Node Child Process Exec Command Failed with error code 1
Solution 1
try a simpler example ..
var exec = require('child_process').exec;
var cmd = 'code C:\Program Files';
exec(cmd, function(err, stdout, stderr) {
if (err) {
console.error(err);
return;
}
console.log(stdout);
});
does this work??
Solution 2
I didn't want to see the whole error (too verbose) so I did something like this:
try {
const { stdout, stderr } = await exec('echo TEST');
console.log('stdout:', stdout);
console.log('stderr:', stderr);
} catch (e) {
// If exec fails and you want to see the whole ugly error:
// console.error(e);
console.log('How about a nice human readable message instead?');
}
Because of the "await" this goes inside an "async" function. More information: https://stackoverflow.com/a/56095793/722796

I am trying to execute some line using node js child process and getting error. Following is my code:
let cmd : string = "code " + PROJECTS[value]; exec(cmd, function callback(error, stdout, stderr) { console.log("started console app"); });

Nabeel Hassan over 8 yearsverify the string you are passing to exec command or storing in array . is it properly escaped in terms of your os
