如何從Chef和Vagrant調試RVM設置？

Question

我在Vagrant虛擬機上用Chef-solo獲得了RVM設置，但是我很困惑爲什麼在rails項目中找不到bundler。

因此，在配置後我看到：

 
Last login: Thu Oct 4 15:23:58 2012 from 10.0.2.2 
vagrant@vm:~$ ruby -v 
ruby 1.9.3p327 (2012-11-10 revision 37606) [x86_64-linux] 
vagrant@vm:~$ gem list 

*** LOCAL GEMS *** 

bigdecimal (1.1.0) 
bundler (1.3.2) 
daemon_controller (1.1.1) 
fastthread (1.0.7) 
io-console (0.3) 
json (1.5.4) 
minitest (2.5.1) 
passenger (3.0.18) 
rack (1.5.2) 
rake (10.0.3, 0.9.2.2) 
rdoc (3.9.4) 
rubygems-bundler (1.1.1) 
rvm (1.11.3.6) 

將項目目錄我看到：

 
vagrant@vm:~$ cd /www/vm/rails/current/ 
============================================================================== 
= NOTICE                  = 
============================================================================== 
= RVM has encountered a new or modified .rvmrc file in the current directory = 
= This is a shell script and therefore may contain any shell commands.  = 
=                   = 
= Examine the contents of this file carefully to be sure the contents are = 
= safe before trusting it! (Choose v[iew] below to view the contents)  = 
============================================================================== 
Do you wish to trust this .rvmrc file? (/www/vm/rails/current/.rvmrc) 
y[es], n[o], v[iew], c[ancel]> y 
mkdir: cannot create directory `/usr/local/rvm/gems/ruby-1.9.3-p327@vm': Permission denied 
gemset vm is not existing, creating. 
mkdir: cannot create directory `/usr/local/rvm/gems/ruby-1.9.3-p327@vm': Permission denied 
mkdir: cannot create directory `/usr/local/rvm/gems/ruby-1.9.3-p327@vm': Permission denied 

但現在，束不能再被發現了，我也有問題，激活RVM ...任何想法如何調試？

 
$ rvm use ruby-1.9.3-p327 
Please note that `rvm gem ...` was removed, try `gem ` or `rvm all do gem ` instead. (see: 'rvm usage')

爲了調試我用https://github.com/mpapis/rvm-binary/blob/master/cookbooks/binary/recipes/default.rb#L11：

class Chef::Resource::Script 
    def log_code command 
    if Chef::Config[:log_level] == :debug 
     code "{ #{command}; _ret=$?; echo \"Exit status was $_ret.\"; exit $_ret; } 2>&1 | 
tee /var/log/#{@command.to_s.gsub(/ /,"_")}.log; exit ${PIPESTATUS[0]}" 
    else 
     code command 
    end 
    end 
end 

，然後代替code使用log_code，這將節省日誌中/var/log/#{@command.to_s.gsub(/ /,"_")}.log

至於易於整合RVM與廚師檢查https://gist.github.com/sevos/5076747 ：

deploy_user = node[:deploy][:user] 
deploy_user_home = File.join('/', 'home', deploy_user) 
rvm_version = "head" 

execute "install_rvm_for_deploy_user" do 
    user deploy_user 
    command "curl -L https://get.rvm.io | bash -s #{rvm_version}" 
    environment "HOME" => deploy_user_home 
    creates "#{deploy_user_home}/.rvm" 
end 

node['buildpack']['ruby_versions'].each do |ruby_version| 
    execute "install_rvm_ruby_#{ruby_version}" do 
    user deploy_user 
    environment "HOME" => deploy_user_home 
    command "#{deploy_user_home}/.rvm/bin/rvm install #{ruby_version} --autolibs=3" 
    end 
end 

file "#{deploy_user_home}/.rvmrc" do 
    content 'export rvm_trust_rvmrcs_flag=1' 
    owner deploy_user 
    mode 0644 
end
