无效命令'PassengerAppRoot'，可能由服务器配置中未包含的模块拼写错误或定义

我已按照Installing Passenger + Apache on a Linux/Unix production server for Node.js apps + Red Hat 6 / CentOS 6 (with RPM)中的每个步骤进行安装，一切正常但是当我尝试在我的centos 6服务器上使用WHM来托管我的botkit bot的虚拟主机中配置我的子域时，我收到此错误：

“/ usr / local / apache / bin / httpd”命令（进程27088）在结束时报告错误号1 . 在/usr/local/apache/conf/includes/post_virtualhost_2.conf.tmp文件的第9行检测到配置问题：无效的命令'PassengerAppRoot'，可能拼写错误或由服务器配置中未包含的模块定义--- / usr / local / apache / conf / includes / post_virtualhost_2.conf.tmp --- 3 ServerAlias subdomain.mydomain.com 4 ServerAdmin adminserver@mydomain.com 5 6 7＃告诉Apache和Passenger你的应用程序的代码目录是8 DocumentRoot / var / www / MyApp / Code / public 9 ===> PassengerAppRoot / var / www / MyApp / Code <=== 10＃Error logging 11 ErrorLog logs / subdomain-error_log 12 CustomLog logs / subdomain-access_log common 13 14＃告诉乘客你的app是一个Node.js应用程序15 PassengerAppType节点--- /usr/local/apache/conf/includes/post_virtualhost_2.conf.tmp ---

这是我的配置：

<VirtualHost *:80>
    ServerName www.subdomain.mydomain.com
    ServerAlias subdomain.mydomain.com
    ServerAdmin adminserver@mydomain.com


    # Tell Apache and Passenger where your app's code directory is
    DocumentRoot /var/www/MyApp/code/public
    PassengerAppRoot /var/www/MyApp/code
    #Error logging
     ErrorLog logs/votebot-error_log
     CustomLog logs/votebot-access_log common

    # Tell Passenger that your app is a Node.js app
    PassengerAppType node
    PassengerStartupFile bot.js

    # Relax Apache security settings
    <Directory /var/www/MyApp/code/public>
      Allow from all
      Options -MultiViews
      # Uncomment this if you're on Apache >= 2.4:
      #Require all granted
    </Directory>
</VirtualHost>

我试图删除配置并通过.htaccess传递：

PassengerEnabled on
PassengerAppRoot /var/www/MyApp/code
SetEnv NODE_ENV production
SetEnv NODE_PATH /usr/lib/node_modules
PassengerAppType node
PassengerStartupFile bot.js

但它仍然无法正常工作 . 我最近检查过并在验证乘客时收到以下消息：

* Checking whether this Passenger install is in PATH... ✓
 * Checking whether there are no other Passenger installations... (!)

   You are currently validating against Phusion Passenger 5.1.8, located in:

     /usr/bin/passenger

   Besides this Passenger installation, the following other
   Passenger installations have also been detected:

     /usr/local/rvm/gems/ruby-2.4.1/bin/passenger

   Please uninstall these other Passenger installations to avoid
   confusion or conflicts.

问题是我不知道卸载/usr/local/rvm/gems/ruby-2.4.1/bin/passenger的步骤是什么 .
