無法在新安裝的Rails上創建新應用程序

我試圖在全新的Rails安裝上創建一個新應用程序，它給了我一個'權限被拒絕'，然後很多之前的其他東西根本不工作。無法在新安裝的Rails上創建新應用程序

我試圖尋找答案，但它似乎並沒有很容易找到答案。這是我的終端是什麼樣子：

我不知道我需要什麼，或者我需要做的。我應該提到我在1歲的Macbook Pro上運行OSX Lion（10.7）。

對於您嘗試創建Rails應用程序的目錄，您沒有寫權限。確保該目錄屬於您的用戶chown，並確保您擁有對該目錄的寫入權限chmod。

看起來你正試圖在根目錄下創建一個rails應用程序，當你應該在你的「home」目錄下。在OS X中是/ Users/Zach。這樣做：

cd ~/ 
mkdir rails_projects 
cd rails_projects 
rails new first_app

謝謝，湯姆！這工作！我想知道爲什麼這個教程讓我在根中創建它。由於我是這臺計算機上唯一的用戶/管理員，所以我始終沒有想到，在根目錄下創建的文件夾將無法寫入訪問權限。 – 2012-03-15 06:04:10

是的，那將是一個奇怪的疏忽。你確定教程中提到'mkdir/rails_projects'而不是'mkdir rails_projects'嗎？第一次嘗試在根目錄中創建，第二次嘗試與當前路徑相關，這通常是您的主目錄。 – 2012-03-15 20:08:16
