I am trying to install mysqlclient in OSX 10.7 but I get this compiler error from gcc no matter what I try. I am using Python3.6 to run the setup.py script for mysqlclient.
You need to install XCode. The error message says that you don't have GCC in your mac. It will get installed as part of XCode

I followed the following steps to install Chrome in my Centos 7 system.
(base) [abc#bogon ~]wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
(base) [abc#bogon ~]sudo yum install ./google-chrome-stable_current_*.rpm
All was OK, but I got the following error while I run "google-chrome &".
(base) [abc#bogon ~]$ google-chrome &
[1] 4679
(base) [abc#bogon ~]$ /usr/bin/google-chrome: symbol lookup error: /usr/bin/google-chrome: undefined symbol: gbm_bo_get_modifier
I could not launch Chrome. How can I fix this error? Thanks.
This is due to a missing symbol in the libgbm library. You will likely need to update the mesa-libgbm package to a later version.
sudo apt update mesa-libgbm
sudo yum update mesa-libgbm
Or the equivalent for your OS.
When connecting my Django project to a database hosted on a remote VM, when I run python3 manage.py run server I get the error
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?
when I try python3 -m pip install mysqlclient to resolve the dependency, I get the error
ERROR: Could not find a version that satisfies the requirement mysqlclient (from versions: 1.3.0, 1.3.1, 1.3.2, 1.3.3, 1.3.4, 1.3.5, 1.3.6, 1.3.7, 1.3.8, 1.3.9, 1.3.10, 1.3.11rc1, 1.3.11, 1.3.12, 1.3.13, 1.3.14, 1.4.0rc1, 1.4.0rc2, 1.4.0rc3, 1.4.0, 1.4.1, 1.4.2, 1.4.2.post1, 1.4.3, 1.4.4, 1.4.5, 1.4.6, 2.0.0, 2.0.1, 2.0.2, 2.0.3)
ERROR: No matching distribution found for mysqlclient
I'd like to understand what is causing these issues and how to resolve it.
Thanks in advance!
I got it to work! For anyone facing the same issues run brew install mysql then try python3 manage.py runserver
For what it's worth, you might try installing the mysql-connector-c first. It seems heavy-handed to have to install MySQL to use a driver.
From:
How to install Python MySQLdb module using pip?
Mac OS
brew install mysql-connector-c
if that fails, try
brew install mysql
I have a brand new django 2.2.1 project I have just installed into a python 3.7 virtualenv on OS X (10.14.4). After some frustrations I got mysqlclient to install but when I run the django dev server it doesn't recognise that it is installed:
Here are the steps I've taken so far:
brew install mysql
pipenv --three
pipenv install django==2.2.1
pipenv install mysqlclient
brew uninstall mysql
brew install mysql-connector-c
pipenv install mysqlclient
brew unlink mysql-connector-c
brew install mysql
django-admin startproject projectname
Now, the only change I have made to the out-of-the-box django installation is to change the default database backend to django.db.backends.mysql and when I run the django server I get the following:
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?
However, going back to the virtualenv and doing "pip install mysqlclient" gives:
Requirement already satisfied: mysqlclient in /Users/<username>/.local/share/virtualenvs/<projectname>-KrUE_JNo/lib/python3.7/site-packages (1.4.2.post1)
Any ideas why django can't see the mysqlclient installed in the virtualenv? I can confirm that all of the above has been run in the virtualenv. I suspect it has something to do with the faff that OSX makes you go through to install it but I'm not sure how to pick it apart.
I have also tried to replace mysqldb with pymysql as suggested here but that causes the server to give a different error:
raise ImproperlyConfigured('mysqlclient 1.3.13 or newer is required; you have %s.' % Database.__version__)
django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.
Mysql is a given for this project so use of an alternative backend is not an option. Any help very gratefully received, many thanks in advance.

Following conor's post (thanks conor) I started again with a fresh virtualenv and again successfully installed mysqlclient1.4.2.post1. Here's the output from pip freeze now:
Django==2.2.1
mysqlclient==1.4.2.post1
pytz==2019.1
sqlparse==0.3.0
Still getting the same error when I do python manage.py runserver though:
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.
Did you install mysqlclient?
UPDATE 3:
Thought I would try importing the MySQLdb module on the python command line to see if I can get any more insight and it returns the following:
>>> import MySQLdb
Traceback (most recent call last):

SOLVED
So it looks like the issue was that on initial installation the mysqlclient library had compiled against the wrong version of mysql (not sure how that happened), so I had to force it to recompile.
Here are the steps:
brew uninstall mysql
brew uninstall myysql-connector-c
pipenv uninstall mysqlclient
brew install mysql-connector-c
At this point we need to update /usr/local/bin/mysql_config as per the instructions that conor linked to (thanks again conor), i.e. change the line that read
libs="$libs -l "
to
libs="$libs -lmysqlclient -lssl -lcrypto "
Then, to fix the resultant "library not found for -lssl" error I used the answer from this question:
export PATH="/usr/local/opt/openssl/bin:$PATH"
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
Then finally force mysqlclient to recompile and reinstall mysql:
pip install --force-reinstall --ignore-installed --no-binary :all: mysqlclient
brew unlink mysql-connector-c
brew install mysql
Thanks to everyone who took time to help out!
If you're on macos do this
$ brew uninstall mysql
$ brew install mysql-connector-c
$ brew unlink mysql-connector-c
$ brew install mysql
$ pip install mysql-python
and follow the instructions here: https://pypi.org/project/mysqlclient/
Downgrading from python 3.7.4 to python 3.6 solved the issue for me on windows 10.
I need to install mysqlclient module for python3.6 on my CentOS server via pip.
The instalation breaks with following error: OSError: mysql_config not found.
I've found a solution, to install mysql-devel package, but unfortunately it breaks with following error:
Error: mariadb101u-config conflicts with mysql-community-server-8.0.4-0.1.rc.el7.x86_64
Error: mariadb101u-libs conflicts with mysql-community-libs-8.0.4-0.1.rc.el7.x86_64
Error: mariadb101u-libs conflicts with mysql-community-libs-compat-8.0.4-0.1.rc.el7.x86_64
Error: mariadb101u-common conflicts with mysql-community-common-8.0.4-0.1.rc.el7.x86_64
I cannot remove the mysql-community packages, because the server is running MySQL database based on that.
Is there any way to fix it without removing conflicting packets?
Ok, found an answer:
yum install mariadb-devel gcc python36u-devel
Solution by #Djent worked for me.
But I kept on receiving time out error while installing through yum. If you are having the same problem. You can manually download the package and install it!
On CentOS
wget https://archive.mariadb.org/mariadb-10.1.39/yum/centos7-amd64/rpms/MariaDB-10.1.38-centos73-x86_64-devel.rpm
rpm -i MariaDB-10.1.38-centos73-x86_64-devel.rpm
For other linux OS, you can find mariadb-devel at https://pkgs.org/download/mariadb-devel
First run the command (take note of python version):
sudo yum install python36-devel
Then install mysqlclient using pip.
