Rails Installation

Quick reference

• 00:05 We've downloaded and
• 00:06 installed all the tools that we need in order to install Rails.
• 00:09 Now the only thing left to do is install Rails, so head back over to Google and
• 00:13 type in Rails installer.
• 00:16 And the first thing that pops up is this Railsinstaller.org.
• 00:20 Go ahead and click that.
• 00:21 And this is not the official Ruby on Rails Web site.
• 00:23 You can go to the official Ruby on Rails website and download Ruby on Rails there,
• 00:27 but I don't recommend that you do it.
• 00:29 It's very hard to install actual Ruby on Rails on a computer,
• 00:33 you have to download and install all kinds of other things.
• 00:36 And we've already installed quite a few things.
• 00:39 You don't want to be installing even more stuff on top of that.
• 00:41 And it's just really complicated.
• 00:43 This RailsInstaller has been around forever, and
• 00:47 it's a little package you can download, just one click install.
• 00:51 And it will do all the things that you need for you.
• 00:54 So if we scroll down here there's Windows and a Mac version, whichever you're on.
• 00:58 Now I'm on a Windows so we want this one.
• 01:01 And there's two different versions, this one has Ruby 2.2, and
• 01:06 this one has Ruby 2.3.
• 01:07 Inside of here you could see there's some subtle differences,
• 01:11 it will install Rails 5.0, this one will install Rails 5.1.
• 01:16 I think the current version of Ruby on Rails is 5.2 something.
• 01:19 So it really doesn't matter which version you have as long as it's 5 something,
• 01:24 it really doesn't matter.
• 01:25 It will also install Bundler and Git.
• 01:28 We've already installed Git Bash.
• 01:29 It has a version of Git installed with it so we don't really care about that.
• 01:33 SQLite is a database that comes with Rails.
• 01:36 And then DevKit down here is something that comes with Ruby, so
• 01:39 there's all kinds of stuff that need to be installed.
• 01:42 Like I said, this RailsInstaller will do all that stuff for you, and
• 01:45 that's really cool.
• 01:46 I'm going to go ahead and click this one, just the latest version, and
• 01:50 we can download this anywhere.
• 01:51 I'm just going to download it to our desktop again.
• 01:54 Now this is quite a bit bigger of a file.
• 01:58 It's 112 megabytes so if it takes a couple of minutes to download, no big deal.
• 02:03 Now this is a package, and once it installs it will actually install, I don't
• 02:07 know, 5 or 600 megabytes worth of stuff on your computer, so that's kind of cool.
• 02:12 I'm going to go ahead and pause this video as it downloads and
• 02:14 we'll pick it up as soon as it finishes.
• 02:16 Okay, so I've finished downloading.
• 02:18 Now we just go ahead and click it to install.
• 02:22 And click Run, and we get the basic license, go ahead and accept that.
• 02:27 And this can install anywhere but
• 02:29 the default is the C:\RailsInstaller directory so just go ahead and leave that.
• 02:33 Now, I would recommend that you uninstall or uncheck this Install Git,
• 02:37 because like I said we've already got Git on our computer because we downloaded
• 02:40 the Get bash terminal.
• 02:42 It comes with Git so we don't have to install that again.
• 02:45 We want to definitely make sure that this box is checked.
• 02:48 Remember we talked about path earlier?
• 02:49 This will allow the Ruby programming language to run from anywhere on your
• 02:54 computer, not just the Ruby Directory, right?
• 02:57 So again, like I said, 522 megabytes lot of stuff here, something like,
• 03:02 I don't know, 20,000 files or something, it's huge.
• 03:05 So go ahead and click Install, and this is going to do its thing,
• 03:08 I'm going to go ahead and pause the video again it works and
• 03:11 we'll pick it back up as soon as it finishes.
• 03:14 Okay, so we get this Finish installation screen,
• 03:17 which means everything looks to have installed correctly.
• 03:21 So we can go ahead and click Finish, and that's pretty much it.
• 03:24 Now we still need to make sure that there were no errors and
• 03:27 to create our first project to see that everything installed correctly.
• 03:32 And we go ahead and do that in the next video.
