Hi all I am tried to install the superset on OSX using the Python3. After the installation finished when I tried to add the Database using the mysql:// it said error No Module name MySQLDb. I tried to explore how to solved this, one of tutorial said try to install mysqlclient using pip3 install mysqlclient failed to install with error code mysql.h not found.
Than I following another tutorial used the mysql-connector. After I installed it, finally I can connect to mysql DB and insert table to the system. But when I tried to run the analysis from superset it said no data. Also I tried using SQL Lab and got the error args.
Updated: on my superset currently I am used the mysql+mysql-connector as URI Database connected properly, but when I tested to run a query it said execute() got an unexpected keyword argument 'args'. How to solve this?
Anyone have experience with this problem?
Thanks
Here is what works for me:
brew install python || true
brew install mysql || true
# Required for mysqlclient, see brew info openssl
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
# And now it works
pip3 install mysqlclient
Cheers!
Finally I got it working now.
What I am doing is reinstall the superset, run the brew install mysql-connector-c than run pip install mysqlclient

I am working on the setup of my first unmanaged vps(ubuntu 20.4) and following the document to connect my django site to mysql server "https://www.digitalocean.com/community/tutorials/how-to-create-a-django-app-and-connect-it-to-a-database"
able to setup
python/django/virtualenv
mysql server - tested from mysql workbench on my local machine-Ok
apache2 working ok. able to see the welcome screen with sqlite3.
now moving to mysql. i tried both the way('ENGINE': 'django.db.backends.mysql' and option file '/etc/mysql/my.cnf' to connect to mysql server from django project.
None of the alternatives working. activated virtualenv, installed mysqldb using
a) sudo apt install libmysqlclient-dev default-libmysqlclient-dev
b) pip install wheel
c) pip install mysqlclient
while trying to migrate following error encountered. tried with all the option available on stakoverflow, i found none of them working.
Error:

Did you install mysqlclient? "
with ubuntu 20.04 deafult python version is 3.8 and connecting to mysql with 3.8 is a bit challenge so you need to downgrade python to 3.6 or downgrade to ubuntu 18 if you are starting a fresh.
Found a tutorial to downgrade using alternatives and it worked. But had my other dependencies where i need python >= 3.7. So i had no other choice but refresh my ubuntu 20.04 on vps and configured with postgres. it is working way better than i expected with apache2/restframework/redis.
i suppose that i have a solution to this problem, so when we use a Ubuntu OS, i think that we need to run the next commands to work that package:
sudo apt-get install default-libmysqlclient-dev -y
sudo apt-get install gcc -y
pip3 install mysqlclient
Even if you already tried the first one, it might work. I have a Dockerfile in my GitHub of a Django app, if you want to test it later to see if it works on your machine, it took me a week to find the problem and deploy this app to Oracle Cloud because of this error.
Dockerfile
Am Trying to connect to my mysql db from django app.
I get the below error during migration:
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb
module. Did you install mysqlclient?
I've already installed mysqlclient as below:
Requirement already satisfied: mysqlclient in
/usr/local/lib/python3.7/site-packages (1.4.2.post1)
I've also tried with pymysql and adding below code to ini.py file:
import pymysql
pymysql.install_as_MySQLdb()
Gives me some other errors.
What could be wrong?
Python 3.7 , mysql 5.7 and Django 2.2 are my setup versions.
I had the same issue. Running the below command fixed it for me.
pip install --force-reinstall --ignore-installed --no-binary :all: mysqlclient
I had the same issue. The thing that worked for me is the following:
https://stackoverflow.com/a/54521244/12497648,
except when I did brew install mysql-client
I got the message Warning: mysql-client 5.7.23_1 is already installed and up-to-date
To reinstall 5.7.23_1, run "brew reinstall mysql-client" so I ran brew reinstall mysql-client after which I continued with the instructions from the link above (export PATH... etc.)
(also don't forget to do the pip wheel mysqlclient / pip install mysqlclient)
If the error includes a Reason: image not found error, then it can be solved with symlinks like this:
Library not loaded: #rpath/libmysqlclient.21.dylib Reason: image not found Django migrate error using mysqlclient DB driver and MySQL 8 with macOS
I have had no success at installing the MySQL Python connector on ubuntu 14.04. it appears that the production environment has version 1.1.6 installed. I have tried removing it with both pip and apt-get. I have attempted to update it also and have had no luck.
The command below does not work, I have tried with both "mysql-connector" and "mysql-connector-python"
pip install --user --allow-external mysql-connector-python mysql-connector-python
`
Downloading/unpacking mysql-connector-python Could not find any
downloads that satisfy the requirement mysql-connector-python Cleaning
up... No distributions at all found for mysql-connector-python
Storing debug log for failure in /root/.pip/pip.log`
If I run the command above, with just mysql-connector, it fails with an error about external managment.
"error: option --single-version-externally-managed not recognized"
I have also tried to manually remove it from "/usr/lib/python2.7/dist-packages/mysql_connector_python-1.1.6.egg-info" and that seems to have made no difference.
I have also downloaded the .deb from MySQL:
"mysql-connector-python-cext_2.1.3-1ubuntu14.04_amd64.deb" and used dpkg to install it, but that fails, as well as update fails.
Any advice?
I am new to Django and I try to follow the official tutorial. since I want to connect to mysql (installed on my computer, and i checked mysql module does exit in python command line), I set the ENGINE in setting.py to be django.db.backends.mysql . and then I tried to run
python manage.py syncdb
then I got error message like this:
Error loading MySQLdb module
and I cannot run
pip install mysql-python
the error msg is:
Unable to find vcvarsall.bat
so what is this error? and honestly I am not sure about the difference between mysql-python and mysql-connector-python. Since i tried with "pip install mysql-connector-python" and it tells me that requirement already satisfied...
You need to download the windows binary installer for the MySQL drivers for Python. Installing from source will not work since you do not have the development headers in Windows.
You need to install the mysql python connector
sudo apt-get install python-mysqldb
I installed homebrew and Xcode 4.3.2 with command line tools on Mac Osx Lion and when I now try to install mysql with :
brew install mysql -v
I get the error :
Error: #<BuildError: Failed executing: cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/Cellar/mysql/5.5.20 -DMYSQL_DATADIR=/usr/local/var/mysql -DINSTALL_MANDIR=/usr/local/Cellar/mysql/5.5.20/share/man -DINSTALL_DOCDIR=/usr/local/Cellar/mysql/5.5.20/share/doc/mysql -DINSTALL_INFODIR=/usr/local/Cellar/mysql/5.5.20/share/info -DINSTALL_MYSQLSHAREDIR=share/mysql -DWITH_SSL=yes -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DSYSCONFDIR=/usr/local/etc -DWITH_UNIT_TESTS=OFF -DWITH_READLINE=yes>
Here you find the full log :
https://gist.github.com/2421381
I checked the logs but there is nothing that can help me for the moment. Brew doctor is also clean and give no errors.
Found the solution with thanks to a reply of visoft on my gist post. This solution worked for me. The problem is coming from Cmake, I need version 2.8.7 instead of 2.8.8, run this code to get it work :
cd /usr/local
brew uninstall cmake
git checkout 948c2769 Library/Formula/cmake.rb
brew install mysql
After this, mysql was installed successfully.
