ImportError in the console, but import is working in PyCharm

ghz 昨天 ⋅ 0 views

I have a programm which imports the request module like this:

import urllib
from urllib import request
...

The programm is running fine in the PyCharm-IDE. But when I run the same code in the console in Linux Ubuntu I get the error:

ImportError: cannot import name request

Is there a problem with my path? Should I provide more information to solve this problem?

But when I add this working directory to my script like:

import sys
sys.path.append('/home/kame/Dropbox/myCode/python/scripts/')

I still get the same error.

Answer

The issue you're encountering could be related to how Python's import system is resolving the urllib module in different environments.

Here are a few things to check and try:

1. Check for Conflicting Files:

One common issue when encountering this error is that there might be a file named urllib.py or request.py in your working directory or in the same path where your script is located. Python might be trying to import that file instead of the standard library module.

Run this in both PyCharm and the terminal to check what urllib and request are pointing to:

import urllib
print(urllib.__file__)

from urllib import request
print(request.__file__)

This will show you the file paths of the modules Python is loading. If the paths don't point to the standard Python library, you might have a conflicting file.

2. Check Python Versions:

Another possible cause of the issue is that the Python environment in the terminal could be different from the one in PyCharm. PyCharm might be using a virtual environment or a different version of Python. Run the following command to check which Python version you're using in the terminal:

python --version

Compare it to the Python version configured in PyCharm to ensure you're using the same version.

3. Use Absolute Imports:

Try importing urllib.request directly, as it's the submodule you're working with:

import urllib.request

This way, you avoid the ambiguity that might arise from from urllib import request.

4. Virtual Environment in Console:

If you're using a virtual environment in PyCharm, make sure you're activating the same virtual environment in the terminal. You can activate it by running:

source /path/to/venv/bin/activate

After activating the virtual environment, try running your script again in the terminal.

5. Check for PYTHONPATH Issues:

If your sys.path.append() line doesn't resolve the issue, try checking the current PYTHONPATH environment variable in your terminal:

echo $PYTHONPATH

If PYTHONPATH is incorrectly set or missing, Python might not be able to find the standard library. You can reset it or set it explicitly by:

export PYTHONPATH=/usr/lib/pythonX.X

Replace X.X with your Python version.

6. Reinstall Requests Module:

If none of the above works, there might be an issue with the requests module (even though it's not directly related to your import). You can try reinstalling it:

pip install --upgrade --force-reinstall requests

After checking these, let me know if the problem persists or if any of these steps help resolve it!
