补充：卸载重装命令：
wsl --list #查看名称
wsl --unregister Ubuntu #卸载wsl
第一步：打开cmd，以管理员方式运行 wsl --install
第二步：安装完成后重启电脑，首次重启，会要求设置用户名和密码
第三步：更新apt，安装vim
apt-get update # 更新apt
sudo apt-get install vim # 安装vim(如果有vim可不执行此步骤)
第四步：换源（一般会换成国内源，可省略）
cd /ect/apt
# 先备份源文件
sudo cp sources.list sources.list.bak
# 修改源
vim /etc/apt/sources.list
# 清空文件内容，然后选择一个源复制进去，选一个就可以了，我用的是阿里云的（源看第四步）
最后保存退出即可(:wq)
第五步：源镜像

第五步：更新源列表
sudo apt-get update #更新源
sudo apt-get upgrade #更新软件
补充说明：如果换源之后报错如下，可使用以下方法解决：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32 #最后一串数字改成报错中显示的数字，我这里是3B4FE6ACC0B21F32
进行文件拷贝（windows系统默认在/mnt下）
- 从windows向子系统（linux拷贝）
使用wsl子系统窗口
sudo -i # 进入管理员模式
cd /mnt/c/Users/jenso/Desktop # 进入windows目录桌面
cp xxx.zip /etc/static/ # 拷贝桌面的文件到wsl子系统/etc/static目录下
- 从linux子系统向windows系统拷贝
使用wsl子系统窗口
cp /aa.nginx /mnt/d # 表示拷贝文件到d盘
