Question: I made multiple observations of my plants (one per week) and divided the plants into 2 groups (with and without treatment). My data structure looks like this:

```
Treatment   Leaf Area 1 Leaf Area 2 Leaf Area 3 Leaf Area 4 Leaf Area 5
none        2.411545455 13.02745987         
yes         1.199545455 0.412511147         
none        2.448363636 28.56727482 51.49511341 49.38664803 15.63761378
yes         2.797454545 23.49791914 31.97397924 39.60835617 8.544331072

```

I want to create a line chart similar to the following. Can anyone please help me? I don't really know where to start looking.

Answer: 
I think this command will help you to resolve this issue

```
$ export ANSIBLE_LIBRARY=/

```

Ansible will search for modules at the path specified.
`unset ANSIBLE_LIBRARY`

`ANSIBLE_LIBRARY` was set to a bad path which was causing this error.
