更新了 Ubuntu 并重新安装了 R，现在如果我尝试在终端上运行 R，我会得到以下错误，我得到了问题所在
/usr/local/lib/R/bin/exec/R: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory
我尝试了一些线程仍然无法解决
Ubuntu 18.04 中的 libreadline.so.6 问题
$ which R
/usr/local/bin/R
$ R --version
/usr/local/lib/R/bin/exec/R: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory
$ dpkg -l "libreadline*"

答案1
为了获得更可重复的结果，我建议删除本地安装的 R
sudo rm /usr/local/bin/R
然后从官方存储库安装版本
sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install r-base-dev
然后通过运行来测试安装R --version。
