How To Use VS Code Terminal: Pip Install Requests
Table of Contents :
Visual Studio Code (VS Code) is a popular code editor that has gained immense popularity among developers due to its robust features, ease of use, and extensive customization options. One of the features that make VS Code stand out is its integrated terminal, which allows developers to run shell commands directly within the editor. In this guide, we will explore how to use the VS Code terminal to install the requests library using pip. The requests library is a powerful tool in Python for making HTTP requests and is widely used for web scraping, API interaction, and more. Let’s dive in!
Getting Started with VS Code Terminal
Before we can install requests, we need to make sure we have everything set up correctly. Here’s a step-by-step guide to accessing and using the terminal in VS Code:
1. Open VS Code
Launch Visual Studio Code on your computer. If you don't have it installed, download it from the official website and install it following the instructions.
2. Open the Integrated Terminal
To open the integrated terminal in VS Code, you can use the keyboard shortcut:
- Windows/Linux: `Ctrl + `` (the backtick key, usually located above the Tab key)
- Mac: `Cmd + ``
Alternatively, you can open it via the menu by navigating to View > Terminal.
3. Check Your Python Installation
Before installing the requests library, ensure that you have Python installed on your system. You can check if Python is installed and verify its version by typing the following command in the terminal:
python --version
If you see a version number, such as Python 3.8.5, you have Python installed. If not, you will need to install Python first.
4. Ensure Pip is Installed
Pip is the package installer for Python and is included by default starting from Python 3.4. To check if pip is installed, run the following command:
pip --version
If you see a version number like pip 20.2.3, you are ready to go! If you don’t have pip installed, you’ll need to install it before proceeding.
Installing the Requests Library
Now that we have ensured Python and pip are properly installed, we can proceed to install the requests library. Follow these steps:
1. Use the Pip Command
In the VS Code terminal, type the following command:
pip install requests
This command tells pip to download and install the requests library from the Python Package Index (PyPI).
2. Wait for the Installation to Complete
Once you run the command, you will see output similar to the following:
Collecting requests
Downloading requests-2.25.1-py2.py3-none-any.whl (61 kB)
|████████████████████████████████| 61 kB 2.3 MB/s
Collecting urllib3<1.27,>=1.21.1
Downloading urllib3-1.26.5-py2.py3-none-any.whl (138 kB)
|████████████████████████████████| 138 kB 2.3 MB/s
...
Successfully installed requests-2.25.1 urllib3-1.26.5
This indicates that the requests library and its dependencies are successfully installed. 🎉
3. Verify the Installation
To verify that the requests library has been installed correctly, you can run the following command in your VS Code terminal:
pip show requests
This command will display information about the installed requests package, including its version and installation location. You should see output like this:
Name: requests
Version: 2.25.1
Summary: Python HTTP for Humans.

Important Note
Ensure your virtual environment (if using one) is activated before installing any packages. This helps to maintain project dependencies separately.
Creating a Python Script to Use Requests
Now that we have installed the requests library, we can create a simple Python script to demonstrate how to use it. Here’s how:
1. Create a New Python File
In your project directory, create a new file called app.py (or any name you prefer) using the VS Code file explorer.
2. Write Sample Code
Open app.py and enter the following code to make a simple GET request:
import requests
response = requests.get('https://api.github.com')
print(response.status_code)
print(response.json())
This code sends a GET request to the GitHub API and prints the status code and JSON response.
3. Run Your Python Script
To run your script, return to the terminal and make sure you are in the directory where your app.py file is located. Use the following command:
python app.py
You should see output similar to this:
200
{
"current_user_url": "https://api.github.com/user",
...
}
This indicates that your request was successful, and you are able to interact with the web API using the requests library.
Common Issues and Troubleshooting
When working with the VS Code terminal and installing packages, you might encounter some common issues. Here are some tips to troubleshoot:
1. Command Not Found
If you receive an error message like command not found, ensure that Python and pip are correctly added to your system's PATH.
2. Permission Errors
If you encounter permission errors when trying to install packages, try using pip with sudo on Linux or macOS:
sudo pip install requests
3. Virtual Environments
If you are working on multiple projects, consider using virtual environments. This way, you can manage dependencies without conflicts. You can create a virtual environment using:
python -m venv myenv
Activate it by running:
- Windows:
myenv\Scripts\activate - Linux/Mac:
source myenv/bin/activate
After activation, you can install packages within this environment.
Conclusion
Using the VS Code terminal to install the requests library with pip is a straightforward process that significantly enhances your ability to work with web applications and APIs in Python. With the integrated terminal, you can manage your Python projects efficiently without leaving the code editor. Always remember to verify your installations and handle any potential issues along the way. Happy coding! 🚀
