当我从我的应用程序目录中运行 rackup 时，它工作正常：

walkraft@li234-166:~/discourse$ rackup config.ru
Flushing redis (development mode)
/home/walkraft/.rvm/gems/ruby-1.9.3-p374/gems/activesupport-3.2.11/lib/active_support/dependencies.rb:251:in `block in require': iconv will be deprecated in the future, use String#encode instead.
/home/walkraft/discourse/vendor/gems/message_bus/lib/message_bus.rb:130: warning: already initialized constant ENCODE_SITE_TOKEN
>> Thin web server (v1.5.0 codename Knife)
>> Maximum connections set to 1024
>> Listening on 0.0.0.0:9292, CTRL+C to stop

但是，如果我尝试从这个目录之外运行 rackup：

walkraft@li234-166:~$ rackup discourse/config.ru

当我不在根目录中时，如何运行 rackup？

如果您不想手动到 Discourse 根文件夹，那么为什么不直接在 rackup文件cd中添加一个修复：config.ru

# Insert as first line in config.ru
Dir.chdir(File.dirname(File.expand_path(__FILE__)))

实际上，这不是问题rackup; 你的代码有问题。

你有

require './lib/discourse_plugin_registry'

某处。这并不理想。它应该是这样的：

require File.expand_path('../../lib/discourse_plugin_registry', __FILE__)

您拥有它的方式，它显式地使用当前目录，并且无论您做什么rackup，直到您更改当前目录 - 它都不起作用。
