title: Django: File "manage.py", line 10, in <module> execute_from_command_line(sys.argv)
body: <p>I am new to Python and Django. I am trying to install Django on Linux.
  Python version currently available on the server is Python 2.4.3 
  I installed Python 3.4.2 following the below steps:</p>
  
  <pre><code>wget https://www.python.org/ftp/python/3.4.2/Python-3.4.2.tgz
  tar -xvzf Python-3.4.2.tgz
  cd Python-3.4.2
  ./configure --prefix=/root/python3
  make
  make install
  </code></pre>
  
  <p>The python correctly got installed.
  so when I do <code>/root/python3/bin/python3.4</code> I get Python version 3.4.2
  so i created a soft link -> <code>ln -s /root/python3/bin/python3.4 python3</code></p>
  
  <p>Now i created a virtualenv through</p>
  
  <pre><code>/root/python3/bin/pyvenv-3.4 venv3.4
  source venv3.4/bin/activate
  </code></pre>
  
  <p>then i installed DJango:</p>
  
  <pre><code>pip install Django==1.9
  </code></pre>
  
  <p>Django got successfully installed</p>
  
  <p>Created the project myproj:</p>
  
  <pre><code>django-admin startproject myproj
  </code></pre>
  
  <p>myproj project successfully created:</p>
  
  <pre><code>cd myproj
  </code></pre>
  
  <p>now when i do <code>python manage.py migrate</code> i get error:</p>
