When exactly is version 14 of ERPNext going to be released? Are there any specific dates.
I am asking this because I am going to start work on a project in a few days. If version 14 is around the corner then I think it would be prudent to wait for this new release.
As a rule of thumb, I would suggest you don’t hold your breathe on new release being stable in the first few months at least. Version 13 spent nearly a year in beta and still had bugs on full release so it’s best you start your development in v13.
I want to add some info and context, for future readers. With Python 3.10 as a firm Frappe v14 requirement, you may need to perform additional installation work, depending on your Linux distribution.
Ubuntu: The latest Ubuntu LTS 22.04 (released 21 April 2022) ships with Python 3.10.
Debian: The current LTS, Debian 11 “Bullseye”, only has Python 3.9.
(Debian 12 has no official release date. Best guess is middle of year 2023.)
CentOS 8 : I’m unfamiliar with Red Hat distributions. I’ve read that they don’t actually ship with Python. But using their package installer, I “think” it would install Python 3.6?
So.
If you’re -not- running Frappe/ERPNext with Docker… and you’re -not- running Ubuntu 22.04… then be prepared to install Python 3.10 manually.
This may (or may not) be a challenge for you, depending on your comfort-level with Linux and Python.
Finally, for Ubuntu and Debian users, this means you’re going to have two(2) different Python versions co-existing on your host. So please be careful with that, and give thought and consideration to your Python Virtual Environments.
I have successful installations using AlmaLinux 8 (having Python 3.6.8) - and for me this is easier than using Ubuntu
I am going to try AlmaLinux 9 (Python 3.9.10) in the next few days.
For version 12 and 13, what is expected to break, if any, when using Python 3.9 or 3.10?

If you prefer to avoid building psycopg2 from source, please install the PyPI

I have also faced the same issue in develop branch when installing the erpnext app.
Frappe installed successfully and it’s worked fine but when I get the erpnext app then

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

@NCP that appears to be due to missing development libraries.
If you’re running python you need to install python{version-string}-dev package too, that’s complete python distribution; by default ubuntu might not be installing development packages.
@ankush I already have Python 3.8.10 . If I install sudo apt install python3.10-dev this any problem raised in future when gaving bench start. Please let me know
I am also having the same challenge, I installed python3.10 manually and I now have both versions 3.8.10 and 3.10 and also ran also sudo apt install python3.10-dev and installed the packages but am still getting >> ERROR: Package ‘frappe’ requires a different Python: 3.8.10 not in ‘>=3.10’
