請求模塊不適用於 Python3，但適用於 Python

Question

當我輸入時，它顯示我已經安裝了請求模塊： pip3 install requests

回復：

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)

所以當我用代碼創建一個名為 http.py 的文件時：

import requests

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

我收到一條錯誤消息：

Traceback (most recent call last):

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

但是當我用 python2 運行這段代碼時：

import requests

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

我沒有錯誤並打印出來： 200

我曾嘗試使用 pip3 卸載和重新安裝請求，但這並不能解決問題。 奇怪的是，當我使用相同的代碼在終端中運行 python3 時，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

問題在於您的http.py文件，只需將其重命名為其他名稱即可。 有一個http 包，底層庫 ( urllib3 ) 正在urllib3導入一些模塊。

Answer 2

你的 cwd 中有一個名為 requests.py 的文件嗎？ 如果它在那里，那么你應該重命名它並確保它與 python 的任何其他模塊不匹配，否則你會得到一個錯誤。
