I'm writing a simple test for Android app and it fails while trying to connect my device with this log:
Traceback (most recent call last): File "D:/MonkeyRunnerTest/test/LaunchTest.py", line 3, in <module>
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice ImportError: No module named 'com'
I use Pycharm 2.7.3, Python 3.3.2, juthon-standalone-2.5.3. I've tried to launch my test project on Eclipse with PyDev and Intellij Idea with Python plug-in, but with the same result. Also I've added environment variable PYTHONPATH containing the path to monkeyrunner and jython source to my operation system (Windows 7), it didn't help.
Any suggestions for this issue?
You should only use monkeyrunner interpreter to run monkeyrunner scripts. Forget about python, jython, etc.
From you command line try:
monkeyrunner LaunchTest.py
and it will work.
You can find some instructions to use monkeyrunner with Eclipse+Pydev. See the updates at the bottom of the page.
Assuming you have the proper modules installed: They aren't in your system path. You can check your system path manually to see if the directory is there by doing
import sys
print sys.path
You can append to sys.path as you would any list, but it's probably better to modify it via your OS, rather than on the fly appending. (which is temporary, sys.path reverts to its original state after the end of the script in python)

I am working on a Python project in Pycharm (2020.1.2) on Windows 10.
For this project, I cannot use the standard Python interpreter, I have to use my own located at C:\some\path\here\python\27_64\python.exe (Python 2.7.3).
Backstory may be important:
I have added this path to the system path for both myself and all users, and placed it ahead of %LOCALAPPDATA%\Microsoft\WindowsApps to try to prevent the Microsoft store from popping up whenever I try to run python on the command line - however I don't feel like this change to the path variable has made a difference, as the Microsoft store still pops up.
I can start a Python shell by running C:\some\path\here\python\27_64\python.exe, so I know it technically works. When I do so; the sys.path is as follows:
['', 'C:\\another_place\\Python_2.7.3_x64\\python27.zip',
'C:\\some\\path\\here\\python\\27_64\\DLLs',
'C:\\some\\path\\here\\python\\27_64\\lib',
'C:\\some\\path\\here\\python\\27_64\\lib\\plat-win',
'C:\\some\\path\\here\\python\\27_64\\lib\\lib-tk',
'C:\\some\\path\\here\\python\\27_64',
'C:\\some\\path\\here\\python\\27_64\\lib\\site-packages']
Anyway, when I try to run a Python console (not even my script), this is the message I get in Pycharm:
C:\some\path\here\python\27_64\python.exe "C:\Program Files\JetBrains\PyCharm 2020.1.1\plugins\python\helpers\pydev\pydevconsole.py" --mode=client --port=59771
Traceback (most recent call last):

import _socket
ImportError: DLL load failed: The specified procedure could not be found.
Process finished with exit code 1
I have gone to Settings>Project:[name]>Project Interpreter and set it to C:\some\path\here\python\27_64\python.exe (and rebooted Pycharm to be sure). That said; in the settings window no packages are shown and it claims that Python packaging tools can not be found.
When I click the link to install them (circled in red), they can not be installed due to this error:
ImportError: cannot import name _remove_dead_weakref
Are there other variables or settings I need to change?
Thanks
EDIT
Uninstalling the first Python on my Path (C:\\another_place\\Python_2.7.3_x64\\python27.zip) just makes everything so much worse
EDIT 2
I added the PATH variable manually to both the Python console settings and to the Run/Debug settings in PyCharm (and restarted the program), the result is still the same
I had a similar issue. This procedure fixed my issue.
Try the following:
run print(os.environ['PATH']) in the system terminal using the same interpreter
copy the result and add as PATH environment variable to your Run/Debug Configuration
do the same for Python Console settings
I hope it will work.
It seems that the interpreter is not being recognized by the windows as a result of which you are unable to install packages.
Also, I suppose the interpreter should be present in the bin folder of your python folder. The interpreter does not have a .exe extension.
I would suggest installing anaconda python 2.7 64 Bit windows package installer and using the condo environment and work on python 2.7
Here is a link I found for Python 2.7 on Windows hope this helps:
https://docs.python.org/2/faq/windows.html
Had the similar issue, in my case it was always trying to find libraries in PostgreSQL installation directory.
Mentioning sys.path helped me here! I tried printing it from inside my script and realized that PostgreSQL directories appear earlier in the list than Python directories.
SO, how I finally fixed it -- added PYTHONPATH environment variable to my Run configuration in PyCharm like this (replace with paths to your Python installation directory):
PYTHONPATH=D:\PROGRAMS\Python\Python3.9\DLLs\;D:\PROGRAMS\Python\Python3.9\lib\;D:\PROGRAMS\Python\Python3.9\;D:\PROGRAMS\Python\Python3.9\lib\site-packages
This helps to put desired directories at the beginning of the list, thus they are searched first and required libraries are found as it is supposed to work.
I am pretty new to python, interpreters, and programming in general. I script my .py files in pycharm. As you probably know pycharm copies the default interpreter to every project. When I install external libraries I install them at the project interpreter, not at the main interpreter. That works well during the pycharm development phase, but when I try to run the script outside it, it runs it with the default interpreter ( without the newly downloaded libraries ). How can I change that every script uses his own interpreter?
I don't want to download all these libraries to the default compiler and I don't want to change the default library every time I run another script ( via variable editor ).
Also I don't want ro run all my files using pycharm everytime ( since it's quite resource consuming and it takes a while )
I haven't tried anything yet, I couldn't find info about this.
When running without pycharm:
Traceback (most recent call last):
File "C:\Users\Andrei\PycharmProjects\mcdis\mcdis.py", line 1, in <module>
import discord
ModuleNotFoundError: No module named 'discord'
PS: The OS is Windows 10.
I found a shortcut:
Using a shebang ( a line of 'code' that specifies the interpreter which should be used ). While virtual environments seem to have some advantages the shebang trick should do it for most of the scripts.
How to use a shebang :
#!"C:\Users\Andrei\Desktop\MCSERVER\venv\Scripts\python.exe"
Just tell the path to the interpreter with a '#!' in front. Not sure if it works with relative path but I think it does.
I downloaded the nltk package from https://github.com/nltk/nltk_data (I cannot use nltk.download() due to proxy issues) and put it at C:\nltk_data. When I try 'import nltk' from the python interpreter I get this error message:
Traceback (most recent call last):
File "", line 1, in
ImportError: No module named nltk
I do not know how to get the python interpreter to see the folder. Any help would be greatly appreciated.
Thanks!
In my opinion, the Python interpreter will check the library path before its running.
You can use sys.path in python interpreter to check the place.
Always by default, python will add the running path to the library path which in linux like "./".
If you want to run the python in another path, In Windows there are two ways to solve this problem.
You can add a environment variable
C:\Users\Administrator>set PYTHONPATH=C:\nltk_data
Or you can add it in you python script like:
sys.path.append("C:\nltk_data")
PS:
Dobule check the path(\ or /) which is in different types between Windows and Linux.
I have a python3 script that I am calling in terminal; I do not use Python prefix to run it, since I did add #!/usr/local/bin/python3 in my script (I have python3 from brew, on OSX).
The interesting thing is that if I run the script in terminal, I get an import error because one of my custom module hasn't been found. If I run the same script in pycharm, it works fine.
I assume Python launch and read all the various path that I use for modules in the same way, in both pycharm and terminal, but it seems not the case. How do I set up my scripts so the modules are found, independently from their path?
I may run the same script from other machines too, so I want to be prepared and do the right thing from the start.
EDIT
I am running pycharm on OSX; Python3 is installed via Brew, but the symlink is in /usr/local/bin.
My script is running from a folder inside my home directory, so
/Users/tester/git/python_test_app/main/base/app_main.py
The custom modules are in the same folder of the main py script, but one level above: /Users/tester/git/python_test_app/main/pyutils.py
The import statement from app_main.py is
import main.pyutils as utilities
This is the stack trace that I get when running the script:
Traceback (most recent call last):
File "main/base/app_main.py", line 13, in <module>
import main.pyutils as utilities
ModuleNotFoundError: No module named 'main'
EDIT 2 and solution
Thanks to The answers, I was able to figure out that the issue is related to how Pycharm handle projects. Basically it somehow save the path where the project is; so calling an import will result in the project folder being parsed, and that's why it works fine from Pycharm.
In Python, unless PYTHONPATH has the path to my project or other modules that I wrote, it won't be able to find them, hence, raise the error.
FIX:
in my main module that I use to run the application, I did retrieve the path of the file; which I know being one level below the modules I need; so I can explicitly add the folder to the current sys.path. This will end up making possible for me to call the import successfully.
import sys
current_dir = os.path.dirname(__file__)
sys.path.insert(0, , current_dir)
The only downside is that every file and resource that I use in my project, has to be directly referred by full path; so I have to pass the current_dir around the various files in the project.
PyCharm has project interpreter settings. Verify these are the same as your system Python. Go to:
File menu
Settings
Project: <project name>
Project Interpreter
View the path to the Python executable/binary being used by the project in PyCharm and verify it matches what your system is calling (e.g., which python3)
Alternatively, it may be that you declared your sources root within PyCharm and the system cannot properly run the module as it exists in the path you're running it from (especially if inside a package). You can get around this using the -m parameter and calling it from Python.
You can also try running it from the Terminal inside PyCharm and see what it adds to the path before initializing the shell session (you can sometimes see this in your Run configurations also). If you are referring to modules not installed via pip / into the Python path but rather loaded into your project path, then this may be the culprit.
On PyCharm, next to the green "RUN" arrow press the box and then press edit configurations (see image)
There you'll have Working Directory - that path is where PyCharm is running that script from (without errors).
Try running it from the terminal within that path - that should solve your import errors.
I am unable run interpreter in Eclipse. I made a new interpreter which is loading python2.7 from the Virtual environment.
When i run the manage.py file it is giving me error, as it is unable to load the module.
It works fine if I am executing it from terminal, but it gives me error when i run the command from eclipse.
Error:
Traceback (most recent call last):
File "/home/workspace/tms/manage.py", line 8, in <module>
from django.core.management import execute_from_command_line
ImportError: No module named django.core.management
Am i facing this problem because of Ubuntu 11.0, or is there some other problem ?
Can anyone pls help me..
It sounds like your interpreter isn't properly set up. I would suggest configuring a new one. When you select the location of your new interpreter make sure you use the python executable from within your virtualenv (not the system one), that's probably /path/to/your/virtualenv/bin/python.
When you get to the point where eclipse invites you to add folders to your python path, it's proably easiest just to click 'select all'. This should include all the packages (eg django) from your virtual env.
Then use this new interpreter on your project and eclipse should be able to find the django.core.management module (and all the other modules used in your project).
