مشكلة عند محاولة تشغيل Rails Server

Question

آسف إذا كان هذا سؤالًا سيئًا، فأنا أحاول إعداد Rails في البداية، لذلك لا أعرف حقًا ما أفعله.في البرنامج التعليمي الذي أتابعه، وصل الأمر إلى نقطة يُقال فيها تشغيل "خادم Rails"، ولكن هذا يؤدي إلى بعض النتائج غير المتوقعة. (انظر أدناه)

Macbookpro:First Cameron$ sudo rails server

=> Booting WEBrick
=> Rails 4.1.0 application starting in development on http:// 0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server

آسف إذا لم تكن هناك حاجة لذلك، ولكنني لست متأكدًا حقًا مما يجب فعله به.

Answer 1

ولا أعتقد أنك وحدك في هذا الخطأ.تأكد من تنسيق إصدارات الأحجار الكريمة الخاصة بك، ومن الأفضل تحديد إصدارات جواهر Rails & Ruby الخاصة بك لتجنب التعارضات المحتملة في الإصدار.

سيكون نشر ملف Gemfile الخاص بك مفيدًا، ولكن بدون رؤيته، أود أن أقترح تحديد إصدار Ruby الخاص بك في الجزء العلوي من ملف Gemfile الخاص بك مثل:

source 'https://rubygems.org'
ruby '2.0.0'

ثم حدد إصدار Rails الخاص بك.بينما لم أواجه أي مشاكل في تقديم ما يلي:

gem 'rails'

يمكن أن تكون أكثر أمانًا وتحدد إصدارًا مثل:

gem 'rails', '4.0.2'

ثم اركض: bundle install لتطبيقك.

Answer 2

إلقاء نظرة على البرنامج التعليمي التالي.أدرك أنه من أجل Windows ومع ذلك حلها جميع المشكلات الأولية التي كنت أقضيها مع أول تثبيتي الأول.

النقطة الرئيسية التي ساعدتني في تثبيتها تماما؛

قم بتشغيل gem update على تثبيت جديد للتأكد من أن كل شيء محدث
