python - 无法将 Python 客户端连接到 Azure Cosmo Bd : Import pydocumentdb fails

Question

我在安装了内置 Python 2.7 的 Mac 上工作

我使用 sudo easy_install pip 安装了 pip

我使用 sudo pip install azure 安装了 azure

现在我为 azure 编写了一个简单的 python 客户端:

import pydocumentdb
from pydocumentdb import errors
from pydocumentdb import documents
from pydocumentdb import document_client

import config as cfg

HOST = cfg.settings['host']
MASTER_KEY = cfg.settings['master_key']
DATABASE_ID = cfg.settings['database_id']
COLLECTION_ID = cfg.settings['collection_id']

database_link = 'dbs/' + DATABASE_ID

@staticmethod
def list_collections(client):
        print("\n5. List all Collection in a Database")

        print('Collections:')

        collections = list(client.ReadCollections(database_link))

        if not collections:
            return

        for collection in collections:
            print(collection['id'])

def run_sample():

    with IDisposable(document_client.DocumentClient(HOST, {'masterKey': MASTER_KEY} )) as client:
        try:
            # list all collection on an account
            list_collections(client)  
        except errors.HTTPFailure as e:
            print('\nrun_sample has caught an error. {0}'.format(e.message))

        finally:
            print("\nrun_sample done")

if __name__ == '__main__':
    try:
        run_sample()

    except Exception as e:
            print("Top level Error: args:{0}, message:{1}".format(e.args,e.message)) 

然后当我运行程序时出现错误

Traceback (most recent call last): File "ReadDatabase.py", line 1, in import pydocumentdb ImportError: No module named pydocumentdb

所以我读到了两个原因:Azure 未安装或 Sys.path 有问题

我做了一个示例来显示 sys.path

import sys

if __name__ == '__main__':
    print sys.path

给我结果:

所以我没有看到 Azure 库。

事实上，我认为 pydocumentdb 是 Azure Python SDK 的一部分，但事实并非如此执行 pip install pydocumentdb 解决了问题
