stable diffusion 运行时报错： returned non-zero exit status 1.

1. 原因：python版本过低，使用3.10

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.10
python3.10 --version

1. python3.10 -m venv venv
   1. 报错：Error: Command '['stable-diffusion-webui/venv/bin/python3.10', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
2. 从新安装venv：

   1. sudo apt-get install python3.10-venv python3.10-dev
      python3.10 -m ensurepip --default-pip
      rm -rf venv  # 删除现有虚拟环境
      python3 -m venv venv
