The problem Im facing while trying to connect to database for mysql. I have also given the database settings that i have used.

Thanks a lot for the help !!
Seems like you don't have permission to the Python folder. Try sudo chown -R $USER /Library/Python/2.7
For Ubuntu 16.04 and 18.04 or python 3 versions
sudo apt-get install python3-mysqldb
You are missing the python mysqldb
library. Use this command (for Debian/Ubuntu) to install it:
sudo apt-get install python-mysqldb
It is because it did not find sql connector. try:
pip install mysqlclient
Just to add to other answers, if you're using Django, it is advisable that you install mysql-python BEFORE installing Django.
When I set up Django development environment for PyCharm in Mac OS X Mountain Lion with python, mysql, sequel pro application I got error same as owner of this thread. However, my answer for them who is running python-mysqldb under Mac OS Mountain Lion x86_x64 (MySql and Python also should be same architecture) and already tried everything like pip and etc. In order fix this problem do following steps:
If you get error something like this: "Environment Error: /usr/local/bin/mysql_config not found" then try to add path ass follows: "export PATH=$PATH:/usr/local/mysql/bin". But id did not helped to me and I found another solution. In the end of command execution error output which looks like this:
File "/path_to_file/MySQL-python-1.2.4b4/setup_posix.py", line 25, in mysql_config raise EnvironmentError("%s not found" % (mysql_config.path,))
Open setup_posix.py with vim and go to line 25 (In your case it can be different unless if it is same version).
Line 25 should look like this after your editing unless your mysql have symbolic link like follows '/usr/local/mysql/bin/':
f = popen("%s --%s" % ('/usr/local/mysql/bin/mysql_config', what))
After this I got another error as following:
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: dlopen(/Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib Referenced from: /Library/Python/2.7/site-packages/MySQL_python-1.2.4b4-py2.7-macosx-10.8-intel.egg/_mysql.so Reason: image not found
Finally I did following in console:
sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib
Currently everything works fine. So I hope it will be helpful for somebody who uses Mac. :)
With the same error message as Will, it worked for me to install mysql first as the missing file will be added during the installation. So after
brew install mysql
pip install mysql-python
ran without errors.
I've solved this issue in this environment:
$ pyenv --version
pyenv 1.2.9
$ python --version
Python 3.7.2
$ python -m django --version
2.1.7
./settings.py
DATABASES = {
'default': {
'NAME': 'my_db_name',
'ENGINE': 'mysql.connector.django', # 'django.db.backends.mysql'
'USER': '<user>',
'PASSWORD': '<pass>',
'HOST': 'localhost',
'PORT': 3306,
'OPTIONS': {
'autocommit': True,
},
}
}
If you use 'ENGINE': 'mysql.connector.django'
, install driver executing:
$ pip install mysql-connector-python
Successfully installed mysql-connector-python-8.0.15 protobuf-3.7.0 six-1.12.0
Note that $ pip install mysql-python
didn't work for me.
Note that if you use 'ENGINE': 'django.db.backends.mysql'
, you should install driver executing:
$ pip install mysqlclient
Finally execute:
$ python manage.py migrate
If it's all right, python creates all these tables id database:
auth_group
auth_group_permissions
auth_permission
auth_user
auth_user_groups
auth_user_user_permissions
django_admin_log
django_content_type
django_migrations
django_session
Maybe you can try the following mode of operation:
sudo python manage.py runserver 0.0.0.0:8000
I was having the same problem.The following solved my issue
Run pip install pymysql in your shell
Then, edit the init.py file in your project origin directory(the same as settings.py) and then
add:
import pymysql
pymysql.install_as_MySQLdb()
this should solve the problem.
I think it is the version error.
try installing this in following order:
sudo apt-get install python3-mysqldb
pip3 install mysqlclient
python3 manage.py makemigrations
python3 manage.py migrate
Download and install Mysql-python from here for windows environment. http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python.
if the error looks like this
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module:
dlopen(/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/_mysql.so, 2): Library not loaded:
/usr/local/opt/mysql/lib/libmysqlclient.20.dylib
Referenced from: /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/_mysql.so
then try :
pip install python-mysqldb
This happened with me as well and I believe this has become a common error not only for Django developers but also for Flask as well, so the way I solved this issue was using brew.
brew install mysql
sudo pip install mysql-python
This way every single issue was solved and both frameworks work absolutely fine.
P.S.: For those who use macports (such as myself), this can be an issue as brew works in a different level, my advice is to use brew instead of macports
I hope I could be helpful.
If you are using pyhton version 3.4 or above. you have to install
sudo apt-get install python3-dev libmysqlclient-dev
in terminal. then install pip install mysqlclient
on your virtual env or where you installed pip.
I wasted a lot of time on this. Turns out that the default database library is not supported for Python 3. You have to use a different one.
If you get errors trying to install mysqlclient with pip, you may lack the mysql dev library. Install it by running:
apt-get install libmysqlclient-dev
and try again to install mysqlclient:
pip install mysqlclient
Faced similar issue. I tried installing mysql-python
using pip, but it failed due to gcc dependency errors.
The solution that worked for me
conda install mysql-python
Please note that I already had anaconda installed, which didn't had gcc dependency.
My answer is similar to @Ron-E, but I got a few more errors/corrections so I'm putting my steps below for Mac OSX on Mavericks and Python 2.7.6.
Install Python mysql package (if you get a success message, then ignore the below steps)
pip install mysql-python
When I did the above, I got the error "EnvironmentError: mysql_config not found" To fix this, I did the below in terminal:
export PATH=$PATH:/usr/local/mysql/bin
When I reran step 1, I get a new error "error: command 'cc' failed with exit status 1" To fix this, I did the below in terminal:
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
I reran step 1 and got the success message 'Successfully installed mysql-python'!
try:
pip install mysqlclient
I recommend to use it in a virtual environment.
On Ubuntu it is advised to use the distributions repository.
sudo apt-get install python-mysqldb
Install (if not found):
pip install mysql.connector
Settings:
'default': {
'ENGINE': 'mysql.connector.django',
'NAME': '...',
'HOST': '...',
'PORT': '3306',
'USER': '...',
'PASSWORD': '...',
}
you have to install python-mysqldb - Python interface to MySQL
Try
sudo apt-get install python-mysqldb
