title: Why is PyCharm unable to find the correct verion of pip to install a Python module?
body: <p>OSX: 10.9.5</p>
  
  <p>PyCharm: 4.5</p>
  
  <p>I am working on project in PyCharm IDE, using the 2.7.3 Python interpreter and need to import the<code>psycopg2</code> module. I tried to install the module with PyCharm, but it failed and asked me to do it manually:</p>

  <p>So I typed that command in the bash shell, the module installed and now it shows up in the project interpreter 2.7.2 but not in 2.7.3 !!!!!</p>
  
  <p>Maybe the <code>pip</code> version is too old? I upgraded pip from the bash shell: <code>pip install --upgrade pip</code></p>
  
  <ul>
  <li>python 2.7.2 shows version 7.1.0</li>
  <li><a href="http://i.imgur.com/8gIw9VZ.png" rel="noreferrer">python 2.7.3</a> shows version 1.5.6</li>
  </ul>
