1 00:00:00,600 --> 00:00:08,520 In a previous lecture in this course, you learned how to upgrade your node raid server version to the 2 00:00:08,520 --> 00:00:10,470 latest available version. 3 00:00:10,950 --> 00:00:18,390 In this lecture, I'll show you how to do the same for the underlying Node.js server on which no threat 4 00:00:18,660 --> 00:00:19,290 is based. 5 00:00:19,800 --> 00:00:27,180 You can see here that I've looked into my note read save on my Raspberry Pi inside the node red directory 6 00:00:27,180 --> 00:00:35,130 where node radius installed and have used the command node minus V to get the current version of Node.js 7 00:00:35,400 --> 00:00:38,340 on which my node installation is running. 8 00:00:38,760 --> 00:00:43,260 And as you can see, it's version 16.1 5.0. 9 00:00:43,980 --> 00:00:51,900 If I go on to the Node.js website and have a look at the latest available version, I can see that the 10 00:00:51,900 --> 00:00:57,510 stable version or the long time service revision is 16.15 point one. 11 00:00:57,900 --> 00:01:00,810 So there is a minor update to the package. 12 00:01:01,260 --> 00:01:06,990 There's also the the current latest version, which is at 18 .3.0. 13 00:01:07,380 --> 00:01:14,190 I tend to prefer to go with the ltz versions rather than the latest available version for stability 14 00:01:14,190 --> 00:01:14,670 reasons. 15 00:01:14,670 --> 00:01:21,420 And typically I don't need to have access to the bleeding edge features of Node s. 16 00:01:22,570 --> 00:01:26,900 Another thing that I want to mention here in relation to the relation between the versions of note rate 17 00:01:26,950 --> 00:01:33,250 and note, J.S. is here in the release plan on the note rate website. 18 00:01:33,760 --> 00:01:33,980 All right. 19 00:01:34,000 --> 00:01:39,940 Just go to the great dot org about releases this link right here and you can see what the plan is going 20 00:01:39,940 --> 00:01:45,630 ahead and recording this around here in June 2022. 21 00:01:45,640 --> 00:01:51,520 And you can see that the current version of note rate, the latest version is 3.0, even though I'm 22 00:01:51,520 --> 00:01:54,760 running 2.2 in this example. 23 00:01:55,120 --> 00:02:03,370 But you can see that the supported versions of note on note 12 in maintenance mode, note 14 also in 24 00:02:03,370 --> 00:02:11,410 maintenance mode and to note 16 which is in active mode and note 16 will be in active mode up to later 25 00:02:11,500 --> 00:02:12,280 this year. 26 00:02:13,060 --> 00:02:18,670 Having a look at my running version of note read, just go in here. 27 00:02:19,030 --> 00:02:20,770 You can see did version 2.2. 28 00:02:21,070 --> 00:02:24,250 So I should probably upgrade to version three at some point soon. 29 00:02:25,180 --> 00:02:25,570 All right. 30 00:02:25,570 --> 00:02:35,530 So there's a few different ways by which I can go ahead and do the upgrade of the Note J.S. installation 31 00:02:35,530 --> 00:02:36,700 on my Raspberry Pi. 32 00:02:37,210 --> 00:02:45,130 But the method that I prefer is via is by using the NPM package manager, and there's a particular package 33 00:02:45,130 --> 00:02:52,420 in here called in which allows me to interactively manage my Node.js version, try out a few other methods 34 00:02:52,420 --> 00:02:52,750 as well. 35 00:02:52,750 --> 00:02:59,020 But I find that the NPN and version, the interactive manager for Node.js, is the easiest and most 36 00:02:59,020 --> 00:03:00,040 reliable method. 37 00:03:00,460 --> 00:03:04,120 So that's what I'm going to use in this example, in this lecture. 38 00:03:04,960 --> 00:03:15,010 So I've already ran the node of the command to get the current version of Node J.S. and it's 16.1 5.0. 39 00:03:15,970 --> 00:03:26,650 The next thing that I'll do is I'll clear the NPM cache and do that using NPM cache clean and F is for 40 00:03:26,680 --> 00:03:27,250 force. 41 00:03:28,030 --> 00:03:29,800 That's going to clear the cache. 42 00:03:31,790 --> 00:03:37,160 And just note that I'm doing all this work inside the don't know to read directory. 43 00:03:37,820 --> 00:03:38,150 All right. 44 00:03:38,160 --> 00:03:38,840 And that's done. 45 00:03:39,230 --> 00:03:44,210 Now, I've already done this earlier, but in case you haven't done it, you need to go ahead and install 46 00:03:44,210 --> 00:03:51,710 the end package or the the note version manager, then do that using NPM install. 47 00:03:56,450 --> 00:04:00,170 G and you find a command for that and. 48 00:04:02,690 --> 00:04:03,370 They're right here. 49 00:04:05,540 --> 00:04:06,800 And that's going to instill in. 50 00:04:12,760 --> 00:04:13,140 Okay. 51 00:04:13,150 --> 00:04:19,450 And the reason that I got the error messages is that I actually need to use pseudo in order to run this 52 00:04:19,450 --> 00:04:20,830 command as a super user. 53 00:04:21,460 --> 00:04:24,280 So I'm going to clear this and try again with pseudo. 54 00:04:25,780 --> 00:04:27,040 And p m. 55 00:04:30,150 --> 00:04:30,930 Install. 56 00:04:32,880 --> 00:04:34,260 G and. 57 00:04:46,140 --> 00:04:46,590 Okay. 58 00:04:47,520 --> 00:04:48,090 Well done. 59 00:04:49,870 --> 00:04:57,940 And you can see I already had version 8.25.5 installed and what I've just done upgraded my end package 60 00:04:58,510 --> 00:05:00,970 to eight point 12.1. 61 00:05:01,510 --> 00:05:05,830 Now that I've got an installed, I can go ahead and upgrade. 62 00:05:06,790 --> 00:05:09,360 Note to the latest version. 63 00:05:09,440 --> 00:05:14,290 So I said I'm going to go for the latest stable version, which this version right here. 64 00:05:14,860 --> 00:05:24,550 So the command for that is sudo and use the end package manager to install the stable version of new 65 00:05:24,550 --> 00:05:25,270 to chase. 66 00:05:27,840 --> 00:05:28,950 And run his command. 67 00:05:30,080 --> 00:05:33,830 You can see that he picked Vision 16.2, 15.1. 68 00:05:33,890 --> 00:05:38,480 The latest available LTE version and it's continuing with the installation. 69 00:05:40,490 --> 00:05:40,790 Okay. 70 00:05:40,790 --> 00:05:44,430 So it's completed with the installation notes. 71 00:05:44,450 --> 00:05:46,160 Have a look at the current version. 72 00:05:46,160 --> 00:05:51,980 Again, I'm going to use the command node V just like before. 73 00:05:52,610 --> 00:05:56,570 And you can see they're just showing me 16.15 point one. 74 00:05:56,900 --> 00:06:05,870 If in your case is showing the old version of a node J.S., then use the hash command goes like this 75 00:06:06,080 --> 00:06:10,330 hash to basically rehash Node.js. 76 00:06:10,330 --> 00:06:16,280 J.S. And then run note the again and it will show you the correct current version of note. 77 00:06:17,130 --> 00:06:23,960 Now, another thing that I should show you before we go on and restart Node, read this in case you 78 00:06:23,960 --> 00:06:30,950 want to go for a newer version of for the latest version of Node.js. 79 00:06:31,220 --> 00:06:40,360 What you can do is to use the end command again and install the latest version of Node.js. 80 00:06:40,370 --> 00:06:44,870 In this case, it would go for version 18 .3.0. 81 00:06:44,900 --> 00:06:51,680 Not going to do that, of course, now, or if you want to be specific about which version of Node she'd 82 00:06:51,680 --> 00:06:57,920 like to install, then instead of stable or latest, you can just be specific and say I'd like to install 83 00:06:57,920 --> 00:07:07,400 version say 18 .3.3 and then the end vision manager will install the specific version of note that you 84 00:07:07,400 --> 00:07:08,120 have requested. 85 00:07:09,470 --> 00:07:09,770 All right. 86 00:07:09,770 --> 00:07:14,630 So the upgrade of Node.js is now finished. 87 00:07:15,140 --> 00:07:19,010 For this change to take effect in node red, you need to restart it. 88 00:07:19,010 --> 00:07:28,670 So the way you do this is first I stop node red to say Node stop and then start it. 89 00:07:31,930 --> 00:07:32,970 Know, Rich start. 90 00:07:35,810 --> 00:07:36,920 Give it a moment to spin up. 91 00:07:44,350 --> 00:07:53,110 And you see here that the note James version, that note read is using is six point 15.1, which I just 92 00:07:53,860 --> 00:07:54,550 installed. 93 00:07:55,490 --> 00:07:56,780 And just kind of refresh. 94 00:07:57,940 --> 00:07:58,170 Okay. 95 00:07:58,190 --> 00:07:58,980 It's not ready yet. 96 00:08:03,780 --> 00:08:05,970 I'm waiting for the dashboard to start as well. 97 00:08:06,000 --> 00:08:07,290 After the polite notes. 98 00:08:11,110 --> 00:08:11,680 All right. 99 00:08:12,590 --> 00:08:13,110 Here you go. 100 00:08:13,190 --> 00:08:14,390 And that should work now. 101 00:08:18,550 --> 00:08:20,040 And don't release back up. 102 00:08:23,750 --> 00:08:30,650 And that's how you can upgrade the version of Node.js used by trade.
