问题 Hi I am really new to linux. I am currently deploying an app on digital ocean so I am switching to linux ox temporarily. I did sudo apt-get install ruby 2.0.0 and installed correctly but when I do ruby-v I am getting the 1.8.7 version. I am sure that the old version is prepackaged with mint. How do I switch to ruby 2.0.0 in my bash profile or the linux startup files? 回答1: If you're new to linux I'd recommend using something like RVM (Ruby Version Manager) to install ruby. It makes it easier

问题 I would like to install the travis gem on a machine without ruby gems, and on which I don't have root. (I want to encrypt something for use with travis.) I decided to try to install rvm, because https://rvm.io/rvm/install suggests that it is an easy way to install ruby without root. However, I ran into problems right away: jgross@cagnode17:~$ \curl -L https://get.rvm.io | bash -s stable --ruby % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed

Rails 3 initializes extremely slow on Ruby 1.9.2

问题 I'm using RVM for managing environment, installed Ruby 1.9.2.p136 (i think its latest release.) and Rails 3, created gemsets and run bundler. everything working good so far but; Rails initalizes extremely slow when running commands, i.e. generate, destroy, rake etc. Takes about 30-45 seconds to complete command. This will never happens if use Ruby Enterprise Edition or Ruby 1.8.7 Why this happens. Any thoughts? Running on Ubuntu 10.10, RVM, Ruby 1.9.2, Rails 3 Thanks. 回答1: There is a thread

Zsh & RVM woes (rvm-prompt doesn't resolve)

由 一个人想着一个人 提交于 2019-12-03 05:32:58
I recently saw the light and changed over to Zsh. I naturally used Oh My Zsh to configure it, as I'm noobish. So, there are several themes that have an rvm-prompt included and here is were my problems began. Everytime I load Zsh I have to rvm reload or else rvm-prompt is not resolved ( zsh: command not found: rvm-prompt ). Note that it resolves fine after I reload. Also, and in line, when I go to a directory that has its own .rvmrc (other gemset) and then I come out of it, the same problem occurs; I'm left with having to reload Zsh again. I have RVM in $PATH set. I have [[ -s "$HOME/.rvm

How do I install Ruby gems when using RVM?

由 霸气de小男生 提交于 2019-12-03 05:31:59
问题 I set up RVM and used it to install Ruby and a few other libraries. As I was going through various tutorials and set-ups of other technologies like Rails, I began getting confused about what I should do via RVM and what I should just do as the tutorials suggest. One example is the RubyGems tutorial here: http://rubygems.org/pages/download Should I download that tar file they are talking about? Seems unnecessary since that is what I thought RVM was for. Do I even need RubyGems? What is that

How do I recompile a ruby with RVM?

由 牧云@^-^@ 提交于 2019-12-03 04:43:38
问题 I installed Ruby 1.9.3 with RVM, and it works fine. I then made some changes in a ruby C source file, and I want to recompile and re-install it so I can use the changes. I haven't found any kind of rvm recompile command however. 回答1: The problem with using rvm [reinstall|install] is that it will fetch and use precompiled binaries if it can find any. Sometimes, you really want to rebuild from source, probably because you're trying to use a more recent version of GCC (e.g. 4.8 or 4.9). The
