Hello,
Everything went well. Got bench also installed. I did cd to frappe-bench folder ( $cd frappe-bench/ ).
And when i run $ bench start, i am getting this error:
Traceback (most recent call last):
File “/home/vinod/.local/bin/bench”, line 11, in
load_entry_point(‘frappe-bench’, ‘console_scripts’, ‘bench’)()
File “/home/vinod/bench-repo/bench/cli.py”, line 45, in cli
if sys.argv[1] in get_frappe_commands() + [“–site”, “–verbose”, “–force”, “–profile”]:
TypeError: unsupported operand type(s) for +: ‘NoneType’ and ‘list’

Help me out please…

In production you don’t have to do bench start It starts with server. This is needed only for develop branch. Your site should be online.

Hello,
when i start my bench i am getting this error shown below:

~/erpnext/frappe-bench$ bench start
WARN: bench is installed in editable mode!

This is not the recommended mode of installation for production. Instead, install the package from PyPI with: pip install frappe-bench
