在我的应用程序中,我必须提供"另存为图像"按钮.我想将我在网页上呈现的HTML保存为JavaScript中的图像.它是一个webapp,将用于桌面/平板电脑/手机的浏览器.如何将渲染的HTML保存为图像？

我已经安装了Vagrant,一旦我从终端进入我的项目文件夹,我就会激活以下命令:

1. vagrant box add hashicorp/precise32 http://files.vagrantup.com/precise32.box

输出:

[vagrant] Downloading with Vagrant::Downloaders::HTTP... 
[vagrant] Downloading box: files.vagrantup.com/precise32.box 
[vagrant] Downloading box: hashicorp-files.vagrantup.com/precise32.box 
[vagrant] Extracting box... 
[vagrant] Verifying box... 
[vagrant] Cleaning up downloaded box...

2. vagrant init hashicorp/precise32

输出: A Vagrantfile has been placed in this directory

3. vagrant up

我收到一条错误消息:

The box 'hashicorp/precise32' could not be found
