我一直有 Traceback（最近一次调用最后一次）：每次运行下面的 selenium 文件时出错。 我怎样才能解决这个问题？

Question

I'm running a selenium file with the following code in python and I keep having a traceback call error. I can't tell what the problem is. Below is the error I keep having:

[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

My code:

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

Either urllib3 is not imported or not installed.

To import, use

import urllib3

at the top of the file. To install write:

pip install urllib3

into terminal.

Answer 2

Apart from the two reasons mentioned by @Ankit_Gunner in their answer that:

Either urllib3 is not imported or not installed.

There can be another possibility as follows:

• urllib3 or requests module is backdated and needs a update.

In that case you need to upgrade urllib3 / requests module as:

• Using pip :

   pip install --upgrade requests

• Using pip3 :

   pip3 install --upgrade requests

Answer 3

This is what finally worked for me

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. And after running the code again everything works fine.
