On Mac OS Sierra, created virtualenv using python2.7 and trying to install mysqlclient to use Django w/ MySQL. I installed MySQL 5.6 via homebrew. Running "pip install mysqlclient" gives these errors:
Running setup.py bdist_wheel for mysqlclient ... error

13 warnings generated.

Any help would be greatly appreciated.
The answer was installing dev tools using:
xcode-select --install
In my case I needed to do two steps:
xcode-select --install
as #howevilweare says AND also pip install with the brew installed openssl using an env command:
env LDFLAGS="-I/usr/local/opt/openssl/include -L/usr/local/opt/openssl/lib" pip install mysqlclient

When you install with pip you use the command pip and not python.
To see whether pip is correctly installed type:
pip help
See the following page for how to install and configure pip on Windows:
https://phoenixnap.com/kb/install-pip-windows
Your error output shows a problem with lxml. Looking into it I have found the page pip install lxml error which suggests the following solution:
sudo apt-get install --reinstall python-dev libpython2.7-dev.
I've tried common solutions written for mysqlclient error
1st try: brew install mysql-connector-c
2nd try:
LDFLAGS=-L/usr/local/opt/openssl/lib pip install mysqlclient
3rd try: brew install zstd
And mysql server is well-running.
But the error is not being fixed..
I am getting clang linker error saying library not found for -lzstd

In my case I did not had the sudo access so installed brew for my user
Check if your brew is not in default location
do this to check where you have installed brew
brew --prefix
output: Users/helloWorld/homebrew
use the output of above to set the ld flags and cpp flags
for example for me ssl and zstd libs were not found so this is what i did:
export LDFLAGS="-L/Users/helloWorld/homebrew/lib -L/Users/helloWorld/homebrew/opt/openssl/lib"
export CPPFLAGS="-I/Users/helloWorld/homebrew/include -I/Users/helloWorld/homebrew/opt/openssl/include"
and then do the pip install
pip3 install mysqlclient
I got following error when I am trying to install python-igraph using sudo pip install python-igraph

I also try to install C core using the link given in the answer UnicodeDecodeError when installing python-igraph
I would suggest you to use conda and the following command :
conda install -c conda-forge python-igraph

please help me solve this problem
Thanks guys!!
You need to install python-dev:
sudo apt-get install python-dev
And, since you are using python3:
sudo apt-get install python3-dev
This command should help you.
If you are using mac os you might try:
brew update && brew rm python3 && brew install python3
You need to brew has been installed already, otherwise you can install it. It is very useful for getting packages in Mac OS. http://brew.sh/
For Ubuntu you also need to install build-essential
sudo apt-get install build-essential
For those using different versions, such as Python 3.5, 3.6 or 3.7 I found this:
Part I
For Python 2.x use:
$ sudo apt-get install python-dev
For Python 2.7 use:
$ sudo apt-get install libffi-dev
For Python 3.x use:
$ sudo apt-get install python3-dev
For Python 3.4 use:
$ sudo apt-get install python3.4-dev
For Python 3.7 use:
$ sudo apt-get install python3.7-dev
Part II
If this still doesn't help, others have pointed out to install
$ sudo apt-get install build-essential
and finally
$ sudo apt-get install libssl-dev
But the last two didn't help me personally. Just in case, hope it helps you.
For those using python3.5:
apt-get install python3.5-dev
wget https://bootstrap.pypa.io/get-pip.py
python3.5 get-pip.py
pip3.5 install mysqlclient
Tried all of the above suggestions and a few found elsewhere and nothing worked. In the end the solution was simple enough (courtesy of ignacionf on GitHub):
pip install git+https://github.com/PyMySQL/mysqlclient-python.git
