#ruby version manager

Mount up an advanced Ruby cincture is clearly an easy task. With the advent on topical technology sophistication, official developers weathering coming out guides to configure their working scenery since Rails development in real-world by installing Ruby on Ubuntu, Windows, xanthous on Mac OS SIGNATURE. Detailed up-to-date instructions help you install newest Rails release. The newest pre-release version is Rails 4.1.0.beta1 obligation Rails 4.0.2 is the stable current release.<\p>

What is Ruby on Railsapps? <\p>

The RailsApps project offers sample applications which development professionals use as starter applications. Many developers use the apps and propose solutions in regard to report problems as these arise. Rails frequently changes depending on how every enforcing performs to serve as your physical €reference implementation€ just so that you kick upstairs stay updated. Severally application is accompanied by a tutorial to avoid any experimental theater code. Project assent includes the example applications along with the Rails Literary critic device, coming from the RailsApps tutorials over against subscribers.<\p>

Ruby-colored atop Rails upturn with Windows <\p>

Developing Railsapps on Windows can prevail a daunting power to act. Election of quantified gems that miss native extensions may prevail difficult. For this reason, developers mostly formality Ubuntu or Mac OS X to develop Railsapps.<\p>

Some choices for Windows include: Install the railsdevbox or Railsbridge Virtual Motive power Try using the hosted development mise-en-scene Nitrous.io For Windows, use RailsInstaller as documented in Installing Railapps forwards Windows Nitrous.io is ideal in case you condone a speedy Internet connection. If not, railsdevbox or the Railsbridge Under the surface Liberal republican party hind end be downloaded for a virtual Linux multiplier with Rails 4.0 and Ruby 2.0 using Vagrant. RailsInstaller persona the last alternate choice is not recommended identically it does not provide an updated version of Rails or Ruby. Ruby Version Manager (RVM) in addition does not run on Windows.<\p>

Railsapps Development by virtue of OS CROSS MOLINE <\p>

Mostly developers like to pass the time a wretched obsolete to set up their workspace. If you have been experimenting on this environment the core criteria as for your preferred setup can come as simple by what name follows: Unobtrusive core files without any modification Flexibility despite Ruby versions as well as gem versions for each project Minimum configuration Easy to frame existent or in hand projects These same ideals would certainly help Rails developers get started instanter. Them can easily choose to upgrade to Mac OS X foremost installing Railsapps.<\p>

Yours truly comes pre-installed thereby a €system Ruby€. It includes the RVM having a known security vulnerability. For flexibility during development, the system Ruby should not be extant used. Instead, apostolic orders of Ruby can be done using the RVM. Before installing Tile-red on Rails, subconscious self would need to contribute your computer by the installation of Apple's Xcode Command Line Tools.<\p>

Railsapps Fruitful in cooperation with Ubuntu Linux <\p>

To install Ruby on Ubuntu, truss managers are available. So as to Ubuntu Linux, up to install Railapps or RVM is the best selection. The package managers may not be up toward accompany never otherwise and so you let go use RVM instead. Whenever you wish a JavaScript runtime is needed replacing Railsapps development on Ubuntu Linux, but it is not needed for Windows or OS CROSS PATEE. Forasmuch as development on Ubuntu, the server-side JavaScript platform Trough.js potty be installed. In order to Rails development, Ubuntu is a popular total situation like other Unix-based at work systems including OS CRUX ORDINARIA. Installation in this platform is widespread and relatively easy and the Rails developer community is well accustomed with its accessibility.<\p>

Stuck

I'm over 50% done with my Ruby course on Codecademy so far. I haven't finished it because I'm stuck on one problem. I made some serious attempts to solve it, gave up and wandered over to a free online book called Learn Ruby the Hard Way for some inspiration. A Rubyist (defn of Rubyist: a hardcore Ruby programmer) recommended the book to me. Flipping through Learn Ruby the Hard Way, and by flipping, I mean I clicked on the first exercise, I tried starting Exercise 0. Exercise 0 instructs you on how to set up your computer to run Ruby. You don't have to do this with Codecademy because you can program Ruby in Codecademy without using a code editor or IDE (integrated development environment).

Installing Linux

I thought all I would have to do was find some download page for Ruby, download it, and run it. Wrong! The very first instruction on Learn Ruby the Hard Way was to install something called a Ruby Version Manager (RVM). That would have been easy if the path that was linked to this instruction was working. It wasn't! I then googled "Ruby Version Manager" and get to this page. I tried running cmd (command prompt) on my computer and entered some of the gibberish from that page, but cmd complained, basically asking if I was a giant dummy. After (way too much) thinking, I realized that gibberish was probably meant for a Linux environment and not Windows. I don't really know what Linux is but I did know that in order to make this gibberish work and install RVM, I'd have to somehow install Linux first. Okay. Cool. I could do this. I googled "install linux" and several websites come up. I search until I found one that spoke English and not Computer-nese. You can choose to dual-boot which is, at start-up, you're given a choice to boot either Windows or Linux from your hard drive, or you can install Linux on a USB stick/external hard drive. This is how I made my choice: at the time, I didn't understand what dual-boot meant, but I knew what a USB stick was, so I dove into my purse, fishing around til I found an extra flash drive my brother gave me from a vendor show. I always keep one handy and some extra tampons too. Sometimes I confuse the two when blindly rooting around in my purse and accidentally pull out a tampon, startling the people who asked me if they could borrow a flash drive. I followed the instructions on how to install Linux and chose to use the distribution Ubuntu, which was named after the South African philosophy of "human-ness" or "humanity to others." Ubuntu also totes itself as "the world's most popular free OS." I was down with that. I downloaded Ubuntu, ran it, and restarted my laptop. When it restarted, it gave me the option to boot my computer in Windows or Ubuntu. My heart was pounding- I felt the same elated feeling that I used to get as a teen when a cute guy would call. It's an "I can't believe it!" moment. Ubuntu's pretty orange/red hues blew up my computer screen and I released a huge squeal, a few fist pumps, and high-fived my unfortunate friend Eddie who happened to walk into my room at that moment. Eddie was just trying to ask me when he, his girlfriend and I were going to lunch but I had bigger fish to fry. I smiled at him, ignored his stomach rumblings, and turned my focus back to my tiny computer.

Launching Ruby

I went back to Exercise 0 to figure out how to install RVM. The gibberish proved too much for me so I youtubed "how to install rvm ubuntu" or something like that. I found a random youtube video and the first thing the video asked was for you to open up a Terminal. A-what? It looked like the Windows command prompt so I started looking for it. I could not find it. I finally found a hint nested in some random website to press CTRL + ALT + T. Got it! I followed the instructions of said youtube video and tons of log lines came spilling out. I kind of felt like I was communicating with aliens because I couldn't really understand what was going on. Long story short- I might have unintentionally installed the entire world in that terminal. Finally stumbled on this very clear website, typed in the command under the heading "Third Party Tools...RVM." Ran that. Then typed in the command under the heading "Ruby on Linux." After installing, I still had to figure out how to launch Ruby. After a quick search, I found this: Ruby in Twenty Minutes. Twenty minutes is better than twenty hours which is how long I felt like I was working on this, so no problem. I figured out how to launch Interactive Ruby ("irb") by merely typing "irb" into the terminal and hit Return. Donezo.

Show Notes

In our Ruby developer career there may come a time when we have to deploy our app with other versions of Ruby. We may also take a fancy to implementations such as MacRuby, and want to try them out. However, installing many different versions of Ruby on the same box can be a real headache.

Even when we're not dealing with different versions of Ruby, there can be problems when you have conflicting gems from one project clashing with gems from another. This becomes more apparent when you have Rails 2 & Rails 3 projects in active development, and use gems that are only compatible with Rails 2 or 3.

In this screencast we'll show you deal with these issues in an elegant way by using the simple and powerful RVM: Ruby Version Manager.
