django.db.backends.postgresql error when try to makemigrations my django project

I am trying to switch my Django database from SQLite3 to PostgreSQl, so I follow many tutorials to install and setup Postgres with Django project.
I did the following: pip install psycopg2, pip install psycopg2-binary and I modified the settings.py like that:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql',
'NAME': BASE_DIR / 'db.postgresql',
'USER': 'muusername',
'PASSWORD': 'mypassword',
'HOST': '127.0.0.1',
'PORT': '5432'
}
}
Finally I maked my database, by running the command python manage.py makemigrations.
However, I got this error:
django.core.exceptions.ImproperlyConfigured: 'django.db.backends.postgresql' isn't an available database backend or couldn't be imported. Check the above exception. To use one of the built-in backends, use 'django.db.backends.XXX', where XXX is one of:
'mysql', 'oracle', 'sqlite3'
Please note that I am also seccesufully install the pgAdmin in my OS which is Windows 10 in a first step.
I know that the problem is related by configuration of Postgres in my django project, but I don't know how to fix it, also I checked my djnago version which is the latest one, also, all needed packages are installed in my venv.

You cannot add like this in postgres:
'NAME': BASE_DIR / 'db.postgresql', #You got that error because of this. This setting is for only sqlite3 not for postgres
Just add db_name in NAME:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'your_db_name', #add your db name here
'USER': 'postgres',
'PASSWORD': 'your_db_password',
'HOST': '127.0.0.1',
'PORT': '5432',
}
}

Make sure you have actually downloaded the PostgreSQL installer itself and installed it.

I solve this problem by just upgrade the django, as you can see here in the exception:
django.core.exceptions.ImproperlyConfigured: 'django.db.backends.postgresql' isn't an available database backend or couldn't be imported. Check the above exception. To use one of the built-in backends, use 'django.db.backends.XXX', where XXX is one of:
'mysql', 'oracle', 'sqlite3'
Django ask the user to use mysql, oracle or sqlite3, but not the case of postgresql.
So this exception will be fixed when the user upgrade the django version.
I hope this answer can be helpful for someone another.

Django 2.1.5 on Windows. After runserver: System check identified no issues (0 silenced)

This message showed after I executed runserver command:
System check identified no issues (0 silenced)
I have referenced this solution, but it didn't work for me(I start my mysql server by the command
"C:\Program Files\MySQL\MySQL Server 8.0\bin\mysqld"
).
Here is the background information(the "pip list" command):
(DjangoEnv) D:\pythonproject\DjangoEnv\loginoutonly>pip list
Package Version
Django 2.1.5
mysqlclient 1.3.13
pip 18.1
PyMySQL 0.9.3
pytz 2018.9
setuptools 40.6.3
wheel 0.32.3
Here is the db information in settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'loginoutonly',
'USER': 'root',
'PASSWORD': 'pwd',
'HOST': 'localhost',
'PORT': '3306'
}
}

XAMPP helped me.
XAMPP says that
Port 3306 in use by "Unable to open process"!
I change my MySQL port to 3307 using XAMPP [Config] button.
Then, I change my settings.py code to
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'loginoutonly',
'USER': 'root',
'PASSWORD': '',
'HOST': 'localhost',
'PORT': '3307'
}
}
I also need to test the MySQL WorkBench connection of this newly connected port "3307".

Django won't make migrations with MySQL Database

I'm trying to make the migrations between my database (MySQL) and Django. I used the same parameters in Linux and didn't have any problems. Now I'm using the command :
python manage.py migrate
and I get nothing at all on the terminal. However, the command works if I let the default parameters ( for a sqlite database ). Also, I've noticed that it actually reads the 'settings.py' file because it returns an error if I write something that doesn't make any sense. Here are my parameters, I know for sure that they are correct ( I checked with the MySQL commands ).
settings.py
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'my_db',
'USER': 'root',
'PASSWORD': '123456789_dont_judge_me',
'HOST': '127.0.0.1',
'PORT': '3306',
}
}
Error message
I'm using Windows 10, Python 3.5 and Django 2.0.
Do you have any idea where the problem could come from ?
Thank you for your responses kind people !

You can try this.
Note: I am not claiming it is best solution, but it is working for me
in case of Window10.
Step1 : Install pymysql
pip install pymysql
Step2: Edit settings.py
settings.py
---------------
import os
import pymysql
pymysql.install_as_MySQLdb()
import MySQLdb
# Database
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django_test',
'USER': 'root',
'PASSWORD': '123456',
'HOST': '127.0.0.1',
'PORT': '3306',
}
}
Step3: migrate it
python manage.py migrate

django Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock

I have made a virtual environment and installed following:
sudo apt-get install libmysqlclient-dev
sudo pip install MySQL-python
and my setting is :
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB_NAME',
'USER': 'DB_USER',
'PASSWORD': 'DB_PASSWORD',
'HOST': 'localhost',
'PORT': '3306',
}
}
and when I do manage.py syncdb it gives the error saying 2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")
I dont know whats wrong in here...
I searched for it... Mostly I found if I use virtualenvironment then the above setting is enough... Whats wrong in here ???

Install mysql server
sudo apt-get install mysql-server
then create a database for your purposes:
mysql -u root -p --execute "create database DB_NAME; grant all on DB_NAME.* to DB_USER#localhost identified by 'DB_PASSWORD';"
then you should be fine.
I should point out that the confusion of mysql searching for a socket, even if specifying a port, is because mysql defaults to a socket when specifying localhost as an address, if you want to use tcp/ip then you should put an address like 127.0.0.1 there.

Your HOST should change to '127.0.0.1', you must start service, especially if you are using xamp or lamp.
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB_NAME',
'USER': 'DB_USER',
'PASSWORD': 'DB_PASSWORD',
'HOST': '127.0.0.1',
'PORT': '3306',
} #Your HOST should change to '127.0.0.1', you must start service, especially if you are using xamp or lamp

Django 1.4 + Apache WebServer + Mysql and PostgreSQL Connection Error

I have successfully followed the Django 1.4 Tutorial 1-4 (the poll system) and now its running until I deploy it in Apache Webserver 2.2 using Postgres Database. Everytime I access localhost I always have "Internal Server Error" but if I use MySQL as my database everything is ok. What do you think is wrong? Did I miss something to configure in Postgre?
Here is my database connection settings in Mysql(Working) and in Postgre(Not Working), both using Apache2.2 + mod_wsgi.so
//Postgre
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'django_demo1',
'USER': 'postgres',
'PASSWORD': 'mypassword',
'HOST': 'localhost',
'PORT': '',
}
}
//MySQL
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django_demo1',
'USER': 'root',
'PASSWORD': 'mypassword',
'HOST': 'localhost',
'PORT': '',
}
}
Other INFO:
OS: windows 7, Python: 2.7, Django: 1.4, Postgre 9.1

If you are able to access MySQL but not Postgres, I guess psycopg2 which is the Postgres adapter for python is not installed. Install psycopg2 using pip.
pip install psycopg2
Here is the pypi.
