无法在Jupyter Notebook中访问Anaconda上已安装的软件包

我将Anaconda安装在外部驱动器inode/directory/0C707E95707E84EC上.我打开了Anaconda-Navigator，将r-aer安装在base(root)中.到目前为止，一切都很好.然后，我从inode/directory/0C707E95707E84EC启动Jupyter Notebook，无法访问aer库. 这一切都是从上周开始的.当我无法安装aer时，经过一番混乱，我终于结束了对Anaconda的更新，然后不得不删除并重新安装它.我要做的就是在Jupyter Notebook上访问aer.下图(最后一张图)显示library(raer)；我尝试了许多不同的命令版本，例如library("Raer")及其变体.

I installed Anaconda on an external drive inode/directory/0C707E95707E84EC. I opened Anaconda-Navigator to install r-aer in base(root). So far so good. Then I start Jupyter Notebook from inode/directory/0C707E95707E84EC and am unable to access the aer library. This all started last week. when I was unable to install aerand after a circus of affairs I finally ended up updating Anaconda and then having to delete and reinstall it. All I want to do is access aeron Jupyter Notebook. The image below (last image) shows library(raer); I have tried many different command versions, e.g. library("Raer")and variations thereof.

我知道Anaconda中安装了AER .这可能是路径问题吗?

I know that AER is installed in Anaconda . Could this be a path issue?
