Often requirements show up in requirements.txt like this:
django-registration
But in INSTALLED_APPS it appears as registration. So when you import like:
from registration.signals import user_registered
This is valid but PyCharm is showing a red squiggly line under the word registration in from registration... that says "Package 'registration' is not listed in project requirements".
How can I remedy this?
UPDATE
I was able to find a way to make the warning go away but it's not a good solution. If you simply add the package name to the requirements.txt file the warning goes away, but then that requirement is not valid if you were to install with pip. For example, I'm also using pygooglevoice which is how it's written in requirements.txt but when it's imported in the code, you write:
from googlevoice import Voice
This seems weird because I use PyCharm for many projects and I'm just noticing this with a recent project I'm working on...
After seeing this phenomenon again, I did some more digging. After setting certain folders as source roots and restarting PyCharm, these reference warnings went away. I think this is a bug in PyCharm.
This seem to be an open issue
https://youtrack.jetbrains.com/issue/PY-11963
JetBrains claims that this is fixed in version 2017.2:
https://youtrack.jetbrains.com/issue/PY-11963#comment=27-2248728
I can confirm this (in IntelliJ IDEA). Also, it's worth double-checking that the correct requirements file is specified in Settings -> Tools -> Python Integrated Tools -> Package requirements file
PyCharm should be able to figure this out, but it doesn't. For now, I just add # noinspection PyPackageRequirements to each import with this warning to suppress it. I'd rather not, but it works for now.
This issue can be fixed using the following commands in the terminal (using linux, not sure if this will work on windows, but I see no reason why it shouldn't, I haven't tried on windows.)
If you haven't created a requirements.txt file already
touch requirements.txt
This should do the trick
pip freeze > requirements.txt
pip install flask
For better understanding, I recommend reading this

This question is not a duplicate of this question, because I am trying to create an app.
I am currently following this tutorial, but when I try to run my app,
my command prompt prints out this error:
Why does this error happen and how can I solve it? I read through all the answers to the linked question, but none of them are pertinent to my problem.
Please anyone help me, I still haven't found a working solution; I am getting desperate!!!
Edit: I can't just install and uninstall pynput? Idk why it doesn't work because shouldn't pynput come with idle?
Version: 3.74 python idle, most updated version of pyinstaller
The following might help you if you haven't tried them already:
Update pip from the command line
Unistall pyinstaller
Re-install pyinstaller and try it again
If the above does not work, try running the following command in the command line. Make sure there are some print statements in your code to see if it works.
python monitoring_culmination_product.py
If you got a message saying "python is not recognised as an internal or external command" then python might have not been added as an environment path.Try this to fix the issue.
You could always re-install python if things get difficult.(make sure you install the appropriate version 32-64bit)
If the command though executed without a problem. Try to use pyinstaller on another file to see if the problem has to make sure the problem has to do with pyinstaller.
From a personal experience, pyinstaller can be unreliable at times so I put the following line in my projects just to make sure. It might help you too.
import pkg_resources.py2_warn
Disclaimer: Although it is not specified I assume that you are using Windows
You could try to use conda create to get an environment containing all the need dependencies (numpy, etc) and then use pyinstaller as explained in this discussion.
Please fall back to 1.6.8 version of pynput. pip install pynput==1.6.8

Okay, so, I'm actually a beginner in programming Python, and I only found out yesterday how you were supposed to encode pip install ModuleName in the Python command line and not in the interactive shell. I'm trying to download a lot of modules, such as the Send2Trash module, Pyperclip, Requests, Beautiful Soup, and Selenium.
Before I checked the forums about installing modules, I found out how we needed to have the pip tool. I'm a Windows user, but for some reason, I didn't have the 'Scripts' folder installed when I downloaded Python. I didn't know we needed it, so I used raw scripts from GitHub, setup.py, and copy pasted the script into the File Editor in Python, ran it in the interactive shell, and tried to import the module I needed. It worked for the Pyperclip and the Requests module; no errors popped up after I imported them using import pyperclip or import requests, but when I tried the same procedure for the rest of the modules I needed, there were some errors.
Also, when I tried to download the modules on pypi.python.org, I tried to open it using the interactive shell, but then something pops up, 'The file's encoding is invalid for Python3.x...', and when I click 'OK', it's going to say 'Failed to Decode', and close everything.
So, after reading forum after forum, I found out how to download pip, and was also able to download setuptools and wheel. I'm not sure if it's really already downloaded, but I was able to get the 'Scripts' folder that wasn't there before, so I guess so. I also already went into my PATH using the edit environment for your account thing, and I edited the Path variable so its value would lead to my 'Scripts' folder. Please do tell me if I did the right thing here.
So, following the advice of the forums, I tried to install the modules I needed by typing pip install ModuleName in the Python command line instead of the interactive shell, but it still gave me a Syntax Error. I also tried it in Command Prompt, typing the same code pip install ModuleName, but when I clicked Enter, nothing happens; no errors or anything. It seemed like my install was accepted, but when I tried importing the module in the interactive shell, it still gave an Import Error.
Please tell me what I did wrong throughout my process, and how to properly install the modules I need. I would include pictures into this, but it seems I can only add two before my reputation becomes 10, and I'm pretty new here, so... If there's anything I need to elaborate on about my problem, don't hesitate to ask, and I'll try my best.
You say you use windows so you need to understand pip.
pip is a program that installs python modules. You can even use easy_install instead of pip.
some pip commands
pip list -- lists out already installed modules.
pip search <module name> -- searches new modules.
pip -h -- more pip commands you want.
pip installs modules from CMD prompt not from python shell.
Even after installing modules some modules doesn't run as import module
they need to be imported as from module import function.
refer the pip help command and install modules.
DO NOT SAVE SCRIPT FILES IN PYTHON ROOT FOLDER YOU MAY FACE SOME PROBLEMS
Happy Programming!!!
After a whole lot of searching and trying out, I found the solution to my problem. For future Python users who encounter the same thing: always install your modules in the root folder.
In my case, my Command Prompt was automatically inside the C:\Users folder, which caused some problems because I couldn't download my module in there. Once I typed in cd C:\Python34, which was my root folder, I could successfully download the modules I needed using pip install ModuleName.
I've just started looking into python and django.. Im pretty sure ive successfull installed both python and the django framework and i managed to add python and django-admin.py to my system path but now when i run the command django-admin.py startproject My_Test_Site, in the folder i want to create a new project directory in (just following the tutorials), i get the following error:
What am i doing wrong?
This is not a Django error. It appears it cannot find the Python module unicodedata which is part of the Python Standard Library (docs). I see that there is also a bug report about this issue (Python 2.7 on Windows, see here). On the other hand, some people there report that reinstalling their Python installation fixed the problem. You could give that a try.
notice the last line, it says import unicodedata, importError
im guessing you probably didnt install your django properly.
so reinstall it and check that django is in your "path", i believe django does this automatically when it installs but doesnt hurt to double check.
if reinstalling django still doesn't work, i suggest you uninstall python and django related stuff.
then install python, install pip, then use pip install django.
I was following the directions at http://django-dajaxice.readthedocs.org/en/latest/installation.html to install Dajaxice for simple AJAX support and I ran into an error I can't quite figure out. The lines:
from dajaxice.core import dajaxice_autodiscover
#dajaxice_autodiscover()
in urls.py seem to be causing an error (cannot import name dajaxice_autodiscover). When I look at the module files for Dajaxice I don't see one for autodiscover either. If I leave out these lines, will I have any troubles using dajaxice? Thanks.
The import should be correct like that! dajaxice_autodiscover imported in __init.py__ of the core package, so it is supposed to work like that! More likely the whole app is probably installed in a wrong path, you could try to open a shell (python manage.py shell) and try import dajaxice and see what happens!
William What version of dajaxice do you have? the "registration approach" documented in github wiki work with dajaxice>=0.1.5
For older versions of dajaxice you should register your functions in settings.DAJAXICE_FUNCTIONS.
Anyway newest versions of dajaxice has less bugs.
It looks like the wiki installation instructions are ahead of the available downloads. If you pull the latest version of the code from git and install that then the instructions work. I'm not sure how to install versions 1.4 and below though.
I experienced the same problem and I found the solution.
It all about environment vairables in windows. You set following via CMD:
set DJANGO_SETTINGS_MODULE 'Your django project/your site/settings.py
Now it should work fine, Good Luck!
Upon trying to start a Pinax app, I receive the following error:
Error: No module named notification
Below are the steps I took
svn co http://svn.pinaxproject.com/pinax/trunk/ pinax
cd pinax/pinax/projects/basic_project
./manage.py syncdb
Any suggestions?
UPDATE:
Turns out there are some bugs in the SVN version. Downloading the latest release solved my problem. If any one has any other suggestions on getting the trunk working, they would still be appreciated.
I'd avoid the svn version all together. It's unmaintained and out of date. Instead, use the git version at http://github.com/pinax/pinax or (even better) the recently release 0.7b3 downloadable from http://pinaxproject.com
Two thoughts:
1. Check all of your imports to make sure that notification is getting into the namespace.
2. You may be missing quotes around an import path (eg. in your urls.py: (r'^test', 'mysite.notification') -- sometimes I forget the quotes around the view)
Try following the latest install instructions here:
http://github.com/pinax/pinax/blob/600d6c5ca0b45814bdc73b1264d28bb66c661ac8/INSTALL
Don't think this will work on Windows (maybe if you are using cygwin) as they are using virtualenv and pip.
Note the version has recently been upgraded to 0.7rc1
IIRC I had to add a directory or two to the Python path last time I did a fresh install of Pinax. I'm doing a fresh checkout now into a new virtualenv, I'll edit this answer if I hit any snags.
