首次在Mac上安裝RStudio。 為什么我不能安裝任何軟件包？

Question

在Windows PC上工作多年后，我已經在Mac上成功安裝了RStudio。 不用說，軟件包安裝是我的下一步，但是每當我嘗試安裝軟件包時，都會返回錯誤。 當我嘗試安裝軟件包依賴項時發生錯誤...為了簡化起見，在此示例中，我將使用“ tibble”軟件包。

原諒我的新手編碼性質，我仍然每天學習。

我嘗試安裝不同的程序包（這些程序包全部來自CRAN），每次都出現相同的結果。

編輯：分別輸入“ no”，“ yes”將安裝軟件包。 有人知道為什么我仍然收到此輸出嗎？ 不必一次安裝一個軟件包，那就太好了。 謝謝！

> install.packages("tibble")
> y
> y

我希望安裝成功，但是實際輸出如下：

> install.packages("tibble")
also installing the dependencies ‘utf8’, ‘fansi’, ‘pillar’, ‘rlang’


  There are binary versions available but the source versions are later:
       binary source needs_compilation
utf8    1.1.3  1.1.4              TRUE
pillar  1.0.1  1.3.1             FALSE
rlang   0.1.6  0.3.4              TRUE
tibble  1.3.4  2.1.1              TRUE

Do you want to install from sources the packages which need compilation?
y/n: y
Package which is only available in source form, and may need compilation of
  C/C++/Fortran: ‘fansi’
Do you want to attempt to install these from sources?
y/n: y
installing the source packages ‘utf8’, ‘fansi’, ‘pillar’, ‘rlang’, ‘tibble’

錯誤消息告訴您缺少命令行工具。 它們提供了從源代碼編譯軟件包所需的軟件（例如C和C ++編譯器）。

您可以按照此處所述使用xcode-select --install來安裝它們，或者如注釋中所述，在提示您從源代碼進行編譯時選擇“否”。
