无法使用 capistrano 3 或远程服务器 rbenv ruby： Capistrano Version: 3.6.1 (Rake Version: 11.3.0)

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

Capfile

# Load DSL and set up stages
require "capistrano/setup"

# Include default deployment tasks
require "capistrano/deploy"

# Extra rails commands
require "capistrano/rails/collection"

# Include tasks from other gems included in your Gemfile
#
# For documentation on these, see for example:
#
#   https://github.com/capistrano/rvm
#   https://github.com/capistrano/rbenv
#   https://github.com/capistrano/chruby
#   https://github.com/capistrano/bundler
#   https://github.com/capistrano/rails
#   https://github.com/capistrano/passenger
#
# require 'capistrano/rvm'
require 'capistrano/rbenv'
# require 'capistrano/chruby'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
# require 'capistrano/passenger'

# 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',
}

【问题讨论】：

不知道是不是因为你有ssh_options，查看capistrano-rbenv 源码-> github.com/capistrano/rbenv/blob/master/lib/capistrano/tasks/…
顺便说一句，您使用的是哪个 gem 版本？
@faron 在这种情况下，唯一改变的是我被要求登录，除了上面列出的问题之外，我还看到了一条附加消息：Text will be echoed in the clear. Please install the HighLine or Termios libraries to suppress echoed text.
Capistrano 版本：3.6.1（Rake 版本：11.3.0）

【解决方案1】：

似乎对于 capistrano 和非交互式 shell，rbenv 配置必须放在 .bashrc 而不是其他 bash 配置文件中。

就我而言，我搬家了

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

到.bashrc 解决了我的问题。
