I am trying to use mysql with django but run into a problem when using pip to install mysqlclient [duplicate]

I installed Python 2.7.15rci and Python 3.6.7 on Ubuntu. When i did 'pip list' on virtualenv it returns me:
Django (2.1.5)
pip (9.0.1)
pkg-resources (0.0.0)
pytz (2018.9)
setuptools (39.0.1)
wheel (0.32.3)
I'm trying to install mysqlclient (pip install mysqlclient) and returns an error.
unable to execute 'x86_64-linux-gnu-gcc': No such file or directory
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

So, I have tried different methods found like:
sudo apt-get install python-dev
sudo apt-get install python3-dev
sudo apt-get install libmysqlclient-dev
and some more... but none of them work for me and the problem persists.
Any suggestions?
Thank you!

gcc is part of the build-essential package, which you should install before anything else:
sudo apt-get install build-essential
UPDATE: Following #bosnjak's suggestion, you also might need to install the openssl developer tools:
sudo apt-get install libssl-dev

I specified the particular version of python it's 3.7
And that helped me
I have installed these ones:
sudo apt-get install python3.7-dev libmysqlclient-dev
And then installed mysqlclient by:
pip install mysqlclient

I turned out, that the solution is slightly different for almost every Python version. For those using different versions, such as Python 2.x, 3.5 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
For Python 3.8 use:
$ sudo apt-get install python3.8-dev
For Python 3.9 use:
$ sudo apt-get install python3.9-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 myself - but hoping this might help you!

You may do this before:
sudo apt-get install python3-dev default-libmysqlclient-dev build-essential
Source: https://pypi.org/project/mysqlclient/

This issue was persistent in Ubuntu and python 3+. In my case, I was using Ubuntu 18.04 and found this solution to be useful for python version 3.7.5
Step 1. Install libpython3.7-dev via sudo apt
> sudo apt-get install libpython3.7-dev
Step 2: Install mysqlclient
> python3 -m pip install mysqlclient==1.4.6

I wanted to install the 'Modoboa' mail-server package (https://github.com/modoboa/modoboa) on my Ubuntu 18.04 with Apache as my webserver, instead of nginx. I needed mysqlclient for Python 2.7. The following packages worked for me:
sudo apt-get install libssl-dev gcc python2.7-dev libmysqlclient-dev

I'm using the python3.8. Similarly to david's answer, use the following command then it works.
$ sudo apt-get install python3.8-dev

Why cant I install mysqlclient==1.3.10

I'm using a new MacOS High Sierra 10.13.5.
I first installed python3 using Homebrew:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install python
then I cloned my python project repository from github which has a requirements.txt file which has the line:
mysqlclient==1.3.10
I then created a virtual env and ran pip install:
python3 -m venv venv
pip install -r api/requirements.txt
and then I get the following error:

You are using pip version 10.0.1, however version 18.0 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
On my old mac book pro where I did not have this problem.
On that macbook I have python 3.6.5 using GCC 4.2.1.
On this new macbook I have python 3.7 using clang 9.1.0
(venv) $ python
Python 3.7.0 (default, Aug 22 2018, 15:22:33)
[Clang 9.1.0 (clang-902.0.39.2)] on darwin
This article is the only thing I can that seems related but doesnt seem to help much...
https://medium.com/#MrWeeble/homebrew-on-mac-and-pythons-mysqlclient-ea44fa300e70
any ideas for debugging would be appreciated. Thanks.

You need the MySQL client library and its related headers.
These are supplied in e.g. the MariaDB (MySQL fork) package in Brew, so brew install mariadb should do the trick.

First, are you sure you want to use MySQL-python? This is a mostly-dead project that's been semi-maintained for legacy support for the past half decade, and doesn't even work with current versions of MySQL. It wants 5.0 or maybe 5.1; the current version is 8.0, and even the current legacy version is 5.7.
Other options include:
mysql-connector, aka MySQLConnector/Python: This is the officially supported library, from MySQL/Oracle. It can be a bit slow, which doesn't matter for most projects, but it can sometimes. It also has a different API (although if you stick to DB-API 2 methods, the only difference is the connect call; beyond that it should just be low-level stuff that's different).
mysqlclient: This is the package that Django and some other frameworks use. It's an updated fork of MySQL-Python (with a few things from its abandoned successor, moist). It can even be configured to install itself as MySQLdb, the same name used by MySQL-python.
PyMySQL: A third-party package built to be as compatible as possible with the old MySQL-python but simpler and easier to maintain, and install.
cmysql, a fork of PyMySQL that's only slightly harder to install, but should be faster than it, or than mysql-connector.
Some linux distros—including, IIRC, recent versions of Ubuntu—provide a package named python-MySQLdb or similar that is not actually MySQL-python, but instead mysqlclient built with the install-as-MySQLdb option. So, if the only reason that you're trying to use MySQL-python is that it's what you were using on some Ubuntu box, it's probably not what you were using, and therefore not what you want.
Some of these alternative also require MySQL (specifically, MySQLConnector/C, aka libmysqlclient, and its development libraries), some don't—but they're all compatible with current versions. (Although there are some notes on 8.0 crypto changes in the docs for PyMySQL and cmysql, which you might want to read if you use 8.0.)
Anyway, if you really want MySQL-python, then you will need to install MySQL in a 5.x version. The INSTALL points you to MySQL downloads.
If you want 5.0 or 5.1, you will have to dig through the Downloads folder at one of the mirrors to find a source package and follow the instructions to build and install it, since there are no binary installers that work on current Macs.
If you want later 5.x versions—which, remember, are not supported by MySQL-python, but they might work—Oracle is still providing Mac binary installers for those. If you can't find them in the main downloads section, the mirrors' Downloads folder will have them. As of right now, 5.6 and 5.7 have binary installer packages that end with -macos10.13-x86_64.dmg.
However, you might be happier installing it with Homebrew. Follow the instructions on that page to install brew, then to use it to:
brew install mysql#5.5
MySQL-python also requires OpenSSL libraries, and Apple deliberately hides the ones used by the OS to prevent people from accidentally building code against an old version and not getting security updates. The newer libraries should all know how to handle this, but MySQL-python does not. The easiest way to install a usable OpenSSL is with Homebrew again:
brew install openssl
But don't just run that command and close the window. Read the output, because you have to do all the stuff it says if you want MySQL-python to build.

My issue was that I was using MySql Version 8.0.12. As soon as I downgraded to MySQL 5.7, it was installed perfectly. I used the following to delete the version 8 by following: https://gist.github.com/vitorbritto/0555879fe4414d18569d
The gist of the above was:
Check for MySQL processes with: ps -ax | grep mysql
Stop and kill any MySQL processes
brew remove mysql
brew cleanup
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/mysql
Restart your computer just to ensure any MySQL processes are killed
install mysql using brew: brew install mysql#5.7
Finally, pip install mysql-python

abamert's answer did not work for me. Though this did, you might try skipping the first step,
brew install mysql-connector-c
brew install mysql
brew link --overwrite mysql
pip install MySQL-python

Cannot install psycopg2 Ubuntu

Trying to get a server ready for a django project and I'm running into some issues with setup for postgres.
I'm following this guide:
https://jee-appy.blogspot.com/2017/01/deply-django-with-nginx.html
And I'm at step 5:
Now, we need to configure postgreSQL so that it can communicate with our Django application. For this, install psycopg2 database
adapter. But this adapter have some package dependencies, so first
install them.
run:
(django_env) $ sudo apt-get install libpq-dev python3-dev
then...
(django_env) $ pip install psycopg2
I do that, and this point in the instructions, I get a "compilation failed" error.
I tried the solutions suggested in this stack exchange question:
Trouble with psycopg2 in virtualenv python3 for use with Django
and this one:
Cannot install psycopg2 on virtualenv
I am very much a linux and django noob, so if this is a duplicate issue, please have mercy on me and leave a comment explaining why you are marking it as a duplicate as you do so.
Thanks for your time!

You've installed the python-dev libraries for Python 3. Your psycopg2 install is using python 2.7
If you want to use Python 3:
Make sure you've installed python3-pip
sudo apt-get install python3-pip
Then:
pip3 install psycopg2
If that still fails, try installing the development headers for postgresql:
sudo apt install python3-dev libpq-dev
pip3 install psycopg2
If on Python 2
sudo apt update
sudo apt-get install postgresql postgresql-contrib
sudo apt-get install libpq-dev
sudo apt-get install python-dev
sudo apt-get install python-pip
pip2 install psycopg2-binary
If on Ubuntu 20.04 or above
sudo apt-get install build-essential
Then run the other steps for either Python 2 or 3.

Note that on many distros, the development headers needed for compiling against libraries are not installed by default. For psycopg2 on Ubuntu you'll need the python3 and postgresql headers:
sudo apt install python3-dev libpq-dev
pip3 install psycopg2
These can be installed in your activated virtual environment.

I was testing my application on a ubuntu docker image that only has python2.7.6 installed (as happens in most big orgs)
If you are using python2.x (though you should plan to move to 3.x asap), check the below dependencies:
sudo apt update
sudo apt-get install postgresql postgresql-contrib
sudo apt-get install libpq-dev # this is required as psycopg2 uses pg_config
sudo apt-get install python-dev
sudo apt-get install python-pip
Now install psycopg2 using:
pip2 install psycopg2-binary

I had the same error trying to install it in a virtualenv (with python3)
I solved it by installing a previous version of psycopg2.
pip install psycopg2==2.7.5

This solved mine. I am using Python 3.8.2, Ubuntu 20.04 LTS:
sudo apt-get install python3-dev
sudo apt-get install python3-pip
pip install psycopg2

To install psycopg2 in ubuntu or mate 20 you need first to install:
sudo apt install libpq-dev
and then:
pip3 install psycopg2

In my case, I was facing this problem when I ran pip install -r requirements.txt to install all packages for a Django project on an Ubuntu machine, I ran into this error and many other installation errors.
To solve this one, I ran the following commands:
sudo apt install postgresql postgresql-contrib
sudo apt install libpq-dev
sudo apt install python3-dev
sudo apt install python3-pip
sudo apt install python3-psycopg2
pip3 install psycopg2
pip3 install psycopg2-binary
Plus, also check if the Ubuntu and Python and Psycopg versions are compatible together.
Also, #Arghya Bhattacharya answers pip install aiopg, solve the issue when i ran into it the second time.

I had to install this one as well on my Ubuntu 20.04 LTS:
sudo apt-get install build-essential

I faced same issue on my ubuntu 18.04 LTS OS.
Also, face some issues in Pillow. In both cases (psycopg2 and Pillow) these command solved my issue.
sudo apt install -y build-essential libssl-dev libffi-dev python3-dev libjpeg-dev libjpeg8-dev
sudo apt install libpq-dev
sudo apt-get install python3-pip
Note: I have installed psycopg2 in python=3.8.5 environment.

make sure you are using the correct psycopg version for the python version.
Example for python 3.8.
python 3.8, the supported version is psycopg 2.8.4.
Reference ubuntu 20.04 + python 3.8 , pip install psycopg2==2.7.3.2 error #1106

I solved this issue using another package which itself internally installs psycopg2.
pip install aiopg

I can't install Gevent

I need to install Gevent for python2.7 but after try almost all I still doesn't install it.
I have python 2.6.6 and here all work ok... but I need python2.7+ then I install python 2.7.9 and now have only problems...
Before some part of my project work in python 2.6 ok, but now my project doesn't run witn 2.6 and 2.7, dunno why it's stop working with 2.6 but nvm I need it with 2.7 but.... I cant instal gevent, I have installed libevent-devel an greenlet but I can't instal gevent

Installing this worked for me,
sudo apt-get install libevent-dev
sudo apt-get install python-all-dev
and then,
pip install greenlet
pip install gevent

There is solution for my problem enter link description here
Probably this is most important (in place of python2.X type your python ver. eg. python2.7)
export PYTHONPATH=$HOME/.local/lib/python/site-packages:$PYTHONPATH
export PYTHONPATH=$HOME/.local/lib/python2.X/site-packages:$PYTHONPATH
export PATH=$HOME/.local/bin:$PATH

It worked for me. First remove gevent from Pipfile.lock

Then install gevent manually pipenv install gevent
Hope it will work for you.

Had a similar issue, upgrading pip with
pip install --upgrade pip
worked for me. Make sure you have the latest version. In my case, I assumed making a new virtual environment automatically provides the latest version but I was wrong.

I managed to solve this same issue on my raspberry pi zero by using a compiled binary instead of pip.
sudo apt-get install python-gevent

Besides:
sudo apt-get install libevent-dev
sudo apt-get install python-all-dev
I also need to install (I used python3) to solve similar issue
sudo apt-get install python3-dev

I tried installing a bunch of other packages as described by some of the other answers, so not sure if any of those helped, but the thing that got it working in the end was using easy_install rather than pip:
easy_install gevent

I was getting errors trying to install gevent-websocket 0.10.1 however the problem was solved when I installed greenlet:
pip3 install greenlet
first and then:
pip3 install gevent-websocket
