When I run the following command

```
qc.draw(output='mpl')

```

for my circuit qc, I get this error:

```
ImportError: The class MatplotlibDrawer needs pylatexenc

```

How do I address this issue? Below an image of my problem

**Update** ------   

Installation steps on Google Colaboratoy:   

`!pip install pylatexenc ?`.

The installation attempt (was successful and the installed `pylatexenc` has version `2.7`.)
