Unable to set default python version to python3 in ubuntu
📝🐍💻 Introducing the Ultimate Guide to Setting Default Python Version to Python 3 in Ubuntu! 🚀🔥
Are you an Ubuntu user struggling to set the default Python version to Python 3? 😓 Don't worry, you're not alone! Many developers face this common issue, and we're here to help you conquer it with ease! 💪👊
In Ubuntu 16.04, the default Python version is Python 2.7, but if you prefer to use Python 3 as your default version, follow these simple steps. Let's dive in! 🏊♂️💻
Open your terminal and enter the following command:
update-alternatives --remove python /usr/bin/python2
This command removes the link to the Python 2 executable, allowing us to set Python 3 as the default version. However, the real magic happens in the next step! ✨
Now, execute the following command:
update-alternatives --install /usr/bin/python python /usr/bin/python3 1
🔍 Ah, but hold on! If you receive the following error message:
update-alternatives: --install needs <link> <name> <path> <priority>
Use 'update-alternatives --help' for program usage information.Do not fret! It means you forgot to include the priority level (in this case, we set it as 1). 🙃
To fix this, simply modify the command and include the priority level like this:
update-alternatives --install /usr/bin/python python /usr/bin/python3 <priority>Replace <priority> with a number higher than the priority level of any other alternative Python version listed in the output of the next command we're going to run. 😉
Lastly, execute this command to configure Python 3 as your default Python version:
sudo update-alternatives --config python
This command allows you to choose the default Python version interactively. You'll be presented with a list of available Python versions, including the one we just installed. Simply type the corresponding number and hit Enter! 🎉
Boom! You did it! 🎆✨ Now, your default Python version will be set to Python 3, and you'll be able to enjoy all the amazing features and enhancements it offers. 🐍💕
Remember, setting the default Python version to Python 3 is crucial for compatibility and taking advantage of the latest packages and improvements. So why wait? Jump right in and make the switch today! ⚡🔛
