我的设置：

deploy.rb

set :rbenv_type, :user
set :rbenv_ruby, '1.9.3-p551' # same as in .ruby-version file
set :default_shell, '/bin/bash -l'
set :pty, true
within release_path do
    ruby_v = capture("which ruby")
    puts "Ruby version: #{ruby_v}"
end

# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }

config / deploy / staging.rb

set :ssh_options, {
    forward_agent: true,
    auth_methods: %w(password),
    password: 'xxx',
    user: 'xxx',
}

Answer 1

似乎使用Capistrano和非相互作用的外壳，RBENV配置必须放入.bashrc而不是其他Bash配置文件文件中。

在我的情况下，我移动了

export PATH="$HOME/.rbenv/bin:$PATH"
export TMPDIR="$HOME/tmp"
eval "$(rbenv init -)"

到.bashrc，这解决了我的问题。
