嘗試在安裝了Xcode（4.3.2）的OS X 10.7上安裝Passenger時出現錯誤：“您必須先安裝開發工具。”

Question

我試圖在安裝了Xcode（4.3.2）的OS X 10.7上安裝Passenger，這給了我錯誤：“您必須先安裝開發工具。”

這對我來說毫無意義，為什么它沒有找到適當的要求？ 我已經從Apple商店安裝了Xcode。

是否有所需的實際需求列表，而不是此通用消息？ 還是有人知道有什么解決方法可以幫助我在OSX Lion上與乘客同行？ 謝謝！

Answer 1

您可能需要安裝Xcode命令行工具

過去，這是Xcode安裝包中的可選項。 蘋果現在將它們分開（無論出於何種原因）

Answer 2

在XCode 4.3.2中，可以從XCode的“首選項”下的“下載”中安裝命令行開發人員工具。
