WebVM是一款基于WebAssembly技术的浏览器虚拟机，可直接在浏览器中运行完整的Linux环境，无需服务器支持
源码：https://github.com/leaningtech/webvm/
github部署
安装介绍：
动手实践：
打开网站：https://github.com/leaningtech/webvm
fork到自己的github账户：
直接点setting：
在setting页面，点击pages：
在Pages展开的右边页面，打开Build and deployment下面的GitHub ACtions，选Deploy from a branch：
可以看到把main映射到根目录了：
然后点Action：
出现Workflows页面，点绿色的大按钮：
出现Actions页面，点左侧的Deploy按钮：
点右侧的Run workflow,然后点绿色按钮：Run workflow
后面就是慢慢等待发布成功：
但是不知道为何，我这边发布是失败的。
本地部署
下载源码
git clone https://github.com/leaningtech/webvm.git cd webvm下载Debian mini 镜像
wget "https://github.com/leaningtech/webvm/releases/download/ext2_image/debian_mini_20230519_5022088024.ext2"修改配置文件
Edit `config_public_terminal.js` to reference your local disk image:
Replace:
"wss://disks.webvm.io/debian_large_20230522_5044875331.ext2"With:
"/disk-images/debian_mini_20230519_5022088024.ext2"(Use an absolute or relative URL pointing to the disk image location.)
Replace
"cloud"with the correct disk image type:"bytes"
最终修改成这样
// The root filesystem location // export const diskImageUrl = "wss://disks.webvm.io/debian_large_20230522_5044875331_2.ext2"; export const diskImageUrl = "debian_large_20230522_5044875331_2.ext2"; // The root filesystem backend type // export const diskImageType = "cloud"; export const diskImageType = "bytes";build
npm install npm run build实战中我是使用了pnpm
pnpm install pnpm run buildbuild完成提示：
[vite-plugin-static-copy] Copied 6 items. ✓ built in 32.50s Run npm run preview to preview your production build locally. > Using @sveltejs/adapter-static Wrote site to "build" ✔ done配置nginx
mkdir disk-images mv debian_mini_20230519_5022088024.ext2 disk-images/修改nginx.conf文件，加入：
location /disk-images/ { root .; autoindex on; } 启动nginx
sudo nginx -p . -c nginx.conf出来页面了
尽管只是个黑黑的控制台，也很棒了！
不过后面有报错，没搞定。
调试
pnpm run build报错

发现是注释用错了，不应该用#，要用//
// The root filesystem location // export const diskImageUrl = "wss://disks.webvm.io/debian_large_20230522_5044875331_2.ext2"; export const diskImageUrl = "debian_large_20230522_5044875331_2.ext2"; // The root filesystem backend type // export const diskImageType = "cloud"; export const diskImageType = "bytes";build完成
这段代码应该放到nginx的哪里？
location /disk-images/ { root .; autoindex on; }放到主文件的location / 后面或前面
webvm启动报错

CheerpX internal error message is:

不知道为啥啊！是不是国内网络的锅啊？
