Linux Deploy Rails3 with Ruby1.9.2 (5) Fix the Error Messages

Linux Deploy Rails3 with Ruby1.9.2 (5) Fix the Error Messages

1. Sprockets: Environment # path is deprecated
We have 2 ways to solve this, it is harmless warning message
One way is to upgrade our rails from rc5 to rc8.
> Gem install rails-v = 3.1.0.rc8
> Vi Gemfile
Gem 'rails ', '3. 1.0.rc8'
> Bundle update
The other way is to put this gem 'sprockets ', '2. 0.0.beta.15' into our Gemfile.
> Bundle update sprockets

2. Insecure world writable dir
/Home/luohua /. rvm/rubies/ruby-1.9.2-p290/lib/ruby/gems/1.9/gems/passenger-3.0.8/lib/phusion_passion/ platform_info/operating_system.rb: 98: warning: insecure world writable dir/home/luohua /. rvm/rubies/ruby-1.9.2-p290/bin in PATH, mode 040777

> Sudo chmod go-x-R/home/luohua/. rvm/rubies/ruby-1.9.2-p290/bin
> Sudo chmod go-w ~ /. Rvm

3. something went wrong
I can see some message on the pages as follow:
We're sorry, but something went wrong.
We 've been notified about this issue and we'll take a look at it shortly.

Check the project log directory and the production. log

That is because of the 'sprockets' version. I hate this and redhat4. I just change to rc8 way, but this problem still there.

I clean up all the directory, and download my project again. everything is fine then. I think I may benefit from update the system to rc8, and without anything changes in Gemfile. so just upgrade the system, but do not change your Gemfile, just use the old one as follow:
Gem 'rails ', '3. 1.0.rc5'

# Bundle edge Rails instead:
# Gem 'rails ',: git => 'git: // github.com/rails/rails.git'

# Gem 'sqlite3'

# Gem 'mysql', '2. 8.1'

Gem 'mysql2'

Gem 'execjs'

# Gem 'therubyracer'

Gem 'lib8'

4. How to make comments in erb files
This is not deployment issue, but development issue. If we want to make large comments in erb files, we can do like this:
<% If false %>
Balababalalalala
Blablalalalalalalalalalaladkala
<% End %>
