AttributeError: 'str' object has no attribute 'removeprefix'

[ebrahimraeyat]

Hi @lcpt . I compiled xc and run verification tests. It gives me a lot of error due to 'str' object has no attribute 'removeprefix' or 'removesuffix'. It seems it's introduce in python version 3.9+

To Reproduce Run this test: Traceback (most recent call last):

According to this, removeprefix was added to string class in Python 3.9. The current Python version in Ubuntu 22.04 is 3.10.12. What version of Python are you running?

[ebrahimraeyat]

yes, I use python 3.8.10

root@DESKTOP-7AJHP3M:/home/ebrahim/xc_soleh# python
Python 3.8.10 (default, Nov 14 2022, 12:59:47)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

I will update my ubuntu or python. Thanks.

I updated my ubuntu system and python. But can't compile correctly:

I also run this command to update required packages:

sudo bash packages_install_ubuntu_focal_fossa.sh

Hi, @ebrahimraeyat.

This is weird. The libraries in the /usr/lib/86_64-linux-gnu directory make part of the OS and, for example, librt.so belongs to the libc6 package which is needed to compile and link programs which use the standard C library (and XC libraries uses it, of course). I think something went wrong during the installation of the required packages.

Anyway, this has nothing to do with the original issue, so I will close it. Open another one if you need to.

Thanks, you are right.
