Install Ruby

Quick reference

• 00:03 We got our text editor.
• 00:05 We've got our terminal, now all we need is the Ruby programming language itself.
• 00:09 So let's go head over to Google and type in ruby installer.
• 00:13 And the first thing that pops up should be this RubyInstaller.org for Windows,
• 00:16 go ahead and click this.
• 00:18 Now, if you are on a Mac or on Linux, you don't have to do anything.
• 00:21 Ruby comes installed on Mac or Linux.
• 00:23 It may be a different version, but that's perfectly fine.
• 00:26 So you don't have to do anything, you're ready to go.
• 00:28 Windows users, we need to come here and
• 00:30 install the Ruby programming language itself.
• 00:33 Now the nice thing about this website is this is an actual
• 00:36 little installer that's already been pre-compiled and everything.
• 00:40 So we just have to download one file, install it really quickly and
• 00:43 we're good to go.
• 00:44 So it's really, really nice.
• 00:46 And this is really the way everybody installs Ruby for Windows.
• 00:50 Now, you could go to the Ruby official website and download it itself and
• 00:53 sort of compile it yourself, but that's way beyond the scope of this course.
• 00:57 And there's no real reason to do that,
• 00:59 especially if you're just learning Ruby to begin with.
• 01:01 So here we're on the Downloads page.
• 01:03 And take a minute to read this, because these things change from time to time.
• 01:08 Different versions come out and sometimes there are different requirements.
• 01:12 So just read this little paragraph here.
• 01:14 It will tell you which one to install.
• 01:17 It just takes a second to read that.
• 01:18 So I recommend that you do that.
• 01:19 Now, you'll notice right here,
• 01:21 this is the one that they're recommending at the moment.
• 01:24 And it's sort of in bold, so we know that's the one.
• 01:26 So just go ahead and click this.
• 01:29 And we could save this anywhere, I'm just going to save it to my desktop.
• 01:34 A little bit bigger file, 121 MB,
• 01:36 should download fairly quickly with high speed Internet.
• 01:42 Okay, so once it's finished downloading, go ahead and click it to install.
• 01:46 We'll go ahead and accept the license, Next.
• 01:49 Now, we can install this anywhere we want, it doesn't really matter.
• 01:52 So we're just going to take the default here.
• 01:54 And make sure this add Ruby executable to your PATH box is checked.
• 01:59 That just means we can run Ruby from anywhere on our computer,
• 02:03 instead of just on the Ruby folder, right?
• 02:06 So we definitely want to be able to run Ruby all over our computer.
• 02:09 So make sure that this is checked.
• 02:11 The rest of these associate.rb files,
• 02:14 all your Ruby files will end in.rb, so that's normal.
• 02:18 See, it's not very big installation, 58 MB.
• 02:21 All right, so go ahead and click Install, and then click Next.
• 02:26 Okay, so I'm going to go ahead and pause the video while this does its thing, and
• 02:30 we'll resume as soon as it finishes.
• 02:32 Okay, so we finished the installation.
• 02:34 Now it's asking us if we want to run our ridk install to set up some other tools
• 02:38 that we may or may not need now.
• 02:40 We're not going to use these other tools in this course, but
• 02:43 we should probably install them anyway just because you would want to.
• 02:47 So make sure this is checked and click Finish.
• 02:50 And this box pops up, it asks which of these you want to install.
• 02:54 It's just going to go through and do each of them separately.
• 02:57 So let's click 1 and hit Enter.
• 03:02 All right, so that's been properly installed.
• 03:04 Now we want to hit 2 and hit Enter.
• 03:11 Okay, and then finally, let's do the third one, click 3.
• 03:19 Okay, and so we're done.
• 03:22 We can go ahead and close this.
• 03:24 And that's all there is to it.
• 03:26 Now, if you had already been running to git bash terminal, go ahead and
• 03:28 close it and restart it.
• 03:30 Once you install Ruby, you need to restart the git bash terminal.
• 03:33 And that's pretty much it.
• 03:34 So in the next video, we'll start writing Ruby code.
