windows 安装Linux子系统 Ubuntu 并配置python3

环境说明：

Windows 11 Ubuntu 20.04.6

安装步骤以及问题：

1、开启Windows Subsystem for Linux

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

2、开启虚拟机特性

dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

3、下载并安装WSL2更新包

4、将WSL2设置成默认

wsl --set-default-version 2

注：以上命令均以powershell的管理员命令执行

若未执行以上命令，直接安装Linux子系统，会出现如下报错：

5、打开Microsoft store 获取（我已经安装，所以是打开，未安装则显示获取）

6、打开软件

配置用户名和密码，到此，安装结束

7、配置国内安装源（加快系统包安装速度）

备份配置文件：sudo cp /etc/apt/sources.list /etc/apt/sources_bk.list

修改配置文件：vim /etc/apt/sources.list

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

将上述内容覆盖即可，

8、更新系统包列表
