A, Python installation

Under Window System, python installation is very simple. Access python.org/download, download the latest version, the installation process is similar to other windows software. Remember to set the path environment variable After downloading, then the Windows command line you can call:

Two, the Selenium installed (installation methods, the first through PIP)

Python3.x will have after installation default pip (Pip.exe Scripts default path in the python), using pip installation selenium:

pip install selenium

It can be followed by an equal sign specified selenium version: such as:pip install selenium==2.53.0

 

I have installed because of selenium, can not repeat the installation.

Use the following command to see if the installation was successful:

pip show selenium

The second: by downloading selenium-python source code package

After downloading the source packageThe source package extract to any path

Cmd command line by entering the directory, enter python setup.py install, no error message the installation is successful

Can be successfully installed by entering pip list verification

Three, Firefox installation

Due to install the latest Firefox compatible with selenium as a problem, install the Legacy firefox47, remember to install the plug-and firepath firebug in firefox.(In addition, remember to turn off the automatic installation firefox)

Older Firefox Download: http: //ftp.mozilla.org/pub/firefox/releases/

Note: Because of compatibility issues Selenium browser, the browser can not be used to date. The use of Firefox is version 39

2) After installation off automatic update feature, to prevent the upgrade is not available

a. Open Firefox, select "Tools" column --- "Options"

b. In the pop-up "Options" box, we select the "Advanced" --- "Update", check the following "do not check for updates" and then OK to exit.

c. Locate Firefox profile folder, find the file prefs.js in the configuration directory

General Configuration folder path is: C: \ Users \ user \ AppData \ Roaming \ Mozilla \ Firefox \ Profiles

7 prefs.js file with the end line, as follows:

user_pref("app.update.migrated.updateDir",false);

user_pref("app.update.lastUpdateTime.browser-cleanup-thumbnails",0);

user_pref("app.update.lastUpdateTime.datareporting-healthreport-lastDailyCollection",0);

user_pref("app.update.disable_button.showUpdateHistory",false);

user_pref("app.update.service.enabled",false);

user_pref("browser.search.update",false);

user_pref("extensions.update.enabled",false);

Then save prefs.js, close to exit. This will completely ban the upgrade of the Firefox browser

Fourth, the installation driver ()

Selenium 3 Previously, firefox browser, no additional driver. But Selenium 3.X for firefox browser also need to install the driver:

Firefox browser to be installed geckdriver, download address: https: //github.com/mozilla/geckodriver/releases;

Appropriate, Chrome browser to install chromedriver, IE browser to install IEdriver.

driver's path can be placed directly under python path, I have here the driver placed under Scripts python path, while adding the script path environment variable.

Fifth, run a simple example

Use python IDLE comes tool, enter the following script:

from selenium import webdriver # Import package webdriver

import time

driver = webdriver.Firefox () # initialize a Firefox instance: driver

 

driver.maximize_window () # maximize browser

time.sleep (5) # pause for five seconds

 

driver.get ( "https://www.baidu.com") # by get () method to open a url site

Running the above script, the final open Baidu website, run prove successful.

PS, my operating environment:

Firefox browser version: Firefox 47.0

Python：python v3.6.2

Selenium：3.7.0

Geckdriver：v0.15.0
