Question

当我输入以下内容时，它表明我已经安装了请求模块：pip3 install requests

响应：

Requirement already satisfied: requests in /usr/local/lib/python3.7/site-packages (2.24.0)
Requirement already satisfied: idna<3,>=2.5 in /usr/local/lib/python3.7/site-packages (from requests) (2.9)
Requirement already satisfied: urllib3!=1.25.0,!=1.25.1,<1.26,>=1.21.1 in /usr/local/lib/python3.7/site-packages (from requests) (1.25.8)
Requirement already satisfied: certifi>=2017.4.17 in /usr/local/lib/python3.7/site-packages (from requests) (2019.11.28)
Requirement already satisfied: chardet<4,>=3.0.2 in /usr/local/lib/python3.7/site-packages (from requests) (3.0.4)

因此，当我使用代码创建名为http.py的文件时

import requests

url = "https://google.com"
response = requests.get(url)
print(f"your request to {url} came back w/ status code {response.status_code}")

我收到一条错误消息：

Traceback (most recent call last):

    response = requests.get(url)
AttributeError: module 'requests' has no attribute 'get'

但是当我使用python2运行此代码时：

import requests

url = "https://google.com"
response = requests.get(url)
print(response.status_code)

我没有任何错误并打印出：200

我尝试使用pip3卸载并重新安装请求，但这不能解决问题。奇怪的是，当我在终端中使用相同的代码运行python3时，它可以工作：

Python 3.7.3 (default, Jun 19 2019, 07:38:49)
[Clang 10.0.1 (clang-1001.0.46.4)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
>>> url = "https://google.com"
>>> response = requests.get(url)
>>>
>>> print(f"your request to {url} came back w/ status code {response}")
your request to https://google.com came back w/ status code <Response [200]>
>>>

Answer 1

问题是您的http.py文件，只需将其重命名为其他文件即可。有一个http package，基础库（urllib3）正在从中导入一些模块。

Answer 2

您的cwd中是否有一个名为requests.py的文件？如果存在，则应重命名它，并确保它与python的任何其他模块都不匹配，否则会出现错误。

请求模块不适用于Python3，但适用于python
