r - Conda 构建 R 包在 MacOS Mojave 上的 C 编译器问题上失败

Question

我正在尝试使用 conda 安装一个名为 treatSens 的 R 包，以便在 Jupyter notebook 中使用它。我执行的命令:

conda 安装 conda-build
conda 骨架 cran treatSens
conda 构建 r-treatsens
conda install -c 本地 r-treatsens

我得到了关于 C 编译器的错误

* installing *source* package ‘dbarts’ ...

这似乎是使用特定版本的 Apple C 编译器构建 Conda 的问题。我的猜测是我需要为 conda build 定制 C 编译器。所以我的问题变成了

1. 我需要什么正确的 gcc 版本。
2. 如何为 conda build设置它。

Answer 1

作为一种快速而肮脏的解决方法(来自 comment)，我能够在 RStudio 中使用以下代码在 R 中安装包(在 conda env 中打开)

Sys.setenv(CONDA_BUILD_SYSROOT="/")

现在，您可以通过 RStudio 控制台安装任何 R 包，例如

install.packages("tidyverse")

希望这对您有所帮助。
