Javascript 解释node.js概要文件输出？

test.js

输出：

node --prof test.js
nprof

---

我希望它在[JavaScript]部分显示“test”函数。为什么它不在那里？

nprof对v8.log格式使用了不同于现有格式的tick处理器

我在中也有相同的功能（目前与node 0.8.2 afaik兼容）

可能的解决办法：

• 试一试
• 请尝试以前版本的nprof（

  npm安装profiler@1.2.0

  ）

或者，您可以尝试使用节点版本中的脚本重建nprof：

node的哪个版本？使用0.8.2（例如），我使用您的程序并获得预期的输出，与我在您的帖子中看到的完全不同。我的输出在这里：@Joe，0.8.2，我刚刚在OSX上构建。奇怪的
