Successfully installed but command not found

[ReinforceZwei]

I use pip install webssh and successfully installed the app.
But when I try to launch it with wssh, it said -bash: wssh: command not found
I am running Debian 9 on Raspberry Pi
Using Python 2.7.13
Here are the installation logs:

I had to run pip install wssh after that.

I also noticed that if I just ran pip install wssh, I would get an error saying tornado.web not found. Which was remedied by running pip install webssh.

Debian has more strict rules for granting permissions.
Do you install webssh using virtualenv?
If not, try to install it within a virtualenv.

@larryathey installing wssh didn't solve my problem.
@huashengdun I can use wssh command now after installed webssh inside a virtual env. Thank you very much!
