Hi NIKHIL;

Thank you very much for answering me but here is what i got for each one:

1- Requirement already satisfied: decorator in /usr/local/lib/python3.4/dist-packages (4.0.10)

2- Requirement already satisfied: decorator in /usr/local/lib/python3.4/dist-packages (4.0.10)

3-python3-decorator is already the newest version.

0 mis à jour, 0 nouvellement installés, 0 à enlever et 584 non mis à jour.

which means that the package is well installed.

So what would be the problem my friend.

Need Help please.

Best regards.

Hi Vale Trood,

Just try these, definitely one of them will work for you.

sudo python3 -m pip install decorator

or

sudo pip3 install decorator

or

sudo apt-get install python3-decorator

Regards,

Nikhilkrishnan
