如何修复pyxel中的“无法在'系统'中初始化SDL”

Question

I was tried to excecute tutorial code include pyxel import, but there was some error "pyxel error: failed to initialize SDL in 'System'" Should I install some additional packages?

I'm using WSL (ubuntu18.04) and python 3.7.4 . I already installed :

• libsdl2-dev
• libsdl2-image-dev
• libssl-dev
• zlib1g-dev
• libbz2-dev
• libreadline-dev
• libsqlite3-dev
• wget
• curl
• llvm
• libncurses5-dev
• libncursesw5-dev
• xz-utils
• tk-dev

import pyxel

class app:
    def __init__(self):

Answer 1

It seems to be that Microsoft does not support graphical programs on WSL. This article describes how to go about using an X server on Windows to accomplish using GUI applications from WSL.

You should be able to install Xming (or another X server program of choice) on Windows, and then from inside Ubuntu use the following commands to install some X applications and test to make sure it works properly.

sudo apt-get install x11-apps

export DISPLAY=:0

xeyes

You should see the xeyes program pop up in a new window.

Now, all you should have to do is export your display before running the pyxel tutorial code.
