@Mark80-lang I'm sorry for delay, I am trying to help a lot of people at the same time,

For me, install.packages("tidyverse") works,

could you try this?

pkg install which

which which

which which should show this, not /system/bin/sh:

~ $ which which
/data/data/com.termux/files/usr/bin/which
~ $

also please show the result of echo $PATH
