1 00:00:00,380 --> 00:00:03,280 It's a good idea to test the database you'll use in production in your 2 00:00:03,280 --> 00:00:05,540 development environment first. 3 00:00:05,540 --> 00:00:08,600 So we're going to need to install postgresql to our development machine. 4 00:00:09,810 --> 00:00:12,720 I'm using Mac OS with homebrew here, but you can see the teacher's 5 00:00:12,720 --> 00:00:16,380 notes if you want info on installing it to other operating systems. 6 00:00:16,380 --> 00:00:21,372 If you have Mac OS 10 and homebrew, it's as simple as typing 7 00:00:21,372 --> 00:00:26,470 brew install and the package you wanna install, postgresql. 8 00:00:32,381 --> 00:00:35,940 It will download them and install the software packages it needs, and 9 00:00:35,940 --> 00:00:40,000 then when it's complete, it'll print some post install directions for you. 10 00:00:41,550 --> 00:00:43,560 You should make sure to read those directions. 11 00:00:43,560 --> 00:00:47,538 In this case, there's one command in particular that we need to be sure to 12 00:00:47,538 --> 00:00:51,851 run to actually start postgresql and that's brew services start postgresql. 13 00:00:51,851 --> 00:00:53,174 I'll just copy and paste it here.
