So I had this running yesterday when I was running the virtualenv out of my home directory. I've ran in to this problem a number of times now without a clear answer. I've done a lot of research on this but there seems to be no black and white answer. Today I moved my virtualenv to /usr/local/virtualenvs to better manage my projects and viola, it's broken again. Error loading MySQLdb module: No module named 'MySQLdb' is the bane of my existence right now. I can't seem to fix it this time. I have even tried duplicating what I did back into my home directory and have the very same problem. I haven't deleted any packages from my system. I installed the very same packages in the virtualenv. At this point I'm lost. I've even written down the steps I took from a fresh install to get to a working virtualenv. I certainly don't want to go back to a fresh install. Please help :)
Virtual Environment:
Ubuntu Server 16.04 LTS
python 3.5
django 1.10.2
pymysql 0.7.9

I am using Django for the first time but have used PostgreSQL previously. I am trying to follow the official Django tutorial to set up with a database. I have followed everything but I get an error when using the command "python manage.py migrate" that psycopg2 is not found even though I have it
installed.Traceback (most recent call last):

I am using the settings as mentioned in the Django tutorial:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': 'DatabaseName',
'USER': 'UserName',
'PASSWORD': 'Userpassword',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}
I have confirmed that I have the necessary packages installed and in the same location :
pip freeze:
Django==4.1.3
psycopg2==2.9.5
psycopg2-binary==2.9.5
pip show Django/psycopg2/psycopg2-binary:
Django : Location: /opt/homebrew/lib/python3.10/site-packages
Psycopg2: Location: /opt/homebrew/lib/python3.10/site-packages
psycopg2-binary: Location: /opt/homebrew/lib/python3.10/site-packages
It's seems like you use system python for running your migrations. Error traceback contains following path of python binary: "/Users/alexanderverheecke/Library/Python/3.9/...", however in pip show command your python path is "/opt/homebrew/lib/python3.10/".
Actually I don't understand how it's even possible, because first one looks like Windows path and the second one like Linux...
Anyway. Try something of this and run migrate command again:
activate/deactivate virtual environment if you use it
change your OS to the correct one
run pip install again
Make shure command which python(for Linux), gcm python (for Windows) returns the same python path as pip show.
I am using PyCharm on Windows 10 and using Python 3.8 - 64 bit and Django 2.2. pip install psycopg2 successfully installed psycopg2-2.8.5.
My database settings are as follows:
settings.py,
DATABASES = {
'default': {
'ENGINE': 'django.contrib.gis.db.backends.postgis',
'NAME': 'my-database',
'USER': 'my-user',
'PASSWORD': 'my-password',
'HOST': 'localhost',
'PORT': '',
}
}
my-user is the user that I am using and my-password is my password. However, python manage.py makemigrations causes a few errors as follows:

I am trying to get Django going with mySQL. I have started the app I can see all manage.py and other files. and in setting i changed:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'app',
'USERNAME': 'root',
'PASSWORD': 'root',
'HOST': 'localhost',
}
}
I have installed mySQL separately, I have XAMPP I started it but when I run:
python manage.py migrate
I get the following errors:

Did you install mysqlclient?
I didnt have this problem before, I think there are some different versions of Django or maybe the MySQL giving me problems.
I am using virtualenv and I have gone through many similar problems in Stackoverflow but no luck.
I have ran these commands:
pip install mysqlclient
sudo apt-get install python-mysqldb (command not found)
pip install mysql-python
still getting the same error.
Questions:
How can i remove all old versions of Django?
what is the solution for getting rid of this error?
I am setting up a web server for Python on Windows. While configuring settings.py, I changed the database to
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'db_name',
'USER' : 'root',
'PASSWORD' : '123456',
'HOST' : 'localhost'
}
}
I ran python manage.py makemigrations for verification of settings. It threw the following error:

Then I went to the Python 3 package index to install MySQLdb, but I did not find any supporting packages.
I have downloaded the "mysqlclient-1.3.7-cp27-none-win32" from the Python 3 package index. I installed it with pip install package_name. I even tried installing the wheel package before installing it, but nothing is working. How do I connect MySQL on Windows?
This installation error is coming with Python 3.5.1.
I had MySQL 5.5 installed as part of XAMPP stack on Win7 64bit. I am using python 3.4 and I want to try out Django. So I installed Django using pip from command line and it worked fine with the default sqlite3 db.
To integrate MySQL, I see installed 'mysql-connector-python' using pip. I changed the engine to ''mysql.connector.django'. I changed the settings.py file with the DATABASE settings as follows:
DATABASES = {
'default': {
'ENGINE': 'mysql.connector.django',
'NAME': 'db',
'USER': 'root',
'PASSWORD': '',

Try using 'django.db.backends.XXX', where XXX is one of:
'base', 'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'
Error was: cannot import name 'BaseDatabaseFeatures'
Found a bug filed here-
https://bugs.mysql.com/bug.php?id=76752
For resolution, it suggests-
Adjust the backend to the changes in Django API. See the release notes for details:
https://docs.djangoproject.com/en/1.8/releases/1.8/#database-backend-api
How do I adjust the backend? I have no idea how to proceed.
Installing from the forked version works.
pip install git+https://github.com/multiplay/mysql-connector-python
From Github repo description this one is
Fork of version 2.0.4 of mysql-connector-python (and probably rebased
at points) until upstream issues are fixed
Got the reference from bug url.
The latest version of mysql-connector-python works with Django 1.8. You can get it from the mysql website.
(version mysql-connector-python-2.1.3)
Install it from the MySQL:
pip install http://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-2.1.3.tar.gz
