Python中的Google Cloud Function在部署时出错

Question

我正在尝试将 Google Cloud Functions 配置为在触发该功能时下订单。 我在requirements.txt 文件中提到了kiteconnect 但是该功能没有被部署。引发错误“未知资源类型”。

完整的错误消息：

Deployment failure: Build failed: {"error": {"canonicalCode": "INVALID_ARGUMENT", "errorMessage": "`pip_download_wheels` had stderr output:\nCommand \"python setup.py egg_info\" failed with error code 1 in /tmp/pip-wheel-97dghcl9/logging/\n\nerror: `pip_download_wheels` returned code: 1", "errorType": "InternalError", "errorId": "67DBDBF3"}}

有没有人有使用云功能在 zerodah 下交易订单的经验？

以下是我尝试过的功能：

import logging
from kiteconnect import KiteConnect

logging.basicConfig(level=logging.DEBUG)

kite = KiteConnect(api_key="xxxxxxxxxxxxxxxxxxxxxxxx")

# Redirect the user to the login url obtained
# from kite.login_url(), and receive the request_token
# from the registered redirect url after the login flow.
# Once you have the request_token, obtain the access_token
# as follows.

data = kite.generate_session("xxxxxxxxxxxxxxxxxxxxxxxxx", secret="xxxxxxxxxxxxxxxxxxxxxxxxxx")
kite.set_access_token(data["xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"])

# Place an order
def orderPlace():
    order_id = kite.place_order(
        variety=kite.VARIETY_REGULAR,
        exchange=kite.EXCHANGE_NSE,
        tradingsymbol="INFY",
        transaction_type=kite.TRANSACTION_TYPE_BUY,
        quantity=1,
        product=kite.PRODUCT_CNC,
        order_type=kite.ORDER_TYPE_MARKET
    )

    logging.info("Order placed. ID is: {}".format(order_id))
except Exception as e:
    logging.info("Order placement failed: {}".format(e.message))

requirements.txt 文件内容：

# Function dependencies, for example:
# package>=version
kiteconnect

Answer 1

错误表明您的依赖项之一是可卸载的。

看起来kiteconnect 依赖项目前与 Python 3.7 不兼容，这是 Cloud Functions 在其运行时使用的 Python 版本：https://github.com/zerodhatech/pykiteconnect/issues/55

您需要等到维护人员发布与 Python 3.7 兼容的新版本。
