在部署时找不到 rake-11.3.0（Capistrano Nginx Passenger）

Question

• 最近将旧的 Web 应用程序更新到 Rails 4.2.7.1 和 Ruby 2.3.1（它与 Rails 3 和 Ruby 1.9 一起使用）。
• 使用 rvm 在生产环境中的 nginx-passenger 服务器上运行应用程序。
• 更新了生产中的RVM和ruby，并将新的ruby版本设置为 默认。
• 与 Capistrano 一起部署。

应用程序无法运行，来自 nginx 日志：

更新

• 在生产服务器中运行“Bundle”我可以看到 rake-11.3.0 已安装。

• 阅读有关宝石组的建议链接。

• 看来所有gem都安装在gemset 2.3.1@default中

• 而且，阅读错误日志，该乘客正在使用 ruby-2.1.3@global gemset，它没有安装正确的 gems。

  现在，我必须更改乘客宝石集配置以使用正确的“默认”宝石集。有什么帮助吗？

Answer 1

尝试：

bundle exec rake 'option'

Answer 2

问题已解决，这是 Nginx-passenger 配置的问题。

nginx.conf 文件指向 ruby 2.1.3（我使用的 ruby 的先前版本），所以我简单地将这一行替换为：

passenger_ruby /home/deploy/.rvm/wrappers/ruby-2.3.1/ruby;
