Same problem here with successful fix Bench update fails: /bin/sh: 1: ./env/bin/pip: not found - #7 by kdevloper
I tried it before i write here, i reached where i have to execute in bench folder ./env/bin/easy_install pip and it still gives me no such file or directory, now i am stuck
Perhaps you got something like this:
frappe@ubuntu:~/frappe-bench$ ./env/bin/pip install pip --upgrade

Nope, Thats what i get exactly
root@erp:/home/frappe/prod-bench# ./env/bin/pip install pip --upgrade
-bash: ./env/bin/pip: No such file or directory
I think something is missed up when i tried to migrate python env to return back to python2.7, as of now when i try to do
root@erp:/home/frappe/prod-bench# bench migrate-env python3.6

Yes same for me, so then first do this:
frappe@ubuntu:~/frappe-bench$ ./env/bin/easy_install pip
then this:
frappe@ubuntu:~/frappe-bench$ sudo ./env/bin/pip install pip --upgrade
same error
root@erp:/home/frappe/prod-bench# ./env/bin/easy_install pip
-bash: ./env/bin/easy_install: No such file or directory
ok sorry I can’t be of much help here, I have little sense of environments
no problem, just dont know what just happened here 
I reinstalled the server, and the same problem, i think there is something wrong i dont know what, started from scratch and still the same error
Was there any headway with this? I’ve got the same thing- ./env doesn’t seem to be there.
Something to be aware of: If you find you must run as root - or if any bench commands only run on sudo - that typically means and invites environment problems.
Best to leave super powers to those who know precisely what they are doing 
I understand that I was likely the root cause. In fact, I can almost guarantee that it is linked back to me running some sudo upgrade and sudo update commands on the root system rather than just going through bench.
That being said, I’m just trying to determine if this is something that can be fixed, or if I have to try to restore/rebuild from scratch. If one ‘oops’ (regardless of size) is enough to render the system doa and make all of the data iffy at best, it’s a bit of a concern as I move forward with full deployment (and heavy reliance).
Luckily, this was during my research and develop (on a production install) stage in preparation to move to my full-on production build, so it would only take a few hours to rebuild from scratch.
Nevermind. The page linked above actually does contain the solution- it’s just spread amongst the various comments about uninstalling/reinstalling mysql/mariadb, etc. Since this page was the most recent to come up when I searched for the ./env/bin/pip not found “root cause” error, I’ll sum up.
Basically I (and you, person who found this) screwed up by sudo updating from root rather than just running bench update. To fix-
From the frappe-bench directory:
bench setup env
./env/bin/pip install -e ./apps/frappe
./env/bin/pip install -e ./apps/erpnext
bench update
This got my system back up. I assume I can now proceed with standard bench update/migrate and/or normal operations. Will update this if further issues are encountered.
Okay. Follow up.
It actually looks like I didn’t break anything due to tossing around sudo root updates as previously speculated. Rather, this entire thing was caused by one simple thing it would seem.
WHAT HAPPENED TO ME:
After seeing a few mentions here and there about migrating to python3, I saw a few posts… somewhere?.. on here that mentioned it was performed with:
bench migrate-env **python_3.5/6_** <<<WRONG
Instead of:
bench migrate-env python3 <<<CORRECT
If you run that, with either “python3.6” or “python3.5”, it prepares for the update by backing up/archiving the python2.7 env (which I never quite figured out how to restore, but that’s probably just a noob mistake), then discovers that the folder, etc. doesn’t exist and errors out resulting in there not being any env mounted/present/whatever. So, if you go and look, and find the correct migrate command, it doesn’t work now and you end up screaming at your screen the 4hrs. Or more. But let’s go with 4 hrs.
So anyway. Yeah. Follow the latest and largest migrate threads (currently… this one?).
bench setup env solve the problem
