Im trying to start a django project from scratch but i have an error that says "ImportError: No Module Named 'pysqlite2'"
I'm using Python 3.6.0. I will write steps which im following
Creating project

What i tried?
- I installed sqlite3-dev with using sudo apt get ...
- I tried to install pip install pysqlite2
- I tried to alter source.py which is inside the virtual env folder but it wasnt worked.
But i figured out that when im not using virtual env, i mean without entering source /bin/activate, "python manage.py startapp demo" command has worked. When i activate env, it returns an error which i mentioned above.
according to this answer https://stackoverflow.com/a/23414147/2174832
There is no public version of pysqlite for Python 3.x. For Python 3.x,
the sqlite3 module in the standard library is the most up-to date
version of pysqlite there is.
run the command pip install sqlite3 within your activated virtualenv and use this module instead of pysqlite2. To activate your virtualenv go to /folderofvirtualenv/bin
and run the command source activate

I already create virtualenv here is my step:
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
$ brew update
$ brew install postgresql
$ brew services start postgresql
$ virtualenv env
$ source env/bin/activate
(env) $ pip install django psycopg2-binary
I has been used most people's solution: install psycopg2-binary not psycopg2 but still get symbol not found in flat namespace '_PQbackendPID'
My system environment：
macOS Monterey
Python3.10.7 64bit
asgiref==3.5.2
Django==4.1.1
psycopg2-binary==2.9.3
sqlparse==0.4.2
I has try to brew uninstall postgresql and install again it still have same issue, I'm afraid I'm doing something wrong or maybe I don't get how it work on Macbook M1.
Any help or explanation is welcome! Thank you.
try this
pip3 install psycopg2-binary --no-cache-dir
pip uninstall psycopg2
pip install psycopg2-binary --no-cache-dir
I installed the recent version of MySQL for my mac (macOS 12(ARM, 64-bit), DMG Archive) and created a database called storefront. I'm working in a pipenv virtual environment and install mysqlclient. I've also updated my DATABASES settings to point to my new database in my settings.py file.
DB Settings. But whenever I try to run the server I get an error. NameError: name '_mysql' is not defined Also at the top, (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e') I thought by installing the ARM version I wouldn't deal with this error. I wonder if it's pointing to the wrong file within my env despite adding the PATH to my .zshrc info. Is there a special way to point to the correct mysql or am I setting things up incorrectly? Here's my error message "

Error tell you, you have mysql macOs build for x86_64, but you should set up build for 'arm64e'.
here you can find both version for macOs:
https://dev.mysql.com/downloads/mysql/
I install mySql many times on macos... and now i have mariaDb
https://mariadb.com/kb/en/installing-mariadb-on-macos-using-homebrew/
For me it was easier to install
I'm running a django app with mariadb. It used to work just fine, however I have left this project idle for a while and now I'm just coming back to it and I can't figure out why it's now breaking.
I get the following error when trying to run python manage.py makemigrations:

Now I'll be honest. I may have a clue what the issue is. I'm not using a venv. And I have multiple installations on this system. The problem being I can't remember what I used for this project. I have python 2.7 and python 3. Python 2.7 runs Django 1.11 and python 3 runs django 2.2.7.
When I run manage.py in python 3 it returns the following:

Did you install mysqlclient?
Now this looks like a database error to me. But I have had this working just fine before with MariaDB. I even performed a full uninstall and reinstall of mariadb by the book from the install guides on the django page and the mariadb page. I'm really at a point of being stuck with this now. Can anyone point me in the right direction?
EDIT: I have tried solutions such as installing pymysql and such from other questions. But I do not seem to be able to find an answer so far

who can tell my what happend? Tkan you, a million time over. addtionally I wanted you know that I was a new guy in programming.

then try
pip install pysqlite
I'm trying to set up a Django app using a postgresql server (to eventually use with GeoDjango for GIS). I'm on a mac running OSX 10.11 and am running python 3.5 in a virtualenv. I've gone through all the installtion of postgresql, pyscopg2 etc and am trying to run
python manage.py migrate
But when I do I get the following error.

I've found a couple of stackoverflow threads on this error but none of the solutions seem to help at all.
Any advice would be much appreciated!
Edit: brew doctor output
Warning: python is symlinked to python3
This will confuse build scripts and in general lead to subtle breakage.
Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
/Users/me/.python3env/bin/python-config
Warning: Python is installed at /Library/Frameworks/Python.framework
Homebrew only supports building against the System-provided Python or a
brewed Python. In particular, Pythons installed to /Library can interfere
with other software installs.
