&lt;p&gt;&lt;b&gt;หน้าใหม่&lt;/b&gt;&lt;/p&gt;&lt;div&gt;หลังจากรัน script ตามปกติ จะมีปัญหาในคำสั่ง sudo rake gems:install&lt;br /&gt;
1) WARNING: &amp;#039;require &amp;#039;rake/rdoctask&amp;#039;&amp;#039; is deprecated.  Please use &amp;#039;require &amp;#039;rdoc/task&amp;#039; (in RDoc 2.4.2+)&amp;#039; instead&lt;br /&gt;
เกิดจาก rake ถ้า downgrade เป็น 0.8.3 warning จะหาย (เปลี่ยนจาก sudo apt-get install rake เป็น sudo gem install rake --version=0.8.3)&lt;br /&gt;
แต่ดูจาก solution อื่นๆแล้ว เหมือนว่าการทำอย่างนี้เป็นแค่การซ่อน warning ? อันนี้ผมไม่รู้เหมือนกัน&lt;br /&gt;
** ผมลองติดดูโดยไม่ได้ downgrade rake ก็พบว่าลงได้ตามปกติครับ = =&amp;quot; **&lt;br /&gt;
http://stackoverflow.com/questions/7993162/i-have-still-rake-rdoctask-deprecated-warning&lt;br /&gt;
&lt;br /&gt;
2) Uninitialized constant ActiveSupport::Dependencies::Mutex (NameError)&lt;br /&gt;
ใส่ require &amp;#039;thread&amp;#039; ก่อนบรรทัด require File.join(File.dirname(__FILE__), &amp;#039;boot&amp;#039;) ในไฟล์ Rakefile, script/server, config/environment.rb&lt;br /&gt;
http://stackoverflow.com/questions/5176782/uninitialized-constant-activesupportdependenciesmutex-nameerror&lt;br /&gt;
&lt;br /&gt;
3) rake aborted! undefined method `name&amp;#039; for &amp;quot;actionmailer&amp;quot;:String&lt;br /&gt;
เกิดจาก rubygems ถ้า downgrade เป็น 1.6.2 จะไม่มีปัญหา (sudo gem install rubygems-update -v 1.6.2 &amp;amp;&amp;amp; sudo update_rubygems)&lt;br /&gt;
การ downgrade rubygems ทำให้ gem ที่เคยลงมาหายหมด&lt;br /&gt;
http://www.redmine.org/issues/8325&lt;br /&gt;
&lt;br /&gt;
หลังจากลง rails ใหม่ คราวนี้ก็เรียบร้อยไม่พบปัญหาอะไรอีกครับ&lt;br /&gt;
&lt;br /&gt;
#########################################################################################&lt;br /&gt;
&lt;br /&gt;
สำหรับบางเครื่อง หลังติดตั้งไปไม่สามารถ start grader in grading env ได้ (กดแล้วไม่มี grader ขึ้นมาเลย)&lt;br /&gt;
อาจเป็นเพราะปัญหา Uninitialized constant ActiveSupport::Dependencies::Mutex (NameError) จากไฟล์&lt;br /&gt;
cafe_grader/judge/scripts/config/environment.rb วิธีแก้ก็เหมือนกันเลยคือใส่ require &amp;#039;thread&amp;#039;&lt;br /&gt;
&lt;br /&gt;
#########################################################################################&lt;br /&gt;
&lt;br /&gt;
สำหรับปัญหา error during grading อาจเกิดจากปัญหาว่า box ไม่สามารถ copy output ออกมาได้ วิธีแก้ที่นำมาบอกนั้น&lt;br /&gt;
ไม่แนะนำเป็นอย่างยิ่ง แต่แก้ปัญหาได้ คือเปลี่ยน parameter ของ box จาก box -a 2 เป็น box -a 9&lt;br /&gt;
ในไฟล์ cafe_grader/judge/scripts/std-script/run (บรรทัด run_command = &amp;quot;#{problem_home}.....&amp;quot;)&lt;br /&gt;
อย่างไรก็ตาม ไม่รับประกันผล/ปัญหาใดๆที่จะเกิดตามมาจากการแก้ด้วยวิธีนี้&lt;/div&gt;</summary>
