Using Python 3 in virtualenv

🐍 Using Python 3 in virtualenv

So you're running your projects using virtualenv, but you need to use Python 3.4 for a specific project. No worries! I've got you covered. In this guide, I'll walk you through the steps to create a virtualenv that uses Python 3.4. Let's get started! 👩‍💻

Step 1: Install Python 3.4 📥

First, you need to install Python 3.4 on your Mac. You can do this by running the following command in your terminal:

brew install python3

This command will install Python 3.4 on your system. Great! 🎉

Step 2: Create a virtualenv 🗃️

Now that you have Python 3.4 installed, let's create a virtualenv that uses this version. In your terminal, navigate to the desired directory and run the following command:

virtualenv -p python3.4 envPython3

This command creates a new virtual environment named envPython3 that uses Python 3.4. Easy, right? 😉

Step 3: Activate the virtualenv 💻

To start using your newly created virtualenv, you need to activate it. Run the following command:

source envPython3/bin/activate

After running this command, you'll see that your terminal prompt has changed, indicating that you're now working within the virtualenv. Cool! 😎

Step 4: Verify Python version ✅

Finally, let's verify that you're indeed using Python 3.4 within your virtualenv. Run the following command:

python --version

You should see the output Python 3.4.x, where x represents the patch version of Python 3.4. If you see this output, congratulations! You're all set to start working with Python 3.4 in your virtualenv. 🚀

Common Issues and Troubleshooting ❌🔍

In case you encounter any issues during the process, here are some common problems and their solutions:

1. ImportError: No module named '_collections_abc':

   • Solution: Try reinstalling virtualenv by running pip install --upgrade virtualenv.

2. ERROR: virtualenv is not compatible with this system or executable:

   • Solution: Make sure you have the latest version of virtualenv installed by running pip install --upgrade virtualenv.

Remember to consult the virtualenv and Python documentation for more detailed information on troubleshooting. 🔎
