If you're using macOS Catalina or later, then you should have Ruby 2.6.3, that's what's installed by default. Ruby on Rails 6 requires Ruby version 2.5 or later. Ive adding the neo4j gem into my gemfile as well as neo4j-core , neo4j-ruby-driver.- Once we have Homebrew installed, the next step is to ensure that we have a compatible version of Ruby that we can use with Ruby on Rails. The process is simple just download, click next-next-next and you are doneHi I am trying to install mysql2 gem in MacBook M1 Big Sur. Each installer includes all of the software necessary to run out of the box (the stack). Bitnami Ruby Stack Installers Bitnami native installers automate the setup of a Bitnami application stack on Windows, Mac OS and Linux.Your project may depend upon having certain versions of Ruby, so it's better if we can control and manage our own version of Ruby, and that's what we're going to see how to do. It's great to have that version of System Ruby there to get us started, but it's also not a great idea to rely on it, after all, if Apple updates the operating system, the version of Ruby that's included would be upgraded as well, and that may not be something that you want to do. There may not be a system, you may have to install something to begin with. It is notable that that in the macOS Catalina release notes, Apple warns that future versions of the operating system may not include Ruby by default. This is also referred to as System Ruby, a version of Ruby that Apple provides with the operating system.

Now if I type that, it's going to go back out and get the package for rbenv and download it. So, now I'll say brew install and then rbenv, with E-N-V. It's a small file in the user directory where you can put configurations and those configurations get run every time we open up a new window in terminal. If you don't have it, don't worry about it. Now from that directory, if I type ls, space, dash la, we'll get a list of the files and you'll see that I have a file here called bash profile. First, let's make sure that we're in our user directory using cd, space, and the tilde symbol. So, in order to do that, I'm going to go in and edit a configuration file. At this time, we want to initialize it, but we don't want to just initialize it this one time, we want the initialization to happen every time we launch a new window. Get windows with photoshop cs6 for macNow you can see I've already got a few configurations in here. Make sure you spell it correctly. Bash, underscore, profile. I'm going to type nano, which is a small little text editor program, and then space. But it's going to run it as a command every time that I open up this window. What that's going to say is tell rbenv to initialize. None of those are really that important, but what I do want to do is come down here and add a new line and this is important, I'm going to do eval, and then a space, and then inside double quotes, a dollar sign and parenthesis, rbenv, space, init, space, dash, and close the parenthesis and close the double quotes. And I've got something here that just takes away some warnings that it gives me about using the z shell instead of the bash shell. I've got an alias here so that I can have a keyboard shortcut ll, it's going to be the same thing as typing ls with a few options. So that should've initialized rbenv for us. Now, in order to get things started off, you'll either close this window and open a new one, or I can type source.bash_profile and it will run it for the first time. Bash_profile and hit return. It'll ask me where I want to save it, make sure that the name is correct, it's spelled correctly. It'll ask me if I want to save my changes and I'll type a Y for yes. You don't need to worry about these specialized versions. The main ones are going to be right up here, that's just numbers. There's a whole bunch of different ones there. We get a long list of all the versions of Ruby that it knows about. That's a command you're always going to run every time you install a new version of Ruby. When it's finally done, you want to make sure that you type rbenv, space, rehash. It'll take a few minutes for it to install. So to install, I would just type rbenv and then space, install, and then 2.6.5. Anything you use is fine, don't worry about it, as long as it's newer than 2.5, you're fine. So that's going in and I'l switch it, I say ruby -v again, now I'm using Ruby 2.6.5, and rbenv versions. In order to switch that star and to switch versions of Ruby, I have to use another command, rbenv, global, and then the name that I want, in this case it's 2.6.5. If I type ruby -v, it still tells me to pass the version of Ruby I'm using. Notice that there's a star next to system. And we can see that I have two versions installed, I have that System Ruby and I have 2.6.5. Then we're going to type rbenv versions to see the versions that we have installed. But now, I have a good updated version of Ruby to use with my Ruby analyze project. So I can set them globally or on a project by project basis. There are the global kind here, but there's another one that rbenv local, followed by, let's say system, and that will tell the current directory that I'm at or the current project that I'm in to use a certain version of Ruby, local 2.6.5, we tell it to use this newest version inside that project. And as I said, you can install multiple versions, and you can even have different projects point to different ones. Now the old Apple version is still there, every time we update our operating system, Apple can update it, but we're using a version that we have installed.
