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"); }); 

ERROR :

cmd:"C:\WINDOWS\system32\cmd.exe /s /c "code c:\Users\shana\Dropbox\code-settings-syn... (length: 82)" code:1 killed:false message:"Command failed: C:\WINDOWS\system32\cmd.exe /s /c "code c:\Users\shana\Dropbox\c... (length: 99)" signal:null stack:undefined 

Detail of error JSON.

Full CMD : "C:\WINDOWS\system32\cmd.exe /s /c "code c:\Users\shana\Dropbox\code-settings-sync"" Full message : "Command failed: C:\WINDOWS\system32\cmd.exe /s /c "code c:\Users\shana\Dropbox\code-settings-sync"\n"

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??

the problem is that it works 1,2 times this example and my example after that same error popups
verify the string you are passing to exec command or storing in array . is it properly escaped in terms of your os
yes you can check the full CMD in the code i have shown and its working fine in Windows when i write in command prompt.

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
