Error Handling

Quick reference

• 00:04 We've installed Ruby and Rails, we created our new project, but
• 00:08 we got this error here at the end.
• 00:09 So what's going on?
• 00:10 Well, like I said in the last video, you're always going to get errors.
• 00:13 And the trick is to kind of look through here and try and
• 00:16 figure out what's going on, and then Google it.
• 00:20 So we could come up here.
• 00:22 Up until now, everything is going smoothly, we're fetching,
• 00:25 we're installing, fetching, installing, and then boom, we get this error.
• 00:29 So what you want to do is go to that part and then just kind of start reading.
• 00:32 And look through here and we're seeing sqlite3,
• 00:38 something, something, again,
• 00:41 a bunch of sqlite3 stuff, down here sqlite3.
• 00:46 sqlite3, so something tells me there's a problem with sqlite3, right?
• 00:52 So sqlite3 is actually the little database that comes with Rails.
• 00:56 I happen to know what's going on here, because this is a common thing, but
• 00:58 I'm not going to tell you right away.
• 01:00 I want to show you, if you didn't know, how would you fix it?
• 01:03 What you're going to want to do here is, like I said, start at the top and
• 01:06 just kind of start reading through here.
• 01:07 And try to find something that you can copy.
• 01:10 Right here, it says sqlite3.h is missing, install blah, blah, blah, first.
• 01:17 Well, okay, I'm just going to go ahead and select all this and
• 01:22 click copy, and then head over to Google, and just paste all that in.
• 01:27 And you're going to likely find something called stack overflow right here, and
• 01:32 stack overflow is a great website.
• 01:33 It's going to be your best friend, especially with Rails, and
• 01:36 what it is is basically just a social media website for coders.
• 01:39 And you can go and post questions and other people will help you out.
• 01:43 And all of the past questions and answers are all listed, so
• 01:47 you can search through them.
• 01:49 Likely, somebody else already had this problem, we can search and
• 01:52 find the answer, it's really really great.
• 01:54 So I'm just kind of look through here and what I want to look for
• 01:58 usually, first is stack overflow.
• 02:00 because you're almost always is going to find your answer there, and
• 02:02 then down here, look at the dates.
• 02:04 You kind of want the most current ones, so here's one from 2012, 2013,
• 02:08 that's probably not it.
• 02:09 Here's one from 2019, now we're talking.
• 02:12 Look at this, how do I install SQLite3 while setting up Ruby on Rails?
• 02:15 That's exactly what we're doing, so this is very promising.
• 02:18 And you can just kind of come through here and they all kind of look like this.
• 02:21 This is the layout of this website and he's asking this question.
• 02:25 And you just kind of scroll down until you get answers and just kind of read.
• 02:29 And here it says Rails tries to automatically install the latest version
• 02:33 of the SQLite gem.
• 02:34 But that new version doesn't work with Rails yet, so
• 02:37 that's the problem we're having.
• 02:39 And instead, it wants us to just designate
• 02:44 an older version of SQLite3 in our gemfile.
• 02:48 Now, we don't know what a gemfile is yet, but
• 02:51 I'm going to probably show you that in the next video.
• 02:54 And it's actually really simple, but for now, this is a very minor error and our
• 02:58 project will actually work without fixing this, we'll fix it in the next video.
• 03:02 But for now, head back over to our Git Bash.
• 03:05 And we can just type in the cd command to change directory and
• 03:08 we want to go to pinteresting.
• 03:13 That's the project we just created, oops,
• 03:17 cd pinteresting, there we go, slash at the end.
• 03:22 And you can see now, if we pwd,
• 03:24 we are in fact in this directory and we're ready to go.
• 03:28 So in the next video, we'll jump in,
• 03:30 I'll show you our new project that we've just created.
• 03:33 And we'll go ahead and fix that error for
• 03:38 the final time and move on from there.
