在Node.js中判定文件是否可执行的方法详解

npm install isexe

import { isexe } from 'isexe';

isexe('some-file-name').then(isExe => {
  if (isExe) {
    console.log('this thing can be run');
  } else {
    console.log('cannot be run');
  }
}).catch(err => {
  console.log('probably file doesnt exist or something', err);
});

import { sync } from 'isexe';

try {
  const isExe = sync('some-file-name');
  if (isExe) {
    console.log('this thing can be run');
  } else {
    console.log('cannot be run');
  }
} catch (err) {
  console.log('probably file doesnt exist or something', err);
}

import { isexe, sync } from 'isexe';

// Async with ignoreErrors
isexe('maybe-missing-file', { ignoreErrors: true }).then(isExe => {
  console.log(isExe ? 'Executable' : 'Not executable or missing');
});

// Sync with ignoreErrors
try {
  const isExe = sync('maybe-missing-file', { ignoreErrors: true });
  console.log(isExe ? 'Executable' : 'Not executable or missing');
} catch (err) {
  // There will be no error thrown due to ignoreErrors option
}

import { win32 } from 'isexe';

win32.isexe('some-file-name').then(isExe => {
  // your code here
});

import { isexe } from 'isexe';

isexe('some-file-name', {
  uid: process.getuid(),
  gid: process.getgid(),
  pathExt: ['.EXE', '.CMD', '.BAT']  // Just for Windows
}).then(isExe => {
  // Executable check with custom options
});
