我正在尝试使用conda安装一个名为TreatSens的R软件包，以在Jupyter笔记本中使用它。我执行的命令：
conda install conda-build
conda skeleton cran treatSens
conda build r-treatsens
conda install -c local r-treatsens
我得到了有关C编译器的错误

看来，使用特定版本的Apple C编译器进行Conda编译存在问题。我的猜测是我需要为conda构建自定义C编译器。所以我的问题变成了

作为一种快速而又肮脏的解决方法（来自此comment），我能够使用RStudio中的以下代码（在conda env中打开）在R中安装软件包
Sys.setenv(CONDA_BUILD_SYSROOT="/")
现在，您可以通过RStudio控制台安装任何R软件包，例如
install.packages("tidyverse")
希望这会有所帮助。

要使MacOS Mojave正常构建，必须执行几项操作。由于对我来说很神秘的原因，Anaconda的人们not keen使之顺畅，这对于使用深奥R包的我们这些人来说尤其令人发疯。我将写出截至2019-04-20的最新信息：
1。安装Xcode（v10.2.1）
2。在开放源代码的地方安装标题通常会期望找到它们。在命令行中：
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
3。安装命令行工具
Command_Line_Tools_macOS_10.14_for_Xcode_10.2.1 xcode-select --install也会这样做。如果运行该命令，您应该会看到消息xcode-select: error: command line tools are already installed, use "Software Update" to install updates
4。下载旧版MacOS SDK文件的副本。例如，来自here
5。创建目录/opt
sudo mkdir /opt
6。将SDK文件复制到此处
sudo cp -r ~/Downloads/MacOSX10.9.sdk /opt/
sudo chmod -R a+rX /opt
7。创建一个conda_build_config.yaml文件，Conda-build和相关软件将引用该文件。它应包含以下内容
macos_min_version: - 10.9 macos_machine: - x86_64-apple-darwin13.4.0 MACOSX_DEPLOYMENT_TARGET: - 10.9 CONDA_BUILD_SYSROOT: # [osx] - /opt/MacOSX10.9.sdk # [osx]
在终端中，您可以执行以下操作：
mkdir ~/.conda || echo 'Dir already present'
cat "macos_min_version:" >> ~/.conda/conda_build_config.yaml
cat " - 10.9" >> ~/.conda/conda_build_config.yaml
cat "macos_machine:" >> ~/.conda/conda_build_config.yaml
cat " - x86_64-apple-darwin13.4.0" >> ~/.conda/conda_build_config.yaml
cat "MACOSX_DEPLOYMENT_TARGET:" >> ~/.conda/conda_build_config.yaml
cat " - 10.9" >> ~/.conda/conda_build_config.yaml
cat "CONDA_BUILD_SYSROOT:" >> ~/.conda/conda_build_config.yaml
cat " - /opt/MacOSX10.9.sdk" >> ~/.conda/conda_build_config.yaml
8。通过您的.condarc告诉Conda您的YAML文件。它应该包含以下行：
conda_build: config_file: ~/.conda/conda_build_config.yaml
可以使用
完成cat "conda_build:" >> ~/.condarc
cat " config_file: ~/.conda/conda_build_config.yaml" >> ~/.condarc
