how do you run it in you node application?
from lambda-clamav-layer.
This appears to happen when you run the command with child_process.exec, but not childProcess.spawn
// doesn't work
fs.writeFileSync('/tmp/bs.txt', 'hello world!', { encoding: 'utf8' })
const file = fs.readFileSync('/tmp/bs.txt', 'utf8')
console.log('file contents', file)
const scan = execSync('clamscan /tmp/bs.txt')
console.log('scan status', scan.status);
console.log(scan.stdout.toString());
produces:
{
"errorType": "Error",
"errorMessage": "Command failed: clamscan /tmp/bs.txt\nLibClamAV Error: cl_load(): No such file or directory: /var/clamav\nERROR: Can't get file status\n",
"trace": [
"Error: Command failed: clamscan /tmp/bs.txt",
"LibClamAV Error: cl_load(): No such file or directory: /var/clamav",
"ERROR: Can't get file status",
"",
" at checkExecSyncError (child_process.js:616:11)",
" at execSync (child_process.js:652:15)",
" at Runtime.exports.handler (/var/task/index.js:10:18)",
" at Runtime.handleOnce (/var/runtime/Runtime.js:66:25)"
]
}
// works kinda
const spawnSync = require('child_process').spawnSync;
fs.writeFileSync('/tmp/bs.txt', "hello world!", { encoding: 'utf8' })
const file = fs.readFileSync('/tmp/bs.txt', 'utf8')
console.log('file contents:', file)
const scan = spawnSync('clamscan', ['', '/tmp/bs.txt'], {
stdio: 'pipe',
stderr: 'pipe'
});
console.log('scan status', scan.status);
console.log(scan.stdout.toString());
produces:

Hi all,
Implement the same approach as m-schrepel but still got "No such file or directory"
//My codes
