Re: [Tutor] Running programs that import 3rd party packages installed using pip.
That's very helpful, thanks. After reading the Tutor information last night, I wrote a little program I named sysinfo. The code run line by line in a Spyder console yields: In [3]: sys.path Out[3]: ['', 'C:\\Users\\rba21\\Anaconda3\\python36.zip', 'C:\\Users\\rba21\\Anaconda3\\DLLs', 'C:\\Users\\rba21\\Anaconda3\\lib', 'C:\\Users\\rba21\\Anaconda3', 'C:\\Users\\rba21\\Anaconda3\\lib\\site-packages', 'C:\\Users\\rba21\\Anaconda3\\lib\\site-packages\\win32', 'C:\\Users\\rba21\\Anaconda3\\lib\\site-packages\\win32\\lib', 'C:\\Users\\rba21\\Anaconda3\\lib\\site-packages\\Pythonwin', 'C:\\Users\\rba21\\Anaconda3\\lib\\site-packages\\IPython\\extensions', 'C:\\Users\\rba21\\.ipython'] In [4]: sys.version Out[4]: '3.6.5 |Anaconda, Inc.| (default, Mar 29 2018, 13:32:41) [MSC v.1900 64 bit (AMD64)]' In [5]: sys.platform Out[5]: 'win32' I'll have to do more research to figure out which folders I need to add given that '\site-packages' is already included, but at least I won't be looking at the wrong path variable.

Re: [Tutor] Running programs that import 3rd party packages installed using pip.
Thanks! That helps. I'll have to go back to the drawing board, but you've put me on the right "path". On Thu, Oct 4, 2018 at 12:47 AM Alan Gauld via Tutor wrote: > > On 04/10/18 04:20, Roger B.

Write this simple program and run it from the "command line": import sys print(sys.path) those are the places Python will look for modules when importing. you can add to sys.path in your program, or if you define PYTHONPATH, its contents will show up in sys.path. if you now do the same thing in a program running inside Spyder, you'll probably see differences in sys.path. as Alan said, the system/user environment paths have nothing to do with Python's module importing. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor

[Tutor] Running programs that import 3rd party packages installed using pip.
System: Windows 10, Anaconda, Python 3, Spyder3 Problem: Running programs that import requests, pyperclip, bs4 and/or other modules from 3rd party packages works fine within Spyder IDE, but not from command line, or Win/R. The error message indicates no such module. Therefore, my programs crash at the import statement. In contrast, programs using built in modules work fine everywhere. Questions: Which file needs to be found? Is this a path problem? Efforts to solve problem: After making sure I had correctly typed the module names, my second guess was that it is a path problem, so I used win explorer to locate the module files. I also went to the command line and used "pip show modname". The search using win explorer revealed module files in multiple directories, so part of the problem may be that I don't know which file the import statement needs to be able to find. Based on results using pip show modname, the modules were installed in: Anaconda3\lib\site-packages. In fact, as shown in Win Explorer, they are in sub folders under \site-packages, and there are 'regular' py files as well as compiled files. (I'm a beginner, and thought Python was interpreted?) I changed my system path variable to include: C:\Users\rba21\Anaconda3\lib\site-packages# Result: same error message C:\Users\rba21\Anaconda3\lib\site-packages\pyperclip # Result: same error message I tried adding the sub folders down to __pycache__ but got the same error message. I did some web searches, but didn't find anything that enabled me to fix the problem. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
