Bench Start Error in Development - Error: No such commands watch serve worker schedule, frappe commands!?

Hi All,

I encountered an error after I run bench start.
My installation is switch from production to development, I strictly followed the steps on Github to switch from production to develop.
My installation is on AWS EC2 fresh instance.
The error code is as below:

Hopefully the masters can give me some advice as I want to build some application on frappe.
Cheers!

Hi Whats the development ram capacity of the server your trying

@Akkash,

It is 1GB. but I have 1GB Swap memory on:

frappe@ip-172-31-23-138:~/frappe-bench$ sudo swapon -s
[sudo] password for frappe:
Filename                                Type            Size    Used    Priority
/extraswap                              file            1048572 256     -2

Try this…

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

and then

bench start

I found just rerun ‘bench update’ to solve the missing frappe commands problem!?

I had the exact same problem: Error: No such command “worker”.

Solved it by just running bench set-default-site SITENAME

I had shut down and restarted the instance. Maybe that config gets reset in some way. bench start worked as normal after that.

Here’s another ‘Error: No such command’ case and fix just now:
