ruby-on-rails - 无法加载此类文件 -- 捆绑程序/设置 (LoadError) ||在 Ubuntu 12.04 x32 上部署

Question

我尝试在 Ubuntu 12.04 x32 上使用 Nginx 部署我的 rails 应用程序，乘客。一切都完成后，我访问了我的 rails 应用程序，但它告诉我“我们很抱歉，但出了点问题。”。

那么我 cat /var/log/nginx/error.log ，我发现这一行:

Message from application: cannot load such file -- bundler/setup (LoadError)

我使用 rvm 和 rbenv

$ ruby -v
ruby 2.0.0p643 (2015-02-25 revision 49749) [i686-linux]
$ rbenv versions
system
* 2.0.0-p643 (set by /home/thomas/.rbenv/version)

我已经安装了 bundler

$ bundler -v
Bundler version 1.9.2

这是我的 gem 环境:

Answer 1

你肯定有一些 PATH 问题。内/etc/nginx/nginx.conf ，对于乘客，您应该指向安装了 bundler 的 ruby​​ 版本。

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /home/thomas/.rvm/wrappers/default/ruby;

您可以使用以下命令检查这一点

$ which ruby

该命令的输出应该是您应该为 passenger_ruby 输入的输出。

如果你还没有安装 bundler 继续运行 gem install bundler
还要确保在服务器块中设置环境变量:

server {
  listen 80 default;
  server_name blog.wall2flower.me;
  root /var/www/blog/current/public;
  passenger_enabled on;
}
