Error in installation command (42) and error in death timing

Hello guys ! great work but two issues:

for the installation command line in 42:
`python3 -m pip install psutil --user` and not `python3 -m pip install psutil -user`

And death timing doesn't work for me in the school.
However my printing is good:
`00000000001 3 is eating`
the logs:
```
