walk-sync Error: EBUSY: resource busy or locked?

Question

报错的代码:

function walk(filePath) {
    const states = statSync(filePath)
    // ...
}
readdirSync("d:\\").forEach(walk)

报错信息:

Error occurred in handler for 'walk-sync': Error: EBUSY: resource busy or locked, stat 'd:\pagefile.sys'
    at statSync (node:fs:1615:3)
    at t.statSync (node:electron/js2c/asar_bundle:2:4510)
    at walk (E:\...\dist-electron\main\index.js:248:28)

  errno: -4082,
  syscall: 'stat',
  code: 'EBUSY',
  path: 'd:\\pagefile.sys'
}

pagefile.sys应该是分页文件吧？请问这个怎么办呢？
谢谢。

我尝试忽略出错的文件:

let states
try {
    states = statSync(filePath)
} catch (error) {
    return
}

然后直接弹出错误窗口了:

[Window Title]
Error

[Main Instruction]
A JavaScript error occurred in the main process

[Content]
Uncaught Exception:
Error: EBUSY: resource busy or locked, lstat 'd:\pagefile.sys'

[确定]

这么写try catch有问题吗？为什么还是报错？

Answer 1

这个应该和那你的try catch 写法没关系，报错信息已经说了 EBUSY: resource busy or locked, stat 'd:\pagefile.sys'，大概是这个文件 d:\pagefile.sys 被什么占用了，然后你又去读它，看下是不是有什么程序正在操作或者打开你这个文件。

Answer 2

function walk(filePath) {
    if (filePath.endsWith('pagefile.sys')) {
        return; // 跳过pagefile.sys
    }
    let states;
    try {
        states = statSync(filePath);
    } catch (error) {
        console.error(`无法访问文件 ${filePath}: ${error.message}`);
        return;
    }
    // ...
}
