后缀管道邮件到 ruby 脚本：'require GEM_NAME' 不加载宝石

Question

我正在尝试设置 postfix，它将收到的邮件通过管道传送到 ruby 脚本。我创建了一个用户 deploy，它运行来自 postfix/master.cf 的脚本文件。当邮件收到 postfix 调用并执行 ruby 脚本但 require 'resque' 不会在该脚本中加载 resque gem。这是来自 /var/log/mail.log.

/etc/postfix/master.cf:

这里是 /var/www/mail_getter/email_receiver.rb:

#!/home/deploy/.rvm/rubies/ruby-2.5.1/bin/ruby
puts 'email receiver......'
require 'rubygems'
require 'resque'
require 'redis'

class EmailReceive
  @queue = :incoming_email_queue

  def initialize(content)
    Resque.enqueue(EmailReceive, content)
  end
end
EmailReceive.new($stdin.read)

注意：我也尝试使用 #!/usr/bin/env ruby。

这里是 /etc/postfix/aliases:

myservice:      deploy

这里是 /etc/postfix/main.cf:

myhostname = mail.mailet.in
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydomain = mailet.in
mydestination = $myhostname, $mydomain, ubuntu-s-1vcpu-1gb-sfo2-01, localhost.localdomain, localhost
relayhost = 
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all

header_checks = regexp:/etc/postfix/header_checks

这里是 /etc/postfix/header_checks:

/To:.*@mailet.in.*/ FILTER myservice:

这是 rvm list 输出：

 =* ruby-2.5.1 [ x86_64 ]
   ruby-2.7.0 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

注意：我也尝试从绝对路径要求 gems。

我在从 postfix 调用脚本时使用 wrappers 目录中的 ruby 解决了这个问题。

/etc/postfix/master.cf 的有效配置：

 myservice unix    -       n       n       -       2       pipe
  flags=XhqFBR user=deploy argv=/home/deploy/.rvm/wrappers/ruby-2.5.1/ruby /var/www/mail_getter/email_receiver.rb
