node.js process.memoryUsage() ENOENT

Question

I just want to execute

console.log(process.memoryUsage())

in test.js with

node test.js

In my localhost it works perfectly, but on my server it generates the following error:

console.log(process.memoryUsage())
                ^
Error: ENOENT, no such file or directory
at Error (native)

at Function.Module.runMain (module.js:501:10)
at startup (node.js:129:16)

I'm using node v0.12.2. Any ideas why this error occurs?

正如我在评论中提到的，它可能是因为os中的用户权限而发生的。
