uninitialized constant Rack::URLMap::PATH_INFO

Hi,

currently I am trying to install redmine 3.0.3 on my bananian-router-board (similair a raspberrypi) but unfortunatelly without success. Therefore I hope you could help me.

I followed the generic installation guide and some others howtos to use ssl and install into a suburi "https://_ip_/redmine" but I don't kow... either nginx or thin do not work like expected as I get the message "502 Bad Gateway" in my webbrowser.

In the folder /var/run/thin is a redmine instance created:
srwxrwxrwx 1 thin web_001 0 Jun 11 12:19 redmine.0.sock=

my Problem now is:

Unexpected error while processing request: uninitialized constant Rack::URLMap::PATH_INFO

What do I have to do now?

As this while thing already took me several days I would be really happy about some help
thanks!

Hello, I migrated redmine from 2.6.0 to 3.2.0 and I have now exactly the same error as you.

Unexpected error while processing request: uninitialized constant Rack::URLMap::PATH_INFO

Redmine is always in Error 500, and no log in log/production.log

I don't know what to do... Did you find a solution ?

EDIT:

Here are debug logs of thin server :

RE: uninitialized constant Rack::URLMap::PATH_INFO - Added by cyber xndr almost 9 years ago

The issue is related to thin package version. Version that provided in ubuntu/debian repositories is too old. You should delete it using your packet manager and install thin directly via bundle install from your redmine directory. g++ will required for some dependencies in this case.

apt-get install g++
cd /var/www/redmine/
echo "gem 'thin'" >> Gemfile
bundle install --without development test

That fixes the problem for me. Notice also that thin command is not available anymore, so you should run it manualy from the /var/lib/gems/1.9.1/gems/thin-1.6.4/bin directory.

Thanks for the reply. It makes sense. I will try this.
:)

RE: uninitialized constant Rack::URLMap::PATH_INFO - Added by Bertrand Michas over 8 years ago

Hello,
All works now. Thanks to you :)

I would like to say that I had to install those dependencies on Debian Jessie in order to execute "bundler install":

apt-get install ruby ruby-dev g++ build-essential libmysqlclient-dev libmagick++-dev

After the "bundler install" thing, thin is compiled and the bin file is automatically placed in /usr/local/bin.
So if "/usr/local/bin" is in your PATH, you can simply run "thin start".

Then, I created a little bash script to generate a thin configuration for redmine:

#!/bin/bash

# VARIABLES
REDMINE_INSTALL="/var/www/redmine/latest" 

# Some folder creation
sudo mkdir /etc/thin
sudo mkdir /var/log/thin
sudo chmod 755 /var/log/thin

# conf thin for redmine
sudo thin config --config /etc/thin/redmine.yml --chdir $REDMINE_INSTALL --environment production --socket /var/run/redmine/sockets/thin.sock --daemonize --log /var/log/thin/redmine.log --pid /var/run/thin/redmine.pid --user www-data --group www-data --servers 1 --prefix /

# permissions www-data for redmine
sudo chown -R www-data:www-data $REDMINE_INSTALL/public
sudo mkdir -p $REDMINE_INSTALL/tmp/pdf $REDMINE_INSTALL/public/plugin_assets
sudo chown -R www-data:www-data $REDMINE_INSTALL/files $REDMINE_INSTALL/log $REDMINE_INSTALL/tmp $REDMINE_INSTALL/public/plugin_assets
sudo chmod -R 755 $REDMINE_INSTALL/files $REDMINE_INSTALL/log $REDMINE_INSTALL/tmp $REDMINE_INSTALL/public/plugin_assets

# permissions redmine.yml
sudo chown root:root /etc/thin/redmine.yml
sudo chmod 644 /etc/thin/redmine.yml

# socket thin
sudo mkdir -p /var/run/thin
sudo chown -R www-data:www-data /var/run/thin/

# socket redmine
sudo mkdir -p /var/run/redmine/sockets/
sudo chown -R www-data:www-data /var/run/redmine

And I use the following systemd.service to start / stop thin:

[Unit]
Description=A fast and very simple Ruby web server
After=syslog.target network.target

[Service]
Type=forking
User=www-data
Group=www-data
ExecStart=/usr/local/bin/thin start --all /etc/thin/
ExecReload=/user/local/bin/thin restart --all /etc/thin/
ExecStop=/usr/local/bin/thin stop --all /etc/thin
TimeoutSec=300

[Install]
WantedBy=multi-user.target

The last step is configuring Nginx but there is already many tutorials on this on the web.

All works perfectly now :)

Thanks again.
