rbenv

问题 I'm using rbenv to set the ruby version. ruby -v produces the expected 1.9.3 I can do gem install paperclip without a problem. However, when I do bundle install it says: Installing paperclip (3.1.2) Gem::InstallError: paperclip requires Ruby version >= 1.9.2. An error occured while installing paperclip (3.1.2), and Bundler cannot continue. Make sure that `gem install paperclip -v '3.1.2'` succeeds before bundling. but, ruby -v says I'm running 1.9.3. Is bundler runnign as sudo? Have anyone

问题 Using Ansible, how can I use the gem (or other) module to install a gem (in this case, bundler) such that I can run the following command without error? deployer@boxes-vm:~$ ~/.rbenv/bin/rbenv exec bundle install rbenv: bundle: command not found 回答1: Well, you can always use the bundle from the shims directory command: ${HOME}/.rbenv/shims/bundle install --deployment 来源： https://stackoverflow.com/questions/23133850/how-to-install-gems-for-rbenv-using-ansible

问题 My environment: Mac OS X v10.7.2 with Xcode 4.2.1 I am trying to build ruby 1.9.3 on Lion with Xcode 4.2.1. I understand there's an issue with the llvm-based gcc compiler that comes with Xcode 4.2.1. But I'm trying to work around it by following these instructions, http://goo.gl/Sc39g. I was able to get a little farther along, but then ran into these 2 problems: #error Please add -D_FILE_OFFSET_BITS=64 to your compile flags! fatal error: 'sys/statfs.h' file not found The complete configure

问题 You may think this is a classic "global" command question, but it is not. I can set ruby globally by this: rbenv global 2.5.1 However this makes ruby2.5.1 global for all users but not for the whole system. When an application in same server want to call ruby or access/pipe ruby, they get command not found error. I believe we should have to install or symlink to /usr/bin or /usr/local/bin or something... I couldn't find anything regarding to this. How can I make selected ruby version to be

问题 I have a Ruby/Rails devvelopment environment using rbenv, MRI Ruby (1.9.2-p290), rails 3.0.9, and SQLite3. I would like to port it to JRuby, but do it such that I don't have to do anything more than run "rbenv local jruby-1.6.4" and "rails server" in the root directory of the Rails application to use it with JRuby, and "rbenv local 1.9.2-p290" and "rails serer" to use it with MRI Ruby. I am aware that the gems to access SQLite are different for Ruby versus JRuby, but how do you write the

问题 To clarify, I'm using rbenv to manage my ruby versions. I was under the impression that binaries are managed as shims in their respective ruby version directory. Here is what my system shows when I run gem environment (I'm excluding the irrelevant parts): - GEM PATHS: - /Volumes/Data/nathan/.rbenv/versions/1.9.3-p194/lib/ruby/gems/1.9.1 - /Volumes/Data/nathan/.gem/ruby/1.9.1 Any reason for having two locations? Curious minds want to know. 回答1: I think I figured out the answer to this question

问题 I can't seem to find a way to switch versions of PHP quickly. Is there something equivalent to ruby version manager for php? I need to switch between 5.3 and 5.2 on OS X. 回答1: For PHP alternatives to RVM and rbenv, you have phpbrew, phpenv and php-version. Please be aware that I am the author of php-version so of course I prefer it as I wrote it to scratch my own itch (I wanted something minimal with command completion); however, phpenv is quite good as well. You would do well to use either.
