Python:没有名为 selenium 的模块 [英] Python : no module named selenium

问题描述

在网上搜索了几个小时后，我还没有找到问题的答案.我正在使用 Python 3.6，但无法导入 selenium.我总是收到消息没有名为‘硒’的模块"我尝试了一切，我首先从这个网站下载了 selenium https://pypi.python.org/pypi/selenium/3.6.0 .

After searching the web for hours i didnt yet find an answer to my problem. I am using Python 3.6 and i cant import selenium. I always get the message "No module named 'selenium'' I tried everything, i first downloaded selenium from this website https://pypi.python.org/pypi/selenium/3.6.0 .

然后我尝试了 python -m pip install -U selenium 也没有工作.我尝试了人们所说的其他一些东西，但它们也不起作用.我使用的是 Windows 10.有什么帮助吗?

Then I tried python -m pip install -U selenium and didnt work either. I tried some other things that people said but they didnt work either. Im using windows 10. Any help?

通过 pip 安装最新的 selenium :

C:Usersusername>pip install -U selenium
Collecting selenium
  Downloading selenium-3.8.1-py2.py3-none-any.whl (931kB)
    100% |¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦| 942kB 322kB/s
Installing collected packages: selenium
Successfully installed selenium-3.8.1

确认Selenium 已安装:

C:Usersusername>pip freeze
selenium==3.8.1 

打开一个IDE(例如Eclipse、PyCharm)并编写一个简单的程序如下:

Open an IDE (e.g Eclipse, PyCharm) and write a simple program as follows :

from selenium import webdriver

driver = webdriver.Firefox(executable_path="C:\path\to\geckodriver.exe")
driver.get('https://stackoverflow.com')

执行启动 Firefox Quantum 浏览器的程序和 url https://stackoverflow.com 将被访问.

Execute the program on which Firefox Quantum Browser will be initiated and the url https://stackoverflow.com will be accessed.
