当install.packages在最新的R(3.4)和RStudio 1.0.143中运行时,我收到以下警告
Warning in install.packages :
cannot open URL 'https://cran.rstudio.com/bin/macosx/el-capitan/contrib/3.4/PACKAGES.rds': HTTP status was '404 Not Found'
无论我选择哪个软件包,都会出现这种情况,但这似乎不会影响软件包安装.我尝试清除我的~/.rstudio-desktop,/Library/Frameworks/R.framework/Versions/3.4/Resources/library并重新安装R,这个警告仍然存在.晚上更换CRAN镜子似乎没有效果,因为出现了类似的警告.以下是我的会话信息.
