创建一个临时目录，那么这时我们可以使用 `fs.mkdtempSync(pathPrefix, options?)`，它会在 `pathPrefix` 目录下创建一个随机6位字符串作为名称的目录，并返回路径
+
+如果我们需要在系统的全局临时目录中创建临时目录，我们可以借助 `os.tmpdir()`
+
+```typescript
+import * as os from "node:os";
+import * as fs from "node:fs";
+import * as path from "node:path";
+
+const pathPrefix = path.resolve(os.tmpdir(), "my-app");
+const tmpPath = fs.mkdtempSync(pathPrefix);
