Seems like pip in not setup correctly in ./env/bin
(or are you running from the frappe-bench folder?)
I have the same problem.
It seems, that the update mechanism is very shaky. I am running bench 3, ERPNext v7.
Now my system is broken and i dont know how to bring it back to live.
It is not a production system, but looking at production scenarios the update mechanism must be bulletproof… 
UPDATE:
I found a hint from vjFaLk:
sudo apt-get install libffi-dev
This handles the error and interruption of the bench update.
After installing this missing package the update went successfully and the ERPNext started also without any problems.
Problem solved.
@Idat-Consulting, I faced a similar issue. This is how I fixed it:
- cd to frappe-bench folder and run ./env/bin/pip install -q -e ./apps/frappe
- run ./env/bin/pip install -q -e ./apps/
- Add an entry for your app name to /sites/apps.txt
hey @stevenyaga thanks its work for me by run this command on frappe-bench folder
./env/bin/pip install -q -e ./apps/
run ./env/bin/pip install -q -e ./apps/
Add an entry for your app name to /sites/apps.txt
second and third command did`t work for me. got error
