How to install frappe-bench compatible with erpnext 13?

As my VPS is powered by Ubuntu 20.04.4 LTS I want to install ERPNext 13. For this I want to install Frapper-Bench which is compatible with it.

How can I do this?

If I use the command sudo python3.8 -m pip install frappe-bench then it installs version 5.14.2.

And the command bench init --frappe-branch=version-13 --python=python3.8 frappe-bench fails with a long log of errors. Here is the output.

frappe@erp:~$ bench init --frappe-branch=version-13 --python=python3.8 frappe-bench

Do you want to rollback these changes? [y/N]:

Regards,

I managed to solve the problem.

I used the following command:

export LC_ALL=C.UTF-8

After this command bench init command worked!!
