尝试在 Ubuntu 14.04 LTS 32 位上安装插入符号包时，我收到以下警告

The downloaded source packages are in

‘/tmp/RtmpnrWGAe/downloaded_packages’



 Warning messages:
1: In install.packages("caret") :
  installation of package ‘nloptr’ had non-zero exit status
2: In install.packages("caret") :
  installation of package ‘lme4’ had non-zero exit status
3: In install.packages("caret") :
  installation of package ‘pbkrtest’ had non-zero exit status
4: In install.packages("caret") :
  installation of package ‘BradleyTerry2’ had non-zero exit status
5: In install.packages("caret") :
  installation of package ‘car’ had non-zero exit status
6: In install.packages("caret") :
  installation of package ‘caret’ had non-zero exit status

最佳答案

在安装“caret”包之前，您需要安装所有依赖项。

install.packages(c('lme4', 'pbkrtest', 'BradleyTerry2', 'car', 'caret'))

上面的代码应该可以解决这个问题。

或者你可以使用:

install.packages('caret', dependencies = TRUE)

然后，您可以尝试使用上述命令安装“nloptr”包。
