I am getting a strange error when trying to install mysqlclient on Ubuntu 16.04 Xenial with pip + Python 3.6:

 pip install mysqlclient

Output:

 _mysql.c:40:20: fatal error: Python.h: No such file or directory
 compilation terminated.
 error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

Following the installation requirements, I have tried installing the required libraries, but not luck so far.

sudo apt-get install python3-dev libmysqlclient-dev

Does someone know the workaround for this issue?

I found the problem, seems like for installing mysqlclient in python3.6 the library python3.6-dev is required.

Just open a terminal and run the following command:

sudo apt-get install python3.6-dev libmysqlclient-dev

You may get the following error when trying to install the library:

Reading state information...
E: Unable to locate package python3.6-dev
E: Couldn't find any package by glob 'python3.6-dev'
E: Couldn't find any package by regex 'python3.6-dev'

If that is the case, just try adding the following repository first:

sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update

After doing so, you should be able to install both python3.6 and python3.6-dev packages.

I had trouble installing mysqlclient on python 3.6.3, so I downgraded to version 3.6.2 and it worked.

sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev  libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
cd /usr/bin
sudo wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz
sudo tar xzf Python-3.6.2.tgz
cd Python-3.6.2
sudo ./configure --enable-optimizations
sudo make altinstall

python3.6 should point at 3.6.2

python --version # Python 3.6.2

now install mysqlclient

python3.6 -m pip install mysqlclient

    I didn't have to downgrade my versions but some package listed in `sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev` was apparently missing and that did it. So thank you! – Mathias Nov 21 '19 at 02:03

Open new terminal and run this command 

sudo apt-get install libssl-dev

after that install mysqlclient

pip install mysqlclient

Install MySQL database connector

First thing we will need to do is install python3-dev. You can install python3-dev by running the following command:

sudo apt-get install python3-dev

Once python3-dev is installed, we can install the necessary Python and MySQL development headers and libraries:

sudo apt-get install python3-dev libmysqlclient-dev

Then, we will use pip3 to install the mysqlclient library from PyPi. Since our version of pip points to pip3, we can just use pip.

pip install mysqlclient

Even though I'm late, I'd like to address a few things while answering your question.

Some suggests to install python3-dev, some suggests libmysqlclient-dev etc. But they might already have installed some of the packages thats required while installing and only installing the mentioned package made it work for them. However, it might not be the case with everyone.

You can refer to the mysqlclient's official documentation and scroll down to installation instructions for Linux - mysqlclient

Generally, these are the packages required before you can mysqlclient

sudo apt-get install python3-dev default-libmysqlclient-dev build-essential

Now, since you mentioned you ran this.

sudo apt-get install python3-dev libmysqlclient-dev

Looking at the documentation, you are missing these packages.

  • default-libmysqlclient-dev
  • build-essential

So, the answer for your question is

sudo apt-get install default-libmysqlclient-dev build-essential

And then you shoud install mysqlclient

pip install mysqlclient

Hope that answers.
