python - 部署云函数时index.js出错

Question

我正在尝试使用 Cloud Function 事件触发器执行 python 脚本。我的index.js有以下代码:

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

PythonShell.run('my_script.py', function (err) {
  if (err) throw err;
  console.log('finished');
});

exports.processFile = function(event, callback) {
  console.log('Processing file: ' + event.data.name);
  callback();
};

module.exports = PythonShell;

package.json 有以下代码:

{ 
   "name": "python-shell", 
   "version": "0.4.0", 
   "description": "Run Python scripts from Node.js with simple (but efficient) inter-process communication through stdio", 
   "keywords": [ 
   "python" 
    ], 
   "scripts": { 
    "test": "my_script.py" 
   },
   "dependencies" : {}
}

但是该函数尚未创建。它显示以下错误:错误:

Deployment failure:
Function load error: Code in file index.js can't be loaded.
Did you list all required modules in the package.json dependencies?

请问如何解决？
