Error when adding new Frappe site

I am new to setting up Frappe.

I am using the command: bench new-site testsite.local

When I add a new site, I am getting the following error:
pymysql.err.OperationalError: (1054, “Unknown column ‘gcalendar_sync_id’ in ‘field list’”)

Please get in-depth, on which os you are trying and which step you are following for Erpnext Setup?

I am facing the same issue.

OS: MacOS Mojave
Step: bench new-site --force

I have tried this and and success. Previous step is not include.

Login as the newly created bench user.

sudo su - bench

Clone the Bench repository in /opt/bench.

cd /opt/bench
git clone bench-repo

Install Bench using pip.

sudo pip install -e bench-repo

Once Bench is installed, proceed further to install ERPNext using Bench.

Install ERPNext using Bench

Initialize a bench directory with frappe framework installed. To keep everything tidy, we will work under the /opt/bench directory. Bench will also setup regular backups and auto updates once a day.

cd /opt/bench
bench init erpnext && cd erpnext

Create a new Frappe site.

bench new-site site1.local
