It installs development-related tools that virtualenv relies on.
== Navigate to the pages-to-apps folder ==
Open a command prompt, and use the ''cd'' command to find the ''pages-to-apps'' folder.
You can use the ''ls'' command to list the folder. Run this command:
<pre>ls</pre>
and make sure you see a requirements.txt file.
== Create a virtualenv ==
A virtualenv is a limited Python environment that permits you to install whatever Python code you like without impacting other Python programs.
First, we will have to create the virtualenv. In your command prompt, type:
<pre>
virtualenv env
</pre>
If you get a ''command not found'' error, type this instead:
<pre>
python virtualenv.py env
</pre>
Eventually you will get your prompt back.
== Activate the virtualenv ==
When you ''activate'' a virtualenv, it gives you access to the Python code within the virtualenv. (By contrast, your system Python does not have access to the code within the virtualenv.)
Run this command:
<pre>
source env/bin/activate
</pre>
You should see your command prompt change to say ''env''; that is how you know you have it activated.
== Install the requirements ==
You need to use the ''pip'' package manager within your virtualenv to install all the code required to have a successful tutorial. To do that, first make sure your command prompt has the virtualenv activated.
Then run:
<pre>
pip install -r requirements.txt
</pre>
This will run for a few minutes, downloading code. Eventually, you will get your prompt back. Success!
== Return to laptop setup ==
