Error spawn python enoent

Encountering ‘spawn python ENOENT’ error while running discover tests on VSCode

What’s the best approach to tackle this specific issue? I’ve attempted several methods such as using npm init, npm install, experimenting with code placement and directory, as well as searching online for solutions. However, I still can’t seem to find a fix. On a positive note, someone with a similar issue recommended adding ‘pythonPath: ‘python» which resolved their problem. Alternatively, there is another solution.

VSCode on discover tests Error: spawn python ENOENT

In Visual Studio Code, I am executing a python project using virtualenv and have correctly set up the Python interpreter. However, while attempting to locate tests, an error message is displayed.

python /Users/user/.vscode/extensions/ms-python.python-2019.10.44104/pythonFiles/testing_tools/run_adapter.py discover pytest -- -s project/ Test Discovery failed: Error: spawn /Users//apps/project/venv/bin/python ENOENT 

My settings.json in vscode is configured, but I have not yet set up launch.json.

< "python.pythonPath": "/Users//apps/project/venv/bin/python", "python.testing.unittestEnabled": false, "python.testing.nosetestsEnabled": false, "python.testing.pytestEnabled": true, "python.testing.pytestArgs": [ "project" ], > 

Upon typing the code /Users//apps/project/venv/bin/python in the terminal, the Python shell opens up.

Typically, ENOENT indicates that the path is invalid, although it appears to be correct.

$echo $PATH /Users//apps/project/venv/bin 

Upon encountering a familiar problem, I discovered that it occurred because I had utilized a wrong variable, workspaceDir , instead of the correct one workspaceFolder , in the setting for a folder that did not exist.

It appears that restarting VSCode is necessary for any changes made here to take effect. Therefore, even if you mistakenly change it to an incorrect value, it may still appear to be working until you restart, at which point you will encounter ENOENT. The same holds true in reverse.

After deleting the local .vscode folder within the project and saving the workspace, I created a new .vscode/settings.json file that included the testing settings. This solution fixed the issue.

The origin of the information is found at the following GitHub link: https://github.com/microsoft/vscode-python/issues/5316.

My problem was resolved after incorporating «python.testing.cwd»: «$» into settings.json .

Although I’m uncertain of the specific problem, I completely removed vscode from my laptop. After reinstalling it from the beginning, it functioned properly.

How do I debug «Error: spawn ENOENT» on node.js?, Step 1: Ensure spawn is called the right way. First, review the docs for child_process.spawn ( command, args, options ): Launches a new process with the given command, with command line arguments in args. If omitted, args defaults to an empty Array.

Spawn python ENOENT node.js in windows

I developed a code for my brother who required to utilize a python function from his backend node.js. Although the code works on my Ubuntu computer, it produces a stacktrace when executed on his Windows machine.

events.js:174 throw er; // Unhandled 'error' event ^ Error: spawn python ENOENT at Process.ChildProcess._handle.onexit (internal/child_process.js:240:19) at onErrorNT (internal/child_process.js:415:16) at process._tickCallback (internal/process/next_tick.js:63:19) at Function.Module.runMain (internal/modules/cjs/loader.js:757:11) at startup (internal/bootstrap/node.js:283:19) at bootstrapNodeJSCore (internal/bootstrap/node.js:622:3) Emitted 'error' event at: at Process.ChildProcess._handle.onexit (internal/child_process.js:246:12) at onErrorNT (internal/child_process.js:415:16) [. lines matching original stack trace . ] at bootstrapNodeJSCore (internal/bootstrap/node.js:622:3) 

const spawn = require("child_process").spawn; const pythonProcess = exec('python',["./script.py", 2, 4]); pythonProcess.stdout.on('data', function(data) < console.log(data.toString('utf-8')) >) 

and this is the script.py file

import sys print("work with me please") sys.stdout.flush() 

Many individuals face similar problems, but the solutions provided appear to be too specific to their needs. Certain solutions involve PATH variable, while others involve npm.cmd or another alternative.

How should I work around this particular case?

Various attempts have been made to solve the problem, including running npm init, npm install, experimenting with moving code components, conducting web searches, and modifying the cmd and directory scopes.

I faced a similar issue and found a solution by adding the following line in my code: pythonPath: ‘python’

const < PythonShell >= require('python-shell'); let options = < mode: 'text', pythonPath: 'python', pythonOptions: ['-u'], // get print results in real-time scriptPath: 'path', args: ['arg1', 'arg2'] >; PythonShell.run('scraper.py', options, function(err, results) < if (err) console.log(err); // results is an array consisting of messages collected during execution console.log('results: %j', results); >); 

The code on line 292, specifically the «throw er» statement, is triggered by an event that is represented by «Unhandled ‘error».

The code encountered an error in the child process while handling the exit event. The error was emitted by the ChildProcess instance, with details including the errno, code, syscall, path, and spawnargs. The error occurred at line 267:19 in internal/child_process.js and was also caught at line 273:12. Additionally, the error was handled by the onErrorNT function at line 469:16 and the processTicksAndRejections function at line 84:21 in internal/process/task_queues.js.

This script, which has been adapted from a source on Medium, enables running python-script from both node-js and send-data on a browser.

I change ‘python’ in ‘python3’ on

The variable python = spawn stores the command ‘python3’ along with the file path of ‘script2.py’.

const express = require('express') const = require('child_process'); const app = express() const port = 3000 app.get('/', (req, res) => < var dataToSend; // spawn new child process to call the python script const python = spawn('python', [__dirname +'/script2.py']); // collect data from script python.stdout.on('data', function (data) < console.log('Pipe data from python script . '); dataToSend = data.toString(); >); // in close event we are sure that stream from child process is closed python.on('close', (code) => < console.log(`child process close all stdio with code $`); // send data to browser res.send(dataToSend) >); >) app.listen(port, () => console.log(`Example app listening on port $!`))

let = require('python-shell') PythonShell.run('test.py', function (err, results) < if (err) throw err; console.log('test.py finished.'); console.log('results', results); >);
