bs4 python module issue

Question

When I run the command:

python checker.py capture.xml indication NULL

I get the error:

Traceback (most recent call last): File "checker.py", line 1, in ModuleNotFoundError: No module named 'bs4'

so I decided install bs4 in Python 24 but when I do:

pip install bs4

I get this message:

Requirement already satisfied: bs4 in c:\program files\python36\lib\site-packages Requirement already satisfied: beautifulsoup4 in c:\program files\python36\lib\site-packages (from bs4) You are using pip version 9.0.1, however version 18.1 is available. You should consider upgrading via the 'python -m pip install --upgrade pip' command.

so indeed, the module is in that folder so I added c:\program files\python36\lib\ to the path environment variable just in case, but I'm getting the same thing.

Any idea on how to solve this, please?

Answer 1

It seems likely that your python command is referencing Python 2.4 (or some other installation of Python), while pip is referencing the version of pip installed with Python 3.6 in e.g. C:\Program Files\Python36. You can double-check the location of the python.exe called from the command line with where python.

Assuming the location returned by where python isn't e.g. C:\Program Files\Python36\python.exe, I would suggest checking both your User PATH and System Path environment variables. Make sure that e.g. C:\Program Files\Python36 is present and remove any similar references to alternate Python installations.

The other (non-destructive) option is to simply specify the full path to the python.exe you wish to use e.g.:

"C:\Program Files\Python36\python.exe" checker.py capture.xml indication NULL

Notes

• Since you have Python 3.6 installed, you may have the Python Launcher for Windows installed as well. If this is the case, you can try replacing python with e.g. py -3.6 like so:

  py -3.6 checker.py capture.xml indication NULL
  

• I have made some assumptions about capitalization in the paths above. Obviously, you should use whatever capitalization suits your installation.

• While I don't believe this is relevant to answering your particular question, as a tip I would suggest installing Python into a directory without spaces (i.e. not C:\Program Files). This can help eliminate potential problems with file or folder paths in the future.
