我尝试使用knife-solo在Vagrant上安装Ruby 2.0.0-p353。
当我以root和vagrant身份登录时,ruby -v
返回Ruby 2.0.0-p353。
但是,当我在Rails项目中运行bundle install
时,会显示以下语句:
Your Ruby version is 1.8.7, but your Gemfile specified 2.0.0
Ruby的默认版本是1.8.7,所以我认为bundle install
指的是这个。
我该怎么做才能解决这个问题?
$ cat site-cookbooks/ruby/recipes/default.rb
group 'rbenv' do
action :create
members 'vagrant'
append true
end
git '/usr/local/rbenv' do
repository 'git://github.com/sstephenson/rbenv.git'
reference 'master'
action :checkout
user "#{node.user}"
group 'rbenv'
end
directory '/usr/local/rbenv/plugins' do
owner "#{node.user}"
group 'rbenv'
mode 0755
action :create
end
template '/etc/profile.d/rbenv.sh' do
owner "#{node.user}"
group "#{node.user}"
mode 0644
end
git '/usr/local/rbenv/plugins/ruby-build' do
repository 'git://github.com/sstephenson/ruby-build.git'
reference 'master'
action :checkout
user "#{node.user}"
group 'rbenv'
end
execute 'ruby install' do
not_if "source /etc/profile.d/rbenv.sh; rbenv versions | grep #{node.ruby.version}"
command "source /etc/profile.d/rbenv.sh; rbenv install #{node.ruby.version}"
action :run
end
execute 'ruby change' do
command "source /etc/profile.d/rbenv.sh; rbenv global #{node.ruby.version}; rbenv rehash"
action :run
end
$ cat site-cookbooks/ruby/attributes/default.rb
default['user'] = 'root'
default['ruby']['version'] = '2.0.0-p353'
$ cat site-cookbooks/ruby/templates/default/rbenv.sh.rb
export RBENV_ROOT=/usr/local/rbenv
export PATH="$RBENV_ROOT/bin:$PATH"
eval "$(rbenv init -)"

请执行以下步骤来解决问题:
确保以下命令返回正确版本的ruby:
$ rbenv versions
system
2.0.0-p353
$ rbenv local
ruby-2.0.0
$ rbenv version
2.0.0-p353
确保获取ruby的版本是正确的:
$ bundle exec ruby -v
ruby 2.0.0-p353 (2013-11-22 revision 43784) [x86_64-linux]
如果你获得了无效的ruby版本,你可以通过调用shell来验证问题是否在bundler
中:
$ bundle exec ruby -v
ruby 1.8.7
$ which bundle
/usr/bin/bundle
它表示将调用系统ruby来继续执行ruby脚本。
重新安装bundler,然后确保现在的ruby有效:
$ gem install bundler
$ bundle exec ruby -v
ruby 2.0.0-p353 (2013-11-22 revision 43784) [x86_64-linux]
