How to Fix "python: can‘t open file ‘manage.py‘: [Errno 2] No such file or directory" - A Comprehensive Guide

As a fellow tech geek and Python developer, I totally get how frustrating that "can‘t open file ‘manage.py‘" error can be. You‘re just trying to run your Django server or make some migrations, and boom—Python throws this cryptic error saying your manage.py file doesn‘t exist. Not cool, Python. Not cool.

But don‘t worries my friends, this is a super common issue that every Pythonista runs into at some point. The good news is, it‘s usually a quick fix! In this comprehensive guide, I‘ll walk you through all the possible causes of the "can‘t open manage.py" error and show you how to troubleshoot step-by-step.

Stick with me, and we‘ll have you up and running again in no time. Let‘s do this!

Overview: Why Am I Seeing This Error?

When you create a new Django project, Django automatically generates a manage.py file for you. This file contains helper scripts that let you run various management commands for your project—things like running the dev server, creating migrations, running tests, etc.

Python expects to find this manage.py file in the top-level directory of your project. So if you try running a command like:

python manage.py runserver

…and Python can‘t find the manage.py file there, you‘ll see this error:

python: can‘t open file ‘manage.py‘: [Errno 2] No such file or directory

There are a few common reasons why Python might not be able to find or open manage.py:

You deleted manage.py – Maybe you were tidying up your project folder and accidentally deleted it?
You renamed manage.py – For example, to manage.py.txt or something else.
You moved manage.py – Like putting it in a sub-folder instead of the project root.
Typo in the file name – Like calling it mangae.py or managpy. Sneaky typos!
Permission error – The file exists, but Python doesn‘t have permission to open/read it.

The good news is, all of these issues can be fixed pretty easily. So let‘s walk through how to diagnose and troubleshoot each one!

Step 1: Check You‘re in the Right Directory

The first thing to check is that you‘re running the python manage.py command from the correct directory.

You‘ll want to be in the top-level project folder—the one that contains manage.py.

So open up your terminal, navigate to your project root, and run an ls command to list the contents. You should see manage.py in the output:

Macbook:~/projects/myproject$ ls
manage.py requirements.txt ...

If you don‘t see manage.py listed, you‘re likely in the wrong folder! Use cd to navigate to the correct project root directory and try again.

Step 2: Verify manage.py Exists

Okay, assuming you‘re in the right directory, let‘s check that the manage.py file does actually exist here.

Run an ls command and inspect the output to see if manage.py is listed.

If not, it likely means the file has been deleted or moved somewhere else accidentally. We‘ll cover how to fix that next.

Step 3: Check for Renames or Typos

If manage.py is missing, it‘s possible you (or someone else) renamed it to something else inadvertently.

Carefully inspect the files in your project root and see if any look like they could be a renamed manage.py.

For example:

manage.py.txt
mangae.py
managpy
django-manage.py

Typos are very sneaky! Double check the filename, correct any typos, and rename it back to manage.py if needed.

You can rename a file on Linux/macOS using:

mv misnamed_file.py manage.py

And on Windows:

ren misnamed_file.py manage.py

Now when you run ls again, manage.py should appear. On to the next step!

Step 4: Move manage.py Back to Project Root

Another possibility is that manage.py exists, but it‘s located in a subdirectory instead of the project root.

Maybe you accidentally moved it while organizing files, or it ended up in the wrong spot when cloning a repo.

No worries – we can easily move it back.

First, find where manage.py is located. Search your entire project directory if needed:

find . -name "manage.py"

Once you‘ve located it, move it back to the project root using mv:

mv subfolder/manage.py .

The . specifies to move it to the current directory, which should be your project root if you followed step 1.

Double check with ls that manage.py is now in the right spot, and you should be set!

Step 5: Check File Permissions

One last potential issue – a permission problem could prevent Python from being able to open manage.py, even if it‘s there.

On Linux/macOS, run:

ls -l manage.py

And make sure you have read and execute permissions on the file.

If not, update permissions:

chmod +rx manage.py

And verify again with ls -l that it worked.

With permissions set properly, the error should disappear!

Step 6: Try Running manage.py Again!

Okay, we‘ve covered a ton of potential fixes:

Navigating to the correct directory
Checking manage.py exists
Fixing typos/renames
Moving it back to project root
Setting file permissions

With any luck, those steps resolved your "can‘t open manage.py" issue!

Try running your command again:

python manage.py runserver

And it should now work perfectly! Welcome back 🙂

If not, here are a few other quick things to check:

Make sure your virtual environment is activated
Check you‘re using the right Python version
Try the full path like python /full/path/to/manage.py runserver
