乘客一直在寻找错误的 ruby 版本

Question

我将 ruby 版本升级到 2.6.5。我使用 capistrano 将它部署到我的服务器。

但是我的 nginx 日志是这样说的：

App 9470 output: /bin/sh: 1: exec: /home/deploy/.rvm/gems/ruby-2.3.1/wrappers/ruby: not found
[ E 2022-01-27 12:34:23.7336 9450/Tc age/Cor/App/Implementation.cpp:221 ]: Could not spawn process for application /home/deploy/taddar/current: The application process exited prematurely.
  Error ID: d1f83ca0
  Error details saved to: /tmp/passenger-error-0KwZUf.html

[ E 2022-01-27 12:34:23.7393 9450/T9 age/Cor/Con/CheckoutSession.cpp:276 ]: [Client 1-1] Cannot checkout session because a spawning error occurred. The identifier of the error is d1f83ca0. Please see earlier logs for details about the error.

当我运行 ruby -v 我得到 2.6.5，但在上面你可以看到它正在寻找 2.3.1:

ruby -v
ruby 2.6.5p114 (2019-10-01 revision 67812) [x86_64-linux]

关于如何解决这个问题有什么想法吗？

在我的 deploy.rb 中，我设置了 ruby 版本。

set :rvm_ruby_version, '2.6.5'

我的 nginx.config 看起来像：

user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
        worker_connections 768;
        # multi_accept on;

        passenger_ruby /usr/bin/ruby2.6.5;

宾果成功了。感谢@razvans 和@engineersmnky 为我指明了正确的方向。

是的，我提到了 passenger_ruby，但它放错了地方。我不得不去 /etc/nginx/sites-available 并添加 passenger_ruby /path/to/ruby

要找出 /path/to/ruby 是什么，请使用 passenger-config about ruby-command 并使用 Command 处的值。

passenger-config about ruby-command
passenger-config was invoked through the following Ruby interpreter:
  Command: /home/deploy/.rvm/gems/ruby-2.6.5/wrappers/ruby

所以我的是

server {
 ....
 passenger_ruby /home/deploy/.rvm/gems/ruby-2.6.5/wrappers/ruby

您可能想知道您必须 ruby 的任何其他参考资料，以免它们相互冲突。一个有用的命令是：grep -rnw 'path' -e 'passenger_ruby'

这个文档对我帮助很大https://www.phusionpassenger.com/library/deploy/nginx/deploy/ruby/#determine_ruby_command
