在 Mac 上找不到已安装的 gfortran 软件包

Question

我运行的是 MacOS Ventura 13.6.7。我想使用RStudio安装nlme R包，这需要编译。当我尝试安装它时，出现以下错误：

installing the source package ‘nlme’

我已从此链接下载并安装了 gfortran：https://mac.r-project.org/tools/gfortran-12.2-universal.pkg.

安装在这里：/opt/gfortran/bin/gfortran

但是，我仍然收到错误。

我认为你应该从

here

安装 gfortran；这是来自 R for MacOS X 开发工具和库 页面。此版本将安装到 /usr/local/gfortran 中，并将最大限度地提高

gfortran

位于正确位置并被 R 编译工具找到的机会。

（对我来说，为什么需要从源代码编译并不明显；https://cran.r-project.org/package=nlme 为大多数 MacOS 平台提供二进制文件。）
