Question

我在安装R软件包devtools时遇到了这个问题。我的R工作室在Anaconda，它是最新版本。代码是这样的：

install.packages("devtools")

我得到的答复如下：

also installing the dependency ‘git2r’

为了解决这个问题，我尝试了以下但没有改变：

检查Xcode和命令行工具，并确保命令行工具是最新版本。
更新所有anaconda包。
更新homebrew
更新gcc
重启我的笔记本电脑。

现在我已在终端中使用此代码安装此软件包：

conda install -c r r-devtools

当我在R控制台中输入install.packages("devtools")时，似乎没有任何错误，我看到反馈如下：

但我不确定我是否还有C编译器问题。如果是这样，我仍然希望解决这个问题，以便将来方便。而且，我不知道为什么我首先要解决这个问题。

macos：configure：错误：安装R pachage时，C编译器无法创建可执行文件
