rm -rf frappe-bench
This will delete the bench or if you would like to keep it, create another bench with the installer. Specify new directory name with -b flag. Since it is a dev server and you start the bench manually from the bench dir it shouldn’t matter.
Full command:
python installer.py -n 20 -d mariadb -b frappe-bench-2 -s dev2.localhost
cd frappe-bench-2
bench use dev2.localhost
Note: I used dev2.localhost to avoid confusion when having two benches.
Hope this helps
