I encountered the same problem. If you look into the code in gulp/tasks/eslint.js, you'll find the following code:

spawn(
      process.execPath,
      [
        path.join('node_modules', '.bin', 'eslint' + extension),
        '.',
      ],
      {
        // Allow colors to pass through
        stdio: 'inherit',
      }
    )

which spawns a new process using the command "node node_modules.bin\eslint.cmd .". The command tries to interpret a batch file using node. However node can interpret js files only. That's why there's a SyntaxError.
A change like this should work as expected:

spawn(
      path.join('node_modules', '.bin', 'eslint' + extension),
      ['.'],
      {
        // Allow colors to pass through
        stdio: 'inherit',
      }
    )

@jddxf Would you like to send a PR if you have a working fix?

@gaearon Sure. I'll fix the same problem in gulp flow task too.
