问题描述
在上一篇文章中(输入链接)下面的代码(由DebanjanB编写)
In a previous post (enter link description here) the following code (by DebanjanB)
# install firefox, geckodriver, and selenium
!apt-get update
!pip install selenium
!apt install firefox-geckodriver
!cp /usr/lib/geckodriver /usr/bin
!cp /usr/lib/firefox /usr/bin
from selenium import webdriver
binary = '/usr/bin/firefox'
options = webdriver.FirefoxOptions()
options.binary = binary
options.add_argument('start-maximized')
options.add_argument('--headless')
browser = webdriver.Firefox(firefox_options=options, executable_path='/usr/bin/geckodriver')
browser.get('http://google.com/')
这是正确的，导致版本问题.我不是 Ubuntu 的专家.
which is correct, caused a version problem. I'm not an expert in Ubuntu.
我使用Google Colaboratory，Python3.6，Selenium3.14.

I searched the internet and only found that this is a version conflict between Firefox and Geckodriver. But nobody gives the solution how to choose the compatible versions. This is my problem. Any help is appreciated.
推荐答案
在注释中进行所有讨论之后，您似乎似乎错了下载 GeckoDriver 的命令，并且可能下载和/或安装时遇到了一些问题 Firefox .
After all the discussion within the comments it seems you erred the command to download GeckoDriver and possibly some issues with downloading and/or installing Firefox.
在内安装 geckodriver 的命令href ="/questions/tagged/ubuntu" class ="post-tag" title =显示标记了'ubuntu'"的问题rel ="tag"> ubuntu 容易出错:
The command to install geckodriver within ubuntu was error prone:
!apt install firefox-geckodriver
以下是详细步骤:
-
浏览到 geckodriver版本页面.检查适用于您平台的 GeckoDriver 的兼容版本，并按以下方式下载:
Browse to the geckodriver releases page. Checkout the compatible version of GeckoDriver for your platform and download it as follows:
wget https://github.com/mozilla/geckodriver/releases/download/v0.24.0/geckodriver-v0.24.0-linux64.tar.gz
使用以下方法提取文件:
Extract the file with:
tar -xvzf geckodriver*
使其可执行:
Make it executable:
chmod +x geckodriver
将驱动程序添加到您的PATH中，以便其他工具可以找到它:
Add the driver to your PATH so other tools can find it:
export PATH=$PATH:/path-to-extracted-file/.
Firefox
Firefox的所有受支持版本中始终提供最新版本的Firefox作为安全更新，并且将安装常规更新.您需要启用安全性或更新存储库(例如Software & Updates-> Updates).您需要默认启用Security，但最好检查软件包管理器是否默认不更新Firefox.
Firefox
The latest version of Firefox is always available as a security updates in all supported releases of Ubuntu and a normal update will install it. You need to enable the security or you need to update the repositories (e. g. Software & Updates -> Updates). You need to enable the Security by default but better to check if the package manager doesn't updates Firefox by default.

更新
Selenium Client Driver 页面提到:
Update
Selenium Client Driver page mentions:
-
支持的Python版本:
Supported Python Versions:
Python 2.7, 3.4+
但是硒3.141.0 页面上的列表仅包括:
But the list on selenium 3.141.0 page includes only:
- Python :: 2.7
- Python :: 3.4
- Python :: 3.5
- Python :: 3.6
因此可能仍不支持 Python 3.7 ，您可能必须降级到相关版本.
So possibly Python 3.7 is still not supported and you may have to downgrade to a relevant version.
