Tag Archives: Chromedriver

Mac environment and python + selenium environment are built to solve the error reporting problem of chromedriver

####

Create a new Python virtual environment and install selenium

Create a new Python project,

####

from selenium import webdriver

driver = webdriver.Chrome()

driver.get("https://www.baidu.com")

###

report errors:

‘chromedriver’ executable needs to be in PAT

###

What should I do?

Download chromedriver

Step 1: check your browser version and enter the URL: chrome://version/

Step 2: download the corresponding version of chromedrive at: http://chromedriver.storage.googleapis.com/index.html

Step 3: put the package under the project directory,

Step 4: modify the code and add the file path of drive,

Here is the code:

###

from selenium import webdriver

driver = webdriver.Chrome(executable_path="./chromedriver")

driver.get("https://www.baidu.com")

###

Then you can play happily. As long as you master the positioning and various operation APIs, you can basically get started and do your own projects,

Solution: modify the files in the appium installation directory, for example:

D:\Program Files\Appium\node_modules\appium\lib\devices\android\android-hybrid.js

Find the androidhybrid.startchromedriverproxy function and comment out the relevant contents

 

 

Cause of problem:

When appium switches to the HTML page for the first time, a new chrome driver will be generated; When switching to HTML for the second time, the existing chrome driver will be used. But in fact, every time we open an activity in our application, we usually re create a webchromeclient, so here we change it to generate a new chromedriver anyway
