i have seen so many questions, and installed so many things as:
python3.7-dev
python3-dev
python-dev
pip install mysqlclient==1.4.2.post1
pip install mysqlclient
sudo apt-get install python3.7-dev default-libmysqlclient-dev
apt-get install python3.7-dev libmysqlclient-dev
sudo apt-get install libssl-dev
pip install mysql-connector-python
nothing seem to work for me, and i don't know what to do anymore, any help is appreciated.

Problem Solved thanks to Nigel Savage, as he suggested i'll list what i did:
Ubuntu version 18.04.03 LTS
VPS: Google cloud instance
python 3.7.5 using virtualenv
apt-get install python3.7-dev
apt-get install python3.7-dev libmysqlclient-dev
apt install build-essential
pip install mysqlclient==1.4.2.post1

Can't Install psutil

Can someone help me understand why I can't install psutil? I'm on MacOS. I'm a noob so bear with me, but any help would be appreciated. Could it be something to do with the default Python install vs v3 that I installed? I'm new to command line so confused about what is causing the error and how to fix it...
This is the error message I get...
kasey#MacBook-Pro ~ % pip3 install psutil

This happens when you have multiple versions installed (as for me, I had python 3.5 along with 3.7 installed), you have to specify a granular version, like so (for 3.7):
sudo apt-get install python3.7-dev -y
Read more:
https://github.com/giampaolo/psutil/issues/1143#issuecomment-334695523

For the same issue on AWS for python3, you will likely need to specify the version more explicitly:
yum install python36-devel.x86_64
Or just search for the right package name:
yum search python | grep -i dev

Is there a way to connect mariadb with python2.7

In my mac OSX i'm trying to use python2.7 and mariadb.
I am using pip install mysql-python or pip install mysqlclient as a connector. But system always give me bunch of error. Any other way to overcome this issues?

Traceback (most recent call last):

This is a good example why people shouldn't access internal/undocumented members of a structure instead of using a API function.
MariaDB's client library doesn't have a reconnect option in the MYSQL structure, according to the documentation for MySQL and MariaDB the reconnect option should be set via mysql_options(mysql, MYSQL_OPT_RECONNECT, &reconnect);
However, this issue is already fixed in MySQLDB so you should download latest source and build the module locally (assuming that Python 2.7 modules won't be updated any more)

Fatal error: 'my_config.h' file not found on Mac Mojave during install of Python MySQL

I have a project which has a dependency on MySQL-python==1.2.5
I have checked out answers like this, this and this. However none of the steps mentioned in all those answers helped.
So this project is a Django application with a dependency on MySQL-python as mentioned above. The project is in Python 2.7 and cannot be upgraded to Python 3.X.
When I run,
pip install MySQL-python
I get the below as the error:

I have tried using a different virtual env, tried updating homebrew before doing the above steps. I still cant get this to install.
Is there any way to get this working?

This procedure worked for me:
brew remove mysql
brew install mysql#5.7
brew link --force mysql#5.7
pip install mysql-python
I read a post and adjusted the procedure to link things in the /usr/local/bin instead of adding a new route to the PATH variable.
Reference: MacOS: "pip install MySQL-python" returning an error: "_mysql.c:44:10: fatal error: 'my_config.h' file not found"

You probably do not have the python development headers installed. On debian flavors:
sudo apt-get install python-dev
On other unix flavors, sometimes it's called python-devel
