Why does bash report that it can’t find the module command?

The error you see is:

bash: module: command not found"

The module is a shell function that is declared in /etc/bashrc.
It is always a good idea for /etc/bashrc to be sourced immediately in you ~/.bashrc

Edit your .bashrc file so that the first thing it does is o execute the system
bashrc file, i.e. your .bashrc file should start with the following lines:

# Source the global bashrc
 if [ -f /etc/bashrc ]; then
 . /etc/bashrc
