mac安装rpy2问题

这个问题就是有点奇怪，我在base环境中安装rpy2没有问题，但是我在QUEST环境中安装我就出现了问题，很奇怪的一个东西

错误如下

(QUEST) yxk@bogon ~ % pip install rpy2

问题解决，这个问题出在R的版本安装上，我之前默认安装的R都是使用就的intel，实际上是有新的安装包，

所以这里涉及到怎么删除R的问题
https://www.imymac.com/powermymac/uninstall-r-mac.html

最重要的代码

sudo rm -rf /Library/Frameworks/R.framework

其余的部分rstudio和R可以通过应用程序直接删除
