Question

我需要在我的应用中使用请求。我按照here所描述的发出HTTP（S）请求的说明进行了操作。

我在代码中调用request_toolbels就像这样

from flask import Flask
from routes import configure_blueprints
from modules.filters import init_babel
import requests
import requests_toolbelt.adapters.appengine


def create_app():
    """Create the Flask App"""
    v = requests.__version__

    requests_toolbelt.adapters.appengine.monkeypatch()
    app = Flask(__name__)
    configure_blueprints(app)
    init_babel(app)
    return app

当我调试v的值是2.6.0时。但我确定我已经安装了请求2.11.1

运行单元测试时出现以下错误。

requests_toolbelt.exceptions.VersionMismatchError: The toolbelt requires at least Requests 2.10.0 to be installed. Version 2.6.0 was found instead.

Answer 1

这是因为appengine sdk有自己的请求版本。你需要安装sdk 1.9.49来获取请求2.10 旧版本的appengine sdk登陆请求2.6.0

您在lib目录中安装的请求版本无关紧要。 Appengine始终默认为其自己的请求版本。

Answer 2

pip install requests==2.10.0将解决此问题

requests_toolbelt.exceptions.VersionMismatchError：工具带至少需要安装Requests 2.10.0。发现版本2.6.0
