Deploy uses child_process to run your deploy command. It looks like the UNKNOWN errors occur either from permissions issues (this stackoverflow question) or from how Windows doesn't support shebangs to directly run files (https://github.com/babel/babili/issues/108#issuecomment-242938483).

What is the admin.deployCommand of your _config.yml? Try running the command directly in the terminal. Does it deploy correctly?

[xbotao]

Running the command directly in the terminal is correctly.

admin:
  deployCommand: './hexo-deploy.sh'

and I try it on the ubuntu, it's OK. I think windows doesn't support it.

[pirtleshell]

I think it's a permissions or shebang problem like from the posts mentioned above. You'll just have to play around with it to get it to work with Windows.

What are the contents of hexo-deploy.sh?

Does deploying work when you start hexo with administrative privileges (sudo hexo server)?

If that doesn't work, try setting deployCommand to the following and see if either of them work:

• hexo deploy
• sh hexo-deploy.sh
• node ./node_modules/hexo/bin/hexo deploy

[xbotao]

The contents of hexo-deploy.sh

#!/usr/bin/env sh
hexo g && hexo d

$ sudo hexo s -d
bash: sudo: command not found

I found a compromise method to deploy blog by click the deploy button.

create a hexo-deploy.bat file

hexo d

and set the deployCommand to deployCommand: 'hexo-deploy.bat' But a cmd console will pop when click the deploy button.

[xbotao]

Accoding to this issue(Using nodejs's spawn causes “unknown option — ” and “[Error: spawn ENOENT]” errors) I change //var proc = spawn(command, [message], {detached: true}); to var proc = spawn((process.platform === "win32" ? "hexo.cmd" : "hexo"), ['d']);

It works! Thanks for your patiently reply.

[xbotao]

sorry, just spawn((process.platform === "win32" ? "hexo.cmd" : "hexo"), ['d']); is not correctly.

need generate before hexo d

var proc = spawn((process.platform === "win32" ? "hexo.cmd" : "hexo"), ['d', '-g']);

[xbotao]

what I alter.And I test it on win10 and ubuntu. api.js deploy.js#L13 deploy.js#L16

[xbotao]

Could you test this code and pull it? @PirtleShell

[pirtleshell]

This is good to know, but the idea of deployCommand is that many things can be run on deployment, not just hexo d -g. I think limiting deployment to just this one command would be a regression. Did you try setting hexo.cmd d -g as your deployCommand in _config.yml?

The batch file also worked for you, so I think the current functionality is good. This is a great thread for someone who has problems with deploying on windows in the future though! Thanks for the thorough explanation!

[xbotao]

Got it.I think you mean，the current functionality cloud run any command you want rather than hexo g.

[pirtleshell]

That's right :smile: And it works on windows given the right command.

[xbotao]

Accoding to the exec function define

 if (process.platform === 'win32') {
file = 'cmd.exe';
args = ['/s', '/c', '"' + command + '"'];
// Make a shallow copy before patching so we don't clobber the user's
// options object.
options = util._extend({}, options);
options.windowsVerbatimArguments = true;
} else {
  file = '/bin/sh';
  args = ['-c', command];
}

I think this can do like this on windows: create a .bat file, content is

hexo deploy

and the deploy.js code is

  var proc;
  if(process.platform === "win32"){
    proc =  exec('hexo-deploy.bat');
  }else{
    proc = spawn(command, [message], {detached: true});
  }

the result is:

There is a disadvantage of exec command, the options' maxBuffer is limited to 200k. But I think 200K is enough in this enviroment.
