无法加载此类文件--bundler/setup (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。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。”。

然后我cat /var/log/nginx/error.log，我发现这行：

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)

我已经安装了捆绑器

$ bundler -v
Bundler version 1.9.2

这是我的 gem 环境：

有人遇到过同样的问题吗？ 谢谢

Answer 1

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

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

你可以用命令检查这个

$ which ruby

该命令的输出应该是你应该为passenger_ruby输入的那个

如果您还没有安装 bundler，请继续运行 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;
}

Answer 2

您需要生成binstubs 来解决问题：

bundle install --binstubs

Answer 3

尝试：

bundle exec passenger start ...

Answer 4

正如 karlingen 所说，问题是 PATH 问题的结果，但是如果您使用的是 RVM，您将希望通过另一种方式获得正确的 ruby​​ 路径...

最好按照乘客自己的指南查找此信息：
