在 Nodejs 中使用 PythonShell 模块 [英] Using PythonShell module in Nodejs

问题描述

我一直在尝试遵循 npm pythonshell 此处的文档.我只是想得到一个简单的例子来正常运行但没有成功，网上的例子并不多，但我确实尝试遵循这个 stackoverflow 上的一个.那么我的代码到底有什么问题呢?我不确定为什么会收到以下错误.我在 python 中更舒服，nodejs 对我来说是新领域.感谢您的帮助.

I have been trying to follow the documentation for the npm pythonshell here. I'm just trying to get a simple example to function correctly with no success, not many examples online but I did try to follow this one on stackoverflow. So what exactly is wrong with my code here? I'm not really sure why I'm getting the below error. I'm far more comfortable in python, nodejs is new territory for me. Thank you for any help.

test.py 代码:

print("This is a test")

Nodejs 与 pythonshell 测试:

var PythonShell = require('python-shell');

    var options = {
      mode: 'text',
      pythonPath: '/bin/bash/python2', 
      pythonOptions: ['-u'],
      scriptPath: './TestProject/',
      args: ['value1', 'value2', 'value3']
    };

    PythonShell.run('test.py', options, function (err, results) {
      if (err) throw err;
      // results is an array consisting of messages collected during execution
      console.log('results: %j', results);
    });

这是我的错误

    internal/child_process.js:313
    throw errnoException(err, 'spawn');
    ^

推荐答案

所以我犯了一个错误，没有在新系统安装中检查我的 python 路径，但是使用绝对路径也是脚本正常运行的必要条件.这是任何尝试使用 nodejs python-shell npm 运行 python 脚本的人的工作示例.感谢 Bryan 帮助我解决 javascript 错误.

So I made the mistake of not checking my python path on a new system install, however using an absolute path is also nessasary for the script to function. Here is a working example for anyone trying to run python scripts using nodejs python-shell npm. Thanks to Bryan for helping me with javascript error.

var PythonShell = require('python-shell');

    var options = {
      mode: 'text',
      pythonPath: '/usr/bin/python', 
      pythonOptions: ['-u'],
      // make sure you use an absolute path for scriptPath
      scriptPath: '/home/username/Test_Project/Python_Script_dir',
      args: ['value1', 'value2', 'value3']
    };

    PythonShell.run('test.py', options, function (err, results) {
      if (err) throw err;
      // results is an array consisting of messages collected during execution
      console.log('results: %j', results);
    });
