How to install SQLAlchemy on Ubuntu? - python

I want to install Python and SQLAlchemy on Ubuntu. This is my command:
sudo easy_install sqlalchemy
But it has failed, what should I do?


Aha,sir,I can help you.
First step,you should intall the MySql,like these:
sudo apt-get install mysql-server
sudo apt-get install mysql-client
sudo apt-get install libmysqlclient15-dev
Second step,install the python-mysqldb:
sudo apt-get install python-mysqldb
Third step,install the easy_install:
sudo wget http://peak.telecommunity.com/dist/ez_setup.py
sudo python ez_setup.py
Forth step,install the MySQL-Python:
sudo easy_install MySQL-Python
Finally,sqlalchemy:
sudo easy_install SQLAlchemy


I installed it using pip. After installing mysql-server, mysql-client and libmysqlclient15-dev and I ran following commands to install it.
pip install MySql-Python
pip install SQLAlchemy


sudo pip install flask-sqlalchemy
This installs the SQLAlchemy package for Flask.

You have to install "headers" for C extension. In this case you should install libpq-dev
sudo apt install libpq-dev

Ubuntu Command 'pip' not found, but there are 18 similar ones (pandas) reintalling works uslly

Not able to install setuptools on linux mint

I used this command in terminal
sudo apt-get install python-setuptools
it throws up an error instead of installing -
Package 'python-setuptools' has no installation candidate

THis is a python package so you could use pip to install it
pip3 install setuptools

Try this:
sudo apt-get install python-pip
When pip is installed type in:
pip install setuptools

Cannot import installed python package

I'm trying to install python-numpy package on my ubuntu 14.04 machine. I ran sudo apt-get install python-numpy command to install it and it says the package has been installed but when i try to access it, i'm unable to do so.

When you type:
sudo pip install package-name
It will default install python2 version of package-name some packages might be supported in both python3 and python3 some might work might not
I would suggest
sudo apt-get install python3-pip
sudo pip3 install MODULENAME
or can even try this
sudo apt-get install curl
curl https://bootstrap.pypa.io/get-pip.py | sudo python3
sudo pip3 install MODULENAME
Many python packages require also the dev package, so install it too:
sudo apt-get install python3-dev
Also check for the sys.path [ make sure module is in the python path ]

virtualenv(python3.4), pip install mysqlclient error

I created virtualenv for django 1.9 project. I am trying to pip install mysqlclient or mysql-python but both of them gives me errors.
pip install mysqlclient
pip install mysql-python
both give me the same error message:
Command "python setup.py egg_info" failed with error code 1 in
/private/var/folders/r4/bkv_4t9s4r140pjkgv6lsq8w0000gn/T/pip-build-cdxcssp9/mysqlclient
any suggestions!?

Try to run this before:
Ubuntu:
sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install pymysql
pip install mysqlclient
In OSX:
sudo xcodebuild -license accept
brew install mysql-connector-c

This is probably due to your mysql_config being broken.
As of 2019, here is how to run smoothly pip install mysqlclient on MacOS:
brew info openssl and follow the commands at the bottom
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.zshrc
export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"
Other approaches:
brew install/upgrade/reinstall mysql : did not fix the issue for me, but has the nice side effect to make sure your installation is clean.
brew install mysql-connector-c : to make that work you have to unlink mysql, which ruins your setup and it did not fix the issue for me.

If you're using Anaconda (which I highly suggest you) then run these two commands
conda install -c anaconda mysql-connector-python
and
conda install -c bioconda mysqlclient

Download the MySQL APT repository config tool (you can see more details here: http://dev.mysql.com/downloads/repo/apt/)
wget http://dev.mysql.com/get/mysql-apt-config_0.7.3-1_all.deb
Install the MySQL APT repository config tool
dpkg -i mysql-apt-config_0.7.3-1_all.deb
You will be asked to select product and version that you want to install. In the first step, select Server and next select either mysql-5.6 or mysql-5.7. Then click Apply.
Update APT
apt-get update
Install the server
sudo apt-get install mysql-community-server
sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install pymysql
pip install mysqlclient

If you are using Python 2.x, and already have installed:
MySQL Server
Python Connector
Then the problem is when you run:
Windows:
(your environment) SomePath> pip install mysqlclient
Mac OS:
$ pip install mysqlclient
Actually it is asking to install package for Python 3.x not 2.x. So it is throwing an error.
Solution is to run:
Windows:
(your environment) SomePath> pip install mysqlclient==1.3.9
Mac OS:
$ pip install mysqlclient==1.3.9
P.S The mysqlclient==1.3.9 version is the latest version for Python 2.x

For Ubuntu 18.04
sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install pymysql
pip install mysqlclient
and setup
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'DB_NAME',
'USER': 'DB_USER',
'PASSWORD': 'DB_PASSWORD',
'HOST': 'localhost', # Or an IP Address that your DB is hosted on
'PORT': '3306',
}
}

This worked for on Ubuntu 18.04
sudo apt-get install python3.6-dev
sudo apt-get install mysql-client
sudo apt-get install libsqlclient-dev
sudo apt-get install libssl-dev
