Installing Google Chrome
1. Visit the official download page:
Navigate to Google Chrome’s official website and download the appropriate version for your operating system.
2. Install the package:
- For Windows: Run the installer and follow the on-screen instructions.
- For Mac: Open the downloaded `.dmg` file and drag the Chrome application to the Applications folder.
- For Linux: Depending on your distribution, use `dpkg` (for Debian/Ubuntu) or `rpm` (for Fedora/Red Hat):
sudo dpkg -i google-chrome-stable_current_amd64.deb # For Debian/Ubuntu
sudo rpm -i google-chrome-stable_current_x86_64.rpm # For Fedora/Red Hat sudo yum install ./google-chrome-stable_current_x86_64.rpm # Alternative
Installing ChromeDriver
1. Determine your Chrome version:
Open Google Chrome, click on the three vertical dots on the top right -> Help -> About Google Chrome. Note down the version number.
2. Download the appropriate ChromeDriver:
Visit the ChromeDriver download page and download the version that matches your Chrome version.
3. Extract and move ChromeDriver:
- For Windows: Extract the downloaded ZIP file and move `chromedriver.exe` to a location in your system’s PATH or any directory.
- For Mac/Linux: Extract the downloaded ZIP/tar file:
unzip chromedriver_win32.zip # For Windows
tar -xvf chromedriver_mac64.zip # For Mac
tar -xvf chromedriver_linux64.tar.gz # For Linux
Move the `chromedriver` to `/usr/bin/` or any location in your system’s PATH:
sudo mv chromedriver /usr/bin/
Setting Up a Python Virtual Environment
1. Check your Python version:
Determine your Python version with:
python --version
If you have both Python 2 and Python 3 installed, it might be:
python3 --version
2. Create a new virtual environment:
Use one of the following, based on your Python version:
python -m venv venv
OR
python3 -m venv venv
3. Activate the virtual environment:
- For Windows:
.\venv\Scripts\activate
- For Mac/Linux:
source venv/bin/activate
Your terminal or command prompt should now display `(venv)` at the start, indicating that the virtual environment is active.
Installing Selenium
With the virtual environment active, install Selenium:
pip install selenium
Verifying Installation
1. Verify Google Chrome:
Run `google-chrome` from the terminal (or cmd on Windows) or find Google Chrome in your applications and launch it.
2. Verify ChromeDriver:
Execute:
chromedriver --version
This should match the Google Chrome version you noted earlier.
3. Verify Selenium:
Run:
pip show selenium
This will display Selenium package details, confirming its installation in your virtual environment.
Troubleshooting
- Ensure Google Chrome and ChromeDriver versions match.
- If you encounter PATH issues, verify `chromedriver` is in a directory within your system’s PATH.
- On Linux, if `chromedriver` has permission issues, grant it executable permissions: `chmod +x chromedriver`.
