Question

我是linux和rails的新手，我正在尝试启动并运行开发服务器。我已经安装了ruby / rails并让它在localhost：3000下运行。我可以创建一个rails应用程序并让它运行。

然后我安装了apache 2 / passenger。当我尝试命中机器的IP地址时，我收到以下错误：

It looks like Bundler could not find a gem. Maybe you didn't install all the gems that this application needs. To install your gems, please run:

bundle install

If that didn't work, then the problem is probably caused by your application being run under a different environment than it's supposed to. Please check the following:

Is this app supposed to be run as the a-cjstewar user?
Is this app being run on the correct Ruby interpreter? Below you will see which Ruby interpreter Phusion Passenger attempted to use.

-------- The exception is as follows: -------

这是我的app1.conf文件：

       AllowOverride None
       # MultiViews must be turned off.
       Order allow,deny
       Allow from all
    </Directory>
</VirtualHost>

ruby -v

ruby 2.4.0p0 (2016-12-24 revision 57164) [x86_64-linux]

rails -v

Rails 5.1.2

apache2 -v

Server version: Apache/2.4.18 (Ubuntu)

乘客-v

Phusion Passenger 5.1.6

我不知道从哪里开始。任何帮助表示赞赏！

Answer 1

您似乎正在使用与您认为不同的Ruby运行应用程序。

为了获得你说你的应用应该运行的Ruby 2.4.0p0，你应该找到Ruby所在的位置

which ruby

然后，您可以使用PassengerRuby中的<VirtualHost>指令将该可执行文件设置为要使用的Ruby：

<VirtualHost *:80>
    PassengerRuby: /path/to/ruby
    # other stuff
</VirtualHost>

查看the documentation for the PassengerRuby directive了解详情。
