You'll be asked to setup a new user for Ubuntu. Remember this password as it's what you'll use later on when installing packages with sudo. You've now got a Ubuntu terminal on Windows.
You'll use this to run your Rails server and other processes for development. Installing with rbenv is a simple two step process. We'll be using Git for our version control system so we're going to set it up to match our Github account. If you don't already have a Github account, make sure to register. It will come in handy for the future. Replace my name and email address in the following steps with the ones you used for your Github account. The next step is to take the newly generated SSH key and add it to your Github account.
You want to copy and paste the output of the following command and paste it here. Since Rails ships with so many dependencies these days, we're going to need to install a Javascript runtime like NodeJS and a package manager called Yarn. If you're using rbenv, you'll need to run the following command to make the rails executable available:. Now that you've installed Rails, you can run the rails -v command to make sure you have everything installed correctly:. If you get a different result for some reason, it means your environment may not be setup properly.
Rails ships with sqlite3 as the default database. Chances are you won't want to use it because it's stored as a simple file on disk. There is a lot of documentation on both, so you can just pick one that seems like you'll be more comfortable with.
As part of the installation process, you'll set the password for the root user. When I try downloading the source code to my Mac, rails won't work and I get dozens and dozens of errors when I try to start the server.
There are way too many to even post here I also tried setting up a new app and painstakingly copying and pasting the files from the source into the new app after it complained numerous times that it could not find the rails server. Now it continues kvetching about syntax errors and dependencies in a dozen or so files and complaining about my gems.
I did properly update the database yaml file and have tried updating my gems and running bundle many, many times but the spaghetti bowl of errors never seems to resolve much.
This is the latest Rails 3 version of the app so why would it not work and why does it seem to think that half the gems are deprecated? Other people don't seem to be getting these types of errors. I'm clearly missing something that is plainly obvious to the rest of the world and have somehow majorly screwed up the installation. How does the process of downloading a complete app differ from installing a plugin? I've never had this much trouble with plugins.
Does anyone know of an idiot-proof checklist for downloading, installing and setting up this app? After three months of trying to make this work, I am beyond frustrated. Here are the steps I took on Ubuntu, mostly in this order. Not completely satisfied? You can customise the output. Install the rails-erd gem, load your models, and execute If Rails ERD doesn't work like you expected it to, don't give up immediately.
First of all, check if you can generate a graph without rendering it It is a lightweight Ruby Version Management Tool. The rbenv provides an easy installation procedure to manage various versions of Ruby, and a solid environment for developing Ruby on Rails applications.
First of all, we have to install git - core and some ruby dependences that help to install Ruby on Rails. Use the following command for installing Rails dependencies using yum. Now we will install rbenv and set the appropriate environment variables. Use the following set of commands to get rbenv for git repository. Before installing Ruby, determine which version of Ruby you want to install. We will install Ruby 2. Use the following command for installing Ruby.
Ruby provides a keyword gem for installing the supported dependencies; we call them gems. If you don't want to install the documentation for Ruby-gems, then use the following command. Thereafter, it is better to install the Bundler gem, because it helps to manage your application dependencies. Use the following command to install bundler gem.
