Can't preview in the cygwin enviroment

[vertexi]

Describe the bug Can't preview markdown in the windows cygwin enviroment.

To Reproduce Steps to reproduce the behavior:

1. use vundle install the plugin
2. call mkdp#util#install()
3. just preview any markdown file in vim by MarkdownPreview

Expected behavior Automatically open default browser and preview the markdown file.

Screenshots Just output the No matching autocommands message when I run MarkdownPreview

Desktop (please complete the following information):

• OS: Windows 10 cygwin enviroment
• node v15.13.0

And this is the vim log when MarkdownPreview crashs. Log:

[vim-node-rpc] rpc error: node:internal/modules/cjs/loader:927
[vim-node-rpc] rpc error:   throw err;
[vim-node-rpc] rpc error:   ^

[vim-node-rpc] rpc error:   code: 'MODULE_NOT_FOUND',
[vim-node-rpc] rpc error:   requireStack: []
[vim-node-rpc] rpc error: }

I guess it's the 'C:\cygdrive\c\Users\Apoptosis.vim\bundle\markdown-preview.nvim\app\index.js' issue.
