Node error spawn unknown

I have a similar problem when running unit tests with jest and the mongodb-memory-server package (https://github.com/nodkz/mongodb-memory-server).

When running a sample script starting the server (binaries fully downloaded, no local mongod instance running locally), I get a similar error like in the issue desription.

Node.js version
v16.15.1

package.json
{ "devDependencies": { "nodemon": "^2.0.18", "ts-node": "^10.8.2", "typescript": "^4.7.4" }, "dependencies": { "mongodb-memory-server": "^8.7.2" }, "config": { "mongodbMemoryServer": { "debug": "1" } } }

Example code

import { MongoMemoryServer } from 'mongodb-memory-server';

(async () => {
    const mongod = await MongoMemoryServer.create();
    const uri = mongod.getUri();
    console.log('uri: ', uri);
    await mongod.stop();
})();

Log output

It looks like the child process failed to spawn an application. Can you provide some more context, that gives some more information?

UnhandledPromiseRejectionWarning: Error: spawn UNKNOWN #6495

Tried to search for this error but couldn’t find any open issue. Some users are still running an old version of our app because the updater fails to verify the signature. Checking into Sentry I found the following error:

Please let me know if there is anything missing to investigate this further. Thanks!

I’ve got the same issue running with :

Expected Behavior

I updated Electrons to have the latest fixes and thought all of them are working fine.

Now none of the Electron related commands are working.

Actual Behavior

I just updated electron from version ^ 13.1.8″ to «^14.0.1» and since then I can’t run any Electron-related commands.

I get the following error:

Do you have any idea where it might come from? I have node v16.9.1

Error Description:

We get the following error:

events.js:72
throw er; // Unhandled 'error' event
              ^
Error: spawn ENOENT
    at errnoException (child_process.js:1000:11)
    at Process.ChildProcess._handle.onexit (child_process.js:791:34) 

Solution 1:

Error: spawn ENOENT 

The problem of this error is, there is really little information in the error message to tell you where the call site is, i.e. which executable/command is not found, especially when you have a large code base where there are a lot of spawn calls.

(function(){
var childProcess = require("child_process");
var oldSpawn = childProcess.spawn;
function mySpawn(){
        console.log('spawn called');
        console.log(arguments);
var result = oldSpawn.apply(this, arguments);
return result;
}
    childProcess.spawn = mySpawn;
})(); 

Then the next time you run your application, before the uncaught exception’s message you will see something like that:

spawn called
{'0':'hg',
'1':[],
'2':
{ cwd:'/* omitted */',
     env:{ IP:'0.0.0.0'},
     args:[]}} 

Solution 2:

Ensure spawn is called the right way

First, review the docs for child_process.spawn( command, args, options ):

Solution 3:

Identify the Event Emitter that emits the error event

spawn('some-command',['--help']);
 

and attach there an event listener for the ‘error’ event, so you get noticed the exact Event Emitter that is throwing it as ‘Unhandled’. After debugging, that handler can be removed.

spawn('some-command',['--help'])
.on('error',function( err ){throw err })
; 

Execute and you should get the file path and line number where your ‘error’ listener was registered. Something like:

/file/that/registers/the/error/listener.js:29
      throw err;
            ^
Error: spawn ENOENT
    at errnoException (child_process.js:1000:11)
    at Process.ChildProcess._handle.onexit (child_process.js:791:34) 

events.js:72
        throw er; // Unhandled 'error' event 

Solution 4:

Ensure the environment variable $PATH is set

There are two possible scenarios:

In both scenarios, you must inspect the PATH key on the environment object that the spawned child process will use.

Example for scenario 1

// inspect the PATH key on process.env
console.log( process.env.PATH );
spawn('some-command',['--help']); 

Example for scenario 2

var env = getEnvKeyValuePairsSomeHow();
// inspect the PATH key on the env object
console.log( env.PATH );
spawn('some-command',['--help'],{ env: env }); 

The absence of PATH (i.e., it’s undefined) will cause spawn to emit the ENOENT error, as it will not be possible to locate any command unless it’s an absolute path to the executable file.

Solution 5:

Ensure command exists on a directory of those defined in PATH

Spawn may emit the ENOENT error if the filename command (i.e, ‘some-command’) does not exist in at least one of the directories defined on PATH.

Locate the exact place of command. On most linux distributions, this can be done from a terminal with the which command. It will tell you the absolute path to the executable file (like above), or tell if it’s not found.

Example usage of which and its output when a command is found

> which some-command
some-command is /usr/bin/some-command 

Example usage of which and its output when a command is not found

> which some-command
bash: type: some-command: not found
