Line 1:
== Test if you have the required tools ==
In this step, we test if you have the ''virtualenv'' tool.
Take this moment to open up a command prompt. Enter the command:
<pre>
virtualenv --help
</pre>
You should see a help message that looks something like this:
<pre>
Usage: virtualenv [OPTIONS] DEST_DIR
Options:
--version show program's version number and exit
</pre>
If you don't see that friendly message, download ''virtualenv.py'' from here:
* [https://raw.github.com/pypa/virtualenv/master/virtualenv.py virtualenv.py]
and save it inside the ''django-for-designers'' folder.
Also, if you use Ubuntu or Debian, run the following command:
<pre>sudo apt-get install python-dev</pre>
It installs development-related tools that virtualenv relies on.
== Navigate to the django-for-designers folder ==
Open a command prompt, and use the ''cd'' command to find the ''django-for-designers'' 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 this command. The '''.''' at the end does matter, so be sure to type it!
<pre>
virtualenv .
</pre>
If you get a ''command not found'' error, type this instead:
<pre>
python virtualenv.py .
</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 bin/activate
</pre>
You should see your command prompt change to say ''django-for-designers''; 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!
