Install Django & Pip Freeze Inside and Outside The Virtual Environment

Quick reference

• 00:04 In this video we′re going to download and install Django.
• 00:07 So, installing Django is really, really easy,
• 00:10 we′re going to actually do it straight from our terminal.
• 00:14 You notice I'm in my c/mywebsite directory and
• 00:17 you notice that our virtual environment is turned on.
• 00:20 It′s very important that you′re in your virtual environment.
• 00:24 So before we install Django, I want to show you something really quickly.
• 00:27 You can see what sorts of things have already been installed
• 00:31 in your virtual environment by typing the command pip freeze.
• 00:35 And if we do this, nothing happens.
• 00:37 It just doesn't do anything.
• 00:40 Well, that's because we haven't actually installed anything inside of our virtual
• 00:43 environment yet, so there's nothing to see.
• 00:45 But after we install Django, we'll go ahead and do the pip freeze thing again.
• 00:49 And you'll see that in fact, Django has been installed, and that's kind of cool.
• 00:52 Along the way from time to time, depending on what you're doing with Django,
• 00:56 you'll have to install other modules and other Python things.
• 01:00 And you can always use that pip freeze command to see what's been installed in
• 01:04 your virtual environment up until now.
• 01:06 So, all right, now let's go ahead and install Django.
• 01:09 And to do that, we're going to use pip again and
• 01:12 pip is the Python installation program pip, Python installation program.
• 01:16 What PIP does, is it installs things on your computer?
• 01:20 It goes out onto the internet, grabs them, downloads them and
• 01:23 installs them all for you.
• 01:25 And it's just really easy and really great to use.
• 01:28 It's just a nice Python thing.
• 01:29 So we're going to go ahead and take advantage of that and
• 01:32 use it to install Django.
• 01:33 Now you can go to the Django website and
• 01:36 download it like you would any other program.
• 01:38 Like we installed the Sublime Text Editor and we installed Python itself and
• 01:42 we installed the Git Bash terminal.
• 01:43 But this is the better way to do it.
• 01:45 You really want to do it from the command prompt.
• 01:47 You don't want to go to the Django website and download it from there.
• 01:50 So, all right, let's go ahead and pip install django.
• 01:55 Now before I do this, this will install the most current version.
• 01:59 If you have a different version that you want to download for a specific project,
• 02:04 if you've created a Django project a couple of years ago,
• 02:07 and it was using an older version of Django, and
• 02:09 you have to use that same older version to work on it.
• 02:12 To do that, you would just type in two equal to signs.
• 02:15 And then designate whatever version you want to download.
• 02:18 So if you wanted to download for instance 2.0.1, you would just do that.
• 02:25 So we don't want to do that.
• 02:26 We just want to download and install the latest version.
• 02:28 So we could just pip install django and hit Enter.
• 02:32 And you see it's collecting Django.
• 02:34 It's also collecting sql parse.
• 02:36 That's a database thing, and it's also collecting pitz.
• 02:40 That's a Python time zone file.
• 02:42 Django uses that for different things.
• 02:47 And you can see it's installing these packages sqlparse,
• 02:51 Python time zone, that's asgiref, and Django itself.
• 02:55 So we've successfully installed this django 3.0,
• 03:01 python tz 2019 and sqlparser 3.0 now it's installed Django 3.0.
• 03:09 This just came out.
• 03:11 If this number changes by the time you watch this video, no big deal,
• 03:14 just go ahead download the latest version.
• 03:15 And you should be good to go.
• 03:16 So, okay, it looks like it's been installed successfully.
• 03:20 Let's clear our screen.
• 03:21 But let's run that pip freeze command, just to make sure.
• 03:25 And when we do we see these are the things that we just now install the sqlparser,
• 03:31 pytz, django itself version 3.0.
• 03:34 And then this thing as well.
• 03:36 Pip freeze.
• 03:38 PIP is a great tool to use.
• 03:40 You can uninstall things if you want, you could go pip uninstall, and
• 03:43 then just django, right?
• 03:45 If you want it to uninstall Django, for some reason you can do that.
• 03:48 I don't recommend you do that now.
• 03:49 Cause we definitely want to use Django.
• 03:52 So Django has been installed.
• 03:54 We're ready to go in the next video, we'll go ahead and start our project.
