<p>I'm trying to install Facebook SDK for Python from here
<a href="https://facebook-sdk.readthedocs.io/en/latest/install.html#installing-from-git" rel="nofollow">https://facebook-sdk.readthedocs.io/en/latest/install.html#installing-from-git</a> 
Here's the full code</p>

<pre><code> virtualenv facebookenv
source facebookenv/bin/activate
pip install -e git+https://github.com/mobolic/facebook-sdk.git#egg=facebook-sdk
</code></pre>

<p>The <code>virtualenv facebookenv</code> and <code>pip install -e git+https://github.com/mobolic/facebook-sdk.git#egg=facebook-sdk</code> works well in the Windows Command Prompt but not <code>source facebookenv/bin/activate</code>. When I try to run it returns tha source is not recognized command.</p>
