運行rails服務器時找不到gem'rails（= 4.2.5）x86-mingw32'

我正在嘗試學習Ruby on Rails。目前正在嘗試Rails框架。我已經安裝了它。在MyBlog文件夾中創建新的項目，但是當我嘗試運行：運行rails服務器時找不到gem'rails（= 4.2.5）x86-mingw32'

rails server

我回來了一個錯誤：

Could not find gem 'rails (= 4.2.5) x86-mingw32' in any of the gem sources listed in your Gemfile or available on this machine. Run `bundle install` to install missing gems.

我已經安裝了捆綁的建議。安裝它也很少出現問題，但我在互聯網上發現了一個靈魂。

軟件包之前安裝我正在另一個錯誤說，它不能找到寶石「sqlite3的」

是否有人有類似的問題？你能幫我解決嗎？

更新：我的Gemfile的

內容是：

你有一個問題，但建議的解決方案解決了這個問題。大。但你之前還有另一個問題？你還擁有它嗎？我無法跟隨。你真正的問題是什麼？你現在面臨什麼問題？ – spickermann

@spickermann當我運行'rails server'命令時，問題不在於創建rails gem。 –

你能發佈你的寶石文件和軟件包安裝錯誤嗎？ – SaravanaKumAr

嘗試安裝以下軟件包成功捆綁安裝

sudo apt-get install build-essential 
sudo apt-get install libgmp3-dev

這些軟件包用於Linux環境。找到其他環境的替代方案。讓我知道你是否有任何錯誤。

我試過用gem install build-essentials ...但我想這不適用於Windows的命令，它適合您爲Unix提供的命令。我收到了： C：\ Users \ n.mosorinski \ Rails \ apps \ MyBlog> gem install build-essential 錯誤：在任何存儲庫中找不到有效的gem'build-essential'（> = 0）錯誤：可能的替代方案：knife-essentials，build_eval，essentials，spree_e ssentials –

我已經提到在答案本身 – SaravanaKumAr

你可以檢查這一個http://stackoverflow.com/questions/33084811/error-in-installing-json -gem換紅寶石在窗口 – SaravanaKumAr

打開文件Gemfile.lock的，找到並刪除「x64的mingw32的」然後運行命令： -

$捆綁安裝
