我一直有 Traceback（最近一次調用最后一次）：每次運行下面的 selenium 文件時出錯。 我怎樣才能解決這個問題？

Question

我在 python 中運行帶有以下代碼的 selenium 文件，並且我一直遇到回溯調用錯誤。 我說不出問題是什么。 以下是我一直遇到的錯誤：

[Traceback (most recent call last): File "C:\Users\Whizzy.Ellah\PycharmProjects\virtual_assistant_final_year_project\selenium_web.py", line 2, in from selenium import webdriver File "C:\anacondaF\envs\finalYrProject\lib\site-packages\selenium\webdriver_init_.py", line 18, in from .firefox.webdriver import WebDriver as Firefox # noqa File "C:\anacondaF\envs\finalYrProject\lib\site-][1]Traceback (most recent call last):

    import urllib3
ModuleNotFoundError: No module named 'urllib3'

Process finished with exit code 1

我的代碼：

import time
from selenium import webdriver
from selenium.webdriver import chrome

class web_driver_info():
    def __int__(self):
        self.driver = webdriver.Chrome(executable_path=r'C:\\Users\\Whizzy.Ellah\\PycharmProjects\\virtual_assistant_final_year_project\\chromedriver.exe')       

    def get_info(self, query):                 
        self.query = query                     
        self.driver.get(url='https://www.wikipedia.org')          


class_instance = web_driver_info()
class_instance.get_info("Hello")

Answer 1

urllib3 未導入或未安裝。

要導入，請使用

import urllib3

在文件的頂部。 要安裝寫入：

pip install urllib3

進入終端。

Answer 2

除了@Ankit_Gunner在他們的回答中提到的兩個原因之外：

urllib3 未導入或未安裝。

可能還有另一種可能性，如下所示：

• urllib3或requests模塊已過時，需要更新。

在這種情況下，您需要將urllib3 / requests模塊升級為：

• 使用pip ：

   pip install --upgrade requests

• 使用pip3 ：

   pip3 install --upgrade requests

Answer 3

這最終對我有用

I tried changing the virtual environment from anaconda to python virtual environment by deactivating the anaconda virtual env that is being used by typing conda deactivate finalYrProject (finalYrProject is the name of my virtual environment) through the anaconda command prompt.

Also, I had to change the base interpreter - ie Python interpreter by clicking on the file tab in Pycharm > settings > Python interpreter > settings' icon near the already used python interpreter selected > Show All and selected from the list of Python interpreters I had . 再次運行代碼后一切正常。
