我正在尝试使用rcdd安装一个名为conda build的R软件包，C编译器有问题。请注意，此问题看起来与
Conda build R package fails at C compiler issue on MacOS Mojave但是，由于（i）该问题仍未得到解答，并且（ii）这与其他软件包有关，我认为这不是重复的问题。
我正在使用conda 4.6.8的MacOS Mojave。在具有r-base和r-essentials的新conda环境中
安装，我尝试
conda install conda-build
conda skeleton cran --recursive rcdd
conda build r-rcdd
并出现以下错误
* installing *source* package ‘rcdd’ ...
** package ‘rcdd’ successfully unpacked and MD5 sums checked
checking for gcc... x86_64-apple-darwin13.4.0-clang
checking whether the C compiler works... no
configure: error: in `/Users/pjethwa/miniconda3/envs/r_env/conda-bld/r-rcdd_1553173041138/work':
configure: error: C compiler cannot create executables
See `config.log' for more details
ERROR: configuration failed for package ‘rcdd’
config.log文件包含相同的错误消息。当我尝试直接从R进行安装时（即使用install.packages('rcdd')），也会出现相同的错误。我 am 能够使用conda未安装的R版本安装此软件包。该解决方案并不令人满意，因为我想使用rpy2来连接python和R，这似乎要求conda安装R（例如，参见Getting Segmentation fault Core dumped error while importing robjects from rpy2）
