使用nginx的乘客:无法加载此类文件 - bundler/setup(LoadError)

Question

只安装了一个版本的Ruby,我已经运行了gem install bundler && bundle install.

nginx conf

passenger_root /root/.gem/ruby/2.1.0/gems/passenger-4.0.52;
passenger_ruby /usr/bin/ruby;
server {
    listen 80;
    server_name example.com;
    root /srv/http/myrailsapp/public;
    passenger_enabled on;
    rails_env development;
}

错误日志

Answer 1

我一直在解决类似的问题.

我的问题是配置的passenger_ruby /usr/bin/ruby;哪个指向不正确的版本.我的解决方案是设置命令输出的路径which ruby

在服务器上我使用rvm.但是还有其他红宝石的存在.

首先尝试测试环境.转到应用程序目录并运行passenger start.如果服务器已准备好运行应用程序,这将向您显示.修复错误......

如果消息仍然这样说

cannot load such file -- bundler/setup (LoadError)

运行gem install bundler并重新检查.

然后在NGINX中将路径设置为从which ruby命令路径并重新启动应用程序.

你需要改变你的passenger_root价值观。就像文档中的这里一样

例如我的 nginx 配置：

...
  passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
  passenger_ruby /usr/bin/ruby;
...
