How to Start a Simple Web Server in Python 3 on Mac

If you’re a Python user on a Mac, you might already know that you can create a simple web server using a script. However, if you’ve recently upgraded to Python 3, the traditional script won’t work. But don’t worry, you can still start a web server using Python 3 on your Mac with a slightly different command. In this guide, we’ll show you how to start a simple web server in Python 3 on Mac.

Starting a Web Server in Python 3.0+

If you already have Python 3.0+ installed or upgraded on your Mac, you can start a web server using the following command:

python -m http.server

or

python3 -m http.server

Simply enter the command in the terminal and hit enter. The web server will start immediately, serving files from the directory where the command was executed. You can access the server by opening the URL http://0.0.0.0:8000 in any browser on your computer.

Python3 Equivalent of python -m for CGIHTTPServer

If you need to run a Python Common Gateway Interface (CGI) server for CGI scripts in Python or Perl, you can use the following command:

python3 -m http.server --cgi

or

python -m http.server --cgi

Make sure to include the –cgi flag to start the CGI HTTP server in Python 3.

Error: “/usr/bin/python: No module named http”

If you encounter this error when running the python -m http.server script, it means you’re either not using Python 3 or using the wrong command for python3. Make sure you’re using the correct version and command, depending on how it was installed or upgraded on your Mac. If you’re using an older version of Python, you can try using the command python -m SimpleHTTPServer for Python 2 and earlier.

While Python simple web servers are great for testing and development purposes, they are not intended for production environments. For a more stable and secure web server, consider using Apache or Nginx. Alternatively, you can use MAMP to easily set up a complete Apache, MySQL, and PHP environment on your Mac.
