ModuleNotFoundError: No module named 'pysnmp'

[atech1973]

Hello I am new to this library and not that much familiar with Python.

I have installed python 3.9.4 in Win10x64 platform and pip 23.0.1 and installed pysnmp successfully using pip install pysnmp command. However, when I run an example code to "fetch snmp variable" from this library "Quick Start" page, (https://pysnmp.readthedocs.io/en/latest/quick-start.html). I get this error.

######################################################### SyntaxError: multiple statements found while compiling a single statement

To add more insight to this issue, I have discovered another similar thread to mine which alerted me to check the python pip list. Similar other thread link: https://github.com/etingof/pysnmp/issues/420

####################################### When I ran pip list I can see pysnmp was installed Package Version

---

pip 23.0.1 ply 3.11 pyasn1 0.4.8 pycryptodomex 3.17 pysmi 0.3.4 pysnmp 4.4.12

And py -m pip list command did not list pysnmp in the list but it gave me warning that I had an older pip installed.

Package Version

I ran this command and old pip was updated.

After this if run command py -m pip list > I still don't see pysnmp in the list but pip list shows me pysnmp in its list Package Version

pip 23.0.1 ply 3.11 pyasn1 0.4.8 pycryptodomex 3.17 pysmi 0.3.4 pysnmp 4.4.12

I anyone has had this experience then please if you can help me out?

Further to this problem resolution I have added my pip path to my environment path as well but still running the py -m pip list does not print the pysnmp being in the list.

If I type pip without anything else, the path is shorter then if I run pip -V command. see below. C:\Users\atech1973\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\python.exe -m pip [options]

As mentioned above, if I run pip -V command, I have pip Ver. 23.0.1 running but just noticed it's working directory is in a weird location and I am not sure if this is its working director that I should add to window path or the one above.

C:\Users\atech1973\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.9_qbz5n2kfra8p0\LocalCache\local-packages\Python39\site-packages\pip (python 3.9)

If I brows to the second long path location, I can see pysnmp diectory is in here.

Lastly I have added the following path to my Windows path Env. and still I get the same error when I run the program that tries to import pysnmp.

1. You are reading one of the worst sources of PySNMP documentation. Please read #429 for more details. That web page was set up by someone who has no relationship to the original author and has no intention to keep the information up-to-date or even technically correct. Unfortunately Google puts it at top of search results which shows how poor that search engine is.
2. You will have to be a good enough Python user/developer in order to make good use of this library.

It will be rather lengthy to teach you enough Python, unless you buy great books/tutorials or just hire a consultant. So, the only tip I want to say is to learn the actual path of python.exe on your machine, and then perform all other operations with that executable. For example, use python.exe -m pip list and python.exe -m pip install to verify/install packages, then use python.exe yourscript.py to execute your test script.

A tool like VS Code + Microsoft Python extension can easily guide you on which python.exe to use, so I never use IDLE Shell or the editor you used.
