Dropping python <=3.9 support for next version of Frappe/ERPNext

[NCP]

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

bench get-app erpnext https://github.com/frappe/erpnext
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`

How to resolve issue @ankush.

[Douglas_muriuki]

Experiencing the same problem while installing Frappe and ERPNext version 13

Using Python 3.10

[ankush]

@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.

[Douglas_muriuki]

Resolved by installing python{version-string}-dev

[NCP]

Ohh great @ankush

I resolved the issue for develop branch by python{version-string}-dev

sudo apt install python3.10-dev

I was stuck for two days then after resolved.

Thank You!

[Kavitha]

@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

Thanks In Advance!

[charleyarnold]

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’

How to upgrade to python 3.10

Recently, Frappe updated its dependencies for version-14 to python > 3.10. If you’re on version-13, try to upgrade to python3.8 instead. Here’s what I did to upgrade to python3.10 under Ubuntu 20.04. Remember to take a backup of your server first! Install custom PPA, so Ubuntu knows where to find python3.10: sudo apt install software-properties-common -y sudo add-apt-repository ppa:deadsnakes/ppa Install required python packages: sudo apt install python3.10 pytho…

[charleyarnold]

Ok thank you, I have followed your suggesting to the tee, but am still getting the same error, I have even set python 3.10 on auto mode;

here are 2 choices for the alternative python (providing /usr/bin/python).

Selection Path Priority Status

• 0 /usr/bin/python3.10 2 auto mode
  1 /usr/bin/python3.10 2 manual mode
  2 /usr/bin/python3.8 1 manual mode

am not sure if I should also change the enviroment, please take note this is a fresh installation and am failing to bench init

[Pheakdey_Tes1]

This problem took me few days also and I fix it by follow this link

Upgrade Python to latest version (3.10) on Ubuntu Linux (cloudbytes.dev)

[charleyarnold]

Thank you this worked for me very well until I started hit a snag when now try to ran bench setup production (username) : I am getting an error associated with python3-apt, let me paste the error below

I have tried to follow other solutions on the net like

cd /usr/lib/python3/dist-packages

and pasting these two;

sudo ln -s apt_inst.cpython-38m-x86_64-linux-gnu.so apt_inst.so
sudo ln -s apt_pkg.cpython-38m-x86_64-linux-gnu.so apt_pkg.so

since am not sure what version 3.10 uses for these files i left them as for version 3.8

I also did the same on this route

/usr/local/lib/python3.10/dist-packages

Am still getting the same error not sure if you had success. Am using ubuntu 20.04LTS , am considering reinstalling the OS and try again

[smino]

Hi,

If you decide to start with a fresh OS , consider Ubuntu 22.04 LTS as it has python3.10 as default. That might make things easier.

[charleyarnold]

Thank you let try that will get back

[charleyarnold]

I have managed to get to work thank you for your assistance. This made me document each every step which am going to post, maybe it will help someone in similar situation

[jcagbay]

I think python 3.9 need to be supported since Debian and one of the RPM based distro Stream has python install defaults with this version. There are upgrade install using tarballs for pyhton version 3.10 but that is another story.

Hi, can you send the step by step instruction to install ERPNext version 14 (stable) on ubuntu 20.04 or 22.04?

[Douglas_muriuki]

You can consider checking this

[Guide] How to install ERPNext v14 on Linux Ubuntu (step-by-step instructions)

Hi guys! ERPNext v14 has just released and I know everyone wants to try it out quickly. Installing Frappe & ERPNext can be a daunting task, especially when try to install it manually but don’t worry! Just follow this simple step-by-step guide and you’ll sail through the installation process. This guide might look intimidating at first but trust me it is lengthy because it is detailed and explains each step one by one. Let’s start! Table of…

[blaiseAI]

I am getting started with Frappe Framework, But I am getting this error. Does anybody know how to fix it.

[Solufy]

Hi @blaiseAI,

If you installing version 14 then apply it.

bench init frappe-bench --frappe-path https://github.com/frappe/frappe --frappe-branch version-14 --python python3.10

[blaiseAI]

Thanks you, I will bookmark this manual option. I had tried using Docker and I think I prefer that way as I don’t run into dependency issues.
