I have been at this for a day and have found no solution. My python project is very levels deep and some of the modules have to be run independently (no -m flag, no relative imports). For this reason we decided to add the root folder to the PYTHONPATH. I am running OSX 10.11.3. Everything had been running smoothly until yesterday. I could run independent modules from the terminal with no issues in both Python 2.7 and 3.5. Yesterday, without modifying my PYTHONPATH or any other environment setting, running any of these independent modules from the terminal now gives me import errors in both Python 2 and 3.
Here is my working tree:
/Users/sintrafico/Documents/code/central_maestra
- reports_server.py
- api_server.py
- sintrafico
- sql
- SQLConnection
- api
- incident
- csv (not package)
- independent_module
- tests
I was running my tests yesterday with coverage with no problem, but now I can't.
Python 2 python csv/independent_module.py gives error:
Traceback (most recent call last):
File "csv/independent_module.py", line 13, in <module>
from sintrafico.sql import SQLConnection
ImportError: No module named sintrafico.sql
Python 3 python3 csv/independent_module.py gives error:
Traceback (most recent call last):
File "csv/create_bemobile_csv.py", line 13, in <module>
from sintrafico.sql import SQLConnection
ImportError: No module named 'sintrafico'
From within the incident folder, yesterday this command was working fine: coverage run -m unittest discover. Now all the tests fail because ImportError: No module named 'reports_server'.
Since that started happening yesterday, I have been messing with my PYTHONPATH. I left it blank and it didn't work (as expected), I have added the path now several ways:
export PYTHONPATH=“${PYTHONPATH}:/Users/sintrafico/Documents/code/central_maestra"
export PYTHONPATH=“/Users/sintrafico/Documents/code/central_maestra:${PYTHONPATH}"
export PYTHONPATH=“${PYTHONPATH}:/Users/sintrafico/Documents/code/central_maestra/"
export PYTHONPATH=“/Users/sintrafico/Documents/code/central_maestra:${PYTHONPATH}"
And also setting it without appending the PYTHONPATH since it was empty to begin with. I restarted my computer several times with no success. Also note, I have a .bash_profile and .bashrc with the following contents:
# Setting PATH for Python 3.5
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.5/bin:${PATH}"
export PATH
PYTHONPATH=“/Users/sintrafico/Documents/code/central_maestra:${PYTHONPATH}“
export PYTHONPATH
And lastly, what bugs me the most is that if I run the tests inside PyCharm they all run and pass, I get no import errors at all.
Have you tried setting the path without the quotes and braces? You are setting the python path as a string representation of the path instead of a list of paths

I know there has been similar problems, but unfortunately most of them are related to errors with pyperclip itself instead of the batch file, which i suspect is where the problem stems from.
Below is an MRE of my Python script:
#! python3 -> Do I have to use my version(3.8)?
# pw.py - An insecure password locker program.
import sys, pyperclip
#do something with the module
And my batch file pw.bat:
#py.exe C:\Users\KEVIN\PycharmProjects\atbs_exercise\pw.py %*
#pause
I am running python 3.8 on windows 10. I imported the pyperclip module in my python script pw.py and ran the file via pw.bat, and this in turn gives me this error:
Traceback (most recent call last):
File "C:\Users\KEVIN\PycharmProjects\atbs_exercise\pw.py", line 7, in <module>
import sys, pyperclip
ModuleNotFoundError: No module named 'pyperclip'
Press any key to continue . . .
Which shouldn't happen as I have installed pyperclip on the project using pip, and the script itself runs just fine in pycharm. What am I missing?
EDIT: I forgot to mention that I am using pycharm. So the thing is that pycharm had also installed python.exe in the project folder. And as the module pyperclip is only installed to that folder, the python.exe used in the bat must point to the one in the project folder.
i don't know why are you using py.exe. when running commands from a batch file or cmd .you should use python.exe.obviously you would need to add python to add for doing so.instead of adding py.exe to path,add python in system variable Path which is somewhere present in C:\Users\[username]\AppData\Local\Programs\Python\(your path might be diffrernt).you can add python in Path by following this post
after adding python to path just use the following batch-file:
#echo off
python path-to-your-py-file\filename.py
I am trying to run a python pipeline through Mac OS Terminal. I am using Python 2.7.15 because newer versions of Python gave me error messages with this file. I keep getting the following error message:
$ python ../../../scripts/gemmaPipeline.py ../../../data/all.fixGL.Q10.ap.bi.MAF5.vcf.gz outfile Results
Traceback (most recent call last): File
"../../../scripts/gemmaPipeline.py", line 5, in
import utils, vcf, genomes100, gemma ImportError: No module named genomes100
The modules listed in the import command are present under the "scripts" folder in a subfolder "modules". For each of the four modules, I have a .py and .pyc file in this subfolder. I cannot get Python to find this path.
I have tried running the same script within a virtualenv but to no avail. I even tried moving the "modules" subfolder to the Python "site-packages" folder in hopes that it would work but failed.
Finally, I tried including an init.py file (blank) in the "script" folder, but that didn't work either.
I am an utter novice and am pretty much learning as I go.Please help.
I have an annoying problem with PyCharm CE and naoqi. Following the installation instructions in Aldebaran Guide, I have configured my environment to work with this one.
I have installed the version of python (python 2.7.13) suggested by Aldebaran, I have written the .bash_profile using:
# Setting PATH for Python 2.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
export PATH
#NaoQI 2.5.5
export PYTHONPATH=${PYTHONPATH}:/Users/francesco/Documents/PyLibs/pynaoqi-python2.7-2.5.5.5-mac64/lib/python2.7/site-packages
export DYLD_LIBRARY_PATH=${DYLD_LIBRARY_PATH}:/Users/francesco/Documents/PyLibs/pynaoqi-python2.7-2.5.5.5-mac64/lib
after that, I launch my code in python from Terminal (making sure that the right version of python is called when I type
$ python my_code.py
and all is working (I tried also with virtualenv and all works fine if I launch all from terminal).
So far so good but then comes the poison arrow. I use PyCharm CE like IDE, I have created a new project that use the same environment that works fine in terminal and the magic happens..
The first issue is:
/Users/francesco/Documents/PyEnv/pynaoqi255_python2713/bin/python /Users/francesco/PycharmProjects/PepperRobot/PepperRobot.py
Traceback (most recent call last):
File "/Users/francesco/PycharmProjects/PepperRobot/PepperRobot.py", line 5, in
import qi
ImportError: No module named qi
(Ok seriuosly this is the same environment that in terminal works)
I try to bypass the problem, adding the content of naoqi sdk in the virtualenv's site-package. Ok, the problem is bypassed.. But there is another problem:
/Users/francesco/Documents/PyEnv/pynaoqi255_python2713/bin/python /Users/francesco/PycharmProjects/PepperRobot/PepperRobot.py
Traceback (most recent call last):
File "/Users/francesco/PycharmProjects/PepperRobot/PepperRobot.py", line 5, in
import qi
File "/Users/francesco/Documents/PyEnv/pynaoqi255_python2713/lib/python2.7/site-packages/qi/init.py", line 88, in
from _qi import Application as _Application

Referenced from: /Users/francesco/Documents/PyEnv/pynaoqi255_python2713/lib/python2.7/site-packages/_qi.so
Reason: image not found
Process finished with exit code 1
I did not understand why...
I have also include in
Preferences -> console -> Python Console -> Environment Variables
the same variables included in .bash_profile but to no avail.
How can I solve this tedious problem ?
I have solved my problem editing run/debug configuration and putting here the environment variable DYLD_LIBRARY_PATH. All works fine.
PyCharm 2016.2.3, Mac OS X 10.11.1, Python 3.5 (Homebrew);
I have this folder structure
project
/somepackage
/subpackage
__init__.py
bar.py
__init__.py
foo.py
foo.py:
import somepackage.subpackage.bar
print("foo")
bar.py:
print("bar")
So my expected output is
bar
foo
This works fine when run from PyCharm. However, when I run it from my terminal I get an ImportError:
$ pwd
$ /home/project (not the actual path; just omitting some personal stuff)
$ python3.5 somepackage/foo.py
File "foo.py", line 1, in <module>
import somepackage.subpackage.bar
ImportError: No module named 'somepackage'
I have found this question, which is about the same problem. However, none of the suggested solutions work for me, as I am indeed using the same Python interpreter as PyCharm does and I am currently in the folder that contains the /somepackage folder.
Does anyone have any other suggestions about how to solve this issue?
You are running foo.py like a script, but you are really using it like a module. So the proper solution is to run it as a module:
python3 -m somepackage.foo
For the record, another alternative is to edit your path like:
export PYTHONPATH=.
(Or you could put the absolute directory in there, and of course you should append any other directories that are already in your PYTHONPATH.) This is closer to what PyCharm does, but is less philosophically correct.
Setting PYTHONPATH is what makes it work, as noted above. I use the following VSCODE .env content so that it works for any project:
PYTHONPATH=${PROJ_DIR}:${PYTHONPATH}
This is essentially what PyCharm does when you check "Add Content Roots to PYTHONPATH" in your run/debug configuration. It's a helpful setting, but it spoils you because your code fails outside PyCharm.
Or, if you run in terminal, first export:
export PYTHONPATH=...
Took me days to work all this out.
i solved my problem by two steps on Linux:
first step
go to the root directory of your project and set:
export PYTHONPATH=$PATHONPATH:`pwd`
second step
run python3 -m somepackage.foo
remember Without '.py' suffix
I just had the same problem using scapy.layers.http Module,
this problem occurred on my Kali (linux-Debian) but run fine on Win-10 (after few modifications.)
packet was installed (scapy-http) correctly and the program was running in PyCharm but not as script (from terminal)
I tried solving it with reinstalling in main root, and messing with the sys.path but None have worked.
Troubleshoot & Solution
I found that it looks for the http module in:
/usr/local/lib/python3.7/dist-packages/scapy/layers/init.py
and got the ImportError:
from scapy.layers import http --->
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: cannot import name 'http' from 'scapy.layers' (/usr/local/lib/python3.7/dist-packages/scapy/layers/__init__.py)
So then I checked where scapy-http is really installed, which is module called http.py, so I just copied it to:
/usr/local/lib/python3.7/dist-packages/scapy/layers/
found the http.py file in :/usr/local/lib/python3.7/dist-packages/scapy_http/
And that did it :)!
I know its a bit glitchie but that worked!
The problem:
I have a Jenkins build step that executes a shell script. This script in turn calls a python script which is performing some cryptographic functions. However when the build executes, I am getting the following error.
Traceback (most recent call last):
File "./xyz.py", line 4, in <module>
import rsa
ImportError: No module named 'rsa'
The Jenkins' node has two versions of python - 2.7 (default) and 3.4 and rsa is installed for both of them. I even ran the script (using version 3.4) on the slave itself and it worked fine.
What I have done so far:
I am using EnvInject plugin to point PYTHONPATH to correct location. Without it, I found that PYTHONPATH was undefined.
With Python 2.7
Using default version, my script starts with: #!/usr/bin/env python
Jenkins output:
[EnvInject] - Executing scripts and injecting environment variables after the SCM step.
[EnvInject] - Injecting as environment variables the properties content
PYTHONPATH=/usr/local/lib/python2.7
[EnvInject] - Variables injected successfully.
[demo] $ /bin/sh -xe /tmp/hudson9217742060700174209.sh
+ export PYTHONPATH=/jenkins/workspace/demo:/usr/local/lib/python2.7
+ echo /jenkins/workspace/demo:/usr/local/lib/python2.7
/jenkins/workspace/demo:/usr/local/lib/python2.7
+ ./abc.sh
/usr/bin/env: python: No such file or directory
With Python 3.4
The Shebang in this case is #!/usr/bin/env python3
Jenkins output:
[EnvInject] - Executing scripts and injecting environment variables after the SCM step.
[EnvInject] - Injecting as environment variables the properties content
PYTHONPATH=/usr/local/lib/python3.4/

+ echo /jenkins/workspace/demo:/usr/local/lib/python3.4/
/jenkins/workspace/demo:/usr/local/lib/python3.4/
+ ./abc.sh
Traceback (most recent call last):
File "./xyz.py", line 4, in <module>
import rsa
ImportError: No module named 'rsa'
I even tried doing sys.path.append(os.environ['/usr/local/lib/python3.4/dist-packages/rsa']) in the script itself, but the problem persists.
Can anyone help me with this issue? Thanks.
P.S.- My knowledge of Python is very limited.
As far as I can remember it, I had similar problems with my Python-script and I finally solved it by using
python xyz.py
instead of
./xyz.py
Unfortunately I can not explain why it works in this way, but not the other, but in my case it solved the problem.
