“ rails new”命令出錯（使用rbenv）

Question

我已經安裝了rbenv，ruby和rails，但是創建新的rails項目的命令導致sqlite出現異常。

rails new first_app

Make sure that `gem install sqlite3 -v '1.3.6'` succeeds before bundling.

我試過安裝sqlite gem並重新哈希rbenv ，但是同樣的錯誤。 有人對如何解決此問題，確切的寶石名稱等有任何想法嗎？

Answer 1

我遇到了同樣的問題，並在ubuntu上安裝了sqlite軟件包：

apt-get install libsqlite3-dev

Answer 2

問題是您缺少編譯mysql適配器所需的頭文件。 該錯誤提示“嘗試'port install sqlite3 + universal'或'yum install sqlite-devel'並檢查您的共享庫搜索路徑（您的sqlite3共享庫所在的位置）”。 我會首先這樣做，因為這將確保您的計算機上具有正確的頭文件。 擁有它們之后，可能必須為編譯器指定文件的位置，“-with-sqlite3-include”指令可能會解決問題。

Answer 3

您的盒子上似乎沒有安裝sqlite 。 如果沒有底層，則不會安裝gem。

請執行以下操作：

• macosx： brew install sqlite
• 企業linux： sudo yum install libsqlite3-dev
• ubuntu： sudo apt-get install libsqlite3-dev
