问题
Okay I recently upgraded from Ubuntu 10.04 to 12.04
Only to be faced by a lot of problems. I am a newbie at this so you might have to tell me in a little more detail or step-by-step
I had a django project that was working perfectly but now it gives me this error :
File "/usr/local/lib/python2.7/site-packages/django/db/backends/mysql/base.py", line 16, in <module>
raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: libmysqlclient_r.so.16: cannot open shared object file: No such file or directory
or in python :
>>> import MySQLdb
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "build/bdist.linux-i686/egg/MySQLdb/__init__.py", line 19, in <module>
File "build/bdist.linux-i686/egg/_mysql.py", line 7, in <module>
File "build/bdist.linux-i686/egg/_mysql.py", line 6, in __bootstrap__
ImportError: libmysqlclient_r.so.16: cannot open shared object file: No such file or directory
Anyways I thought there was some problem with my MySQL-python so I tried re-installing it.
sudo pip install mysql-python
gives :

Again now I have gone to this link : http://pypi.python.org/pypi/setuptools/0.6c11 to download and install setuptools.. I have also installed the latest distribute 0.6.8 from here : http://pypi.python.org/pypi/distribute/0.6.8
I have also tried uninstalling the previous versions and installing back but it doesn't seems to work. I have got Python 2.7.3 installed
Could someone please explain to me what is going on... How I can install Mysqldb...
I have also ran these commands on shell :
sudo apt-get install mysql-server mysql-client python-mysqldb libmysqlclient-dev python-dev
But it didn't help ...
UPDATE I JUST DID THIS AND GOT THIS ERROR :
nabeel@nabeel-pc:~$ pip uninstall setuptools

UPDATE 2 : I have managed to install virtualenv now in the environment I have also managed to install MySQLdb. Here's theh error I get while running my server :
sudo python manage.py syncdb
I get this error:
File "/usr/local/lib/python2.7/site-packages/django/db/backends/mysql/base.py", line 16, in <module>
raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e)

回答1:
Using virtualenv
First things first. Make sure you have Mysql, Setuptools and some essentials:
sudo apt-get install mysql-server
sudo apt-get install python-setuptools python-dev build-essential
Now install VirtualEnv:
sudo easy_install -U virtualenv
Create a Virtual Environment. As the documentation says: virtualenv is a tool to create isolated Python environments. This means that the chances of getting a conflict are really small. Here "myenv" is the name of a folder where you can access your environment, so create it where you want.
virtualenv --distribute myenv
Then go to "myenv" directory and run this to activate it:
source myenv/bin/activate
You need to install libmysqlclient-dev to get MySQL-python working:
sudo apt-get install libmysqlclient-dev
Now you're ready to install MySQL-python:
pip install MySQL-python
and everything should be working.
When you don't want to work in that environment anymore, write in the terminal:
deactivate
UPDATE:
Since this answer keeps getting upvotes, let me show you how to do the same using conda, which has become my favorite environment nowadays. First you have to install anaconda (I believe you can also install miniconda, which is a lighter version that includes conda and some packages.) Here you will find the installer for Linux, OS X and Windows. It is a big file but contains a lot of pre-compiled packages ready to be installed. Assuming you already have installed anaconda, you can simply run:
conda create -n mysql-env python
mysql-env is the name of the environment (you can call it whatever you want) and python is the default version of python to be installed (currently, 2.7.10). Alternatively, install other version of python with conda create -n my-new-env python=3.4.
Then you activate your environment:
source activate mysql-env
and finally install mysql-python:
conda install MySQL-python
(I think conda install mysql-python also works)
And that's all.
回答2:
easy_install -U distribute solved my problem
回答3:
In some Ubuntu installations, you'll also want to consider libmysqlclient-dev:
sudo apt-get install python-dev libmysqlclient-dev
It also held me back. The other responders probably already had it installed and didn't realize it was required.
