無法在 R-Studio 中安裝任何軟件包

Question

我在macos Yosemite Version 10.10.5版本 10.10.5 上運行r-studio version 1.1.463 。 我的筆記本電腦是 2015 年初的。每當我嘗試在 R-Studio 中安裝任何軟件包時，它都會給我這個錯誤消息：

抱歉，我是一個完整的 n00b，但我不確定這是否意味着軟件包確實被下載了。 如果有，我在哪里可以找到它們，我需要做什么才能將它們安裝在 R-Studio 中？ 我沒有 C 編譯器，也不確定是否需要。

提前非常感謝。

• 請注意錯誤：“在 '/Applications/Xcode.app' 中未找到開發人員工具，請求安裝。”
• Note this is also stated from R studio's dependencies page: "The core software development utilities required for R package development can be obtained by installing the Command Line Tools for XCode. You can do this in one of two ways." 資源

您需要安裝命令行開發人員工具。 啟動您的終端並執行以下操作：

xcode-select --install

然后重試安裝。
