从Node.js运行Python脚本——获取导入错误：没有名为google.cloud的模块

我正在尝试从Node.js调用python脚本。它正在执行python脚本，但在脚本中给出错误，如

ImportError:no module name google.cloud

my Node.js包含以下代码：

/**
 *  * Background Cloud Function to be triggered by Cloud Storage.
 *   *
 *    * @param {object} event The Cloud Functions event.
 *     * @param {function} callback The callback function.
 *      */
exports.hellogcspy1 = function (event, callback) {
var PythonShell = require('python-shell');


var options = {
  mode: 'text',
  pythonPath: '/usr/bin/python2.7',
  pythonOptions: ['-u'],
  scriptPath: '.',
  args: ['value1', 'value2', 'value3']
};
PythonShell.run('my_script.py', options, function (err, results) {
  if (err) throw err;
  console.log('results: %j', results);
});
};

{
  "name": "python-shell",
  "version": "0.4.0",
  "description": "to test python run",
  "main": "Node.js",
  "scripts": {
    "test": "python my_script.py"
  },
  "keywords": [
    "python"
  ],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "python-shell": "^0.4.0"
  },
  "repository": {},
  "devDependencies": {}
} 

python脚本名为my_script.py。当我从创建pythonshell和package.json的目录运行这个脚本时，我没有得到任何导入错误。 Package.json包含以下代码：

/**
 *  * Background Cloud Function to be triggered by Cloud Storage.
 *   *
 *    * @param {object} event The Cloud Functions event.
 *     * @param {function} callback The callback function.
 *      */
exports.hellogcspy1 = function (event, callback) {
var PythonShell = require('python-shell');


var options = {
  mode: 'text',
  pythonPath: '/usr/bin/python2.7',
  pythonOptions: ['-u'],
  scriptPath: '.',
  args: ['value1', 'value2', 'value3']
};
PythonShell.run('my_script.py', options, function (err, results) {
  if (err) throw err;
  console.log('results: %j', results);
});
};

{
  "name": "python-shell",
  "version": "0.4.0",
  "description": "to test python run",
  "main": "Node.js",
  "scripts": {
    "test": "python my_script.py"
  },
  "keywords": [

  "dependencies": {
    "python-shell": "^0.4.0"
  },
  "repository": {},
  "devDependencies": {}
} 

my_script.py包含谷歌云模块的导入，即

from google.cloud import storage,from google.cloud import bigquery
from google.cloud.bigquery import SchemaField

它在VM上运行正常，但在Node.js上运行不正常。有人能告诉我为什么从Node.js执行时出现错误

ImportError:no module name google.cloud

？尝试版本google cloud==0.27.0，之前的版本有一些不一致的依赖项您建议安装此版本的google cloud吗？我运行$pip show google cloud并得到以下结果：pip show google cloud名称：google cloud版本：0.27.0摘要：google cloud的API客户端库主页：作者：google cloud平台作者电子邮件：googleapis-publisher@google.com许可证：Apache2.0位置：/usr/lib64/python2.7/site-packages要求：谷歌云翻译，谷歌云资源管理器，谷歌云dns，谷歌云bigquery。。。。。。。看起来它只是最新版本。当您从创建python shell和package.json的目录运行脚本时，你使用python 2.7还是3.x？它是python2.7，因为当我运行脚本时，它会进入路径/usr/lib/python2.7/site packages/google/cloud/storage…当你打开

/usr/bin/python2.7

的实时解释器并尝试

导入google.cloud

时会发生什么？
