title: Is it possible to use Cygwin on Windows to develop Node.js apps with Yarn?
body: <p>I would like to get started with, and use yarn.</p>
  
  <p>I am using cygwin on windows, I launch and type:</p>
  
  <pre><code>$yarn init
  </code></pre>
  
  <p>and I get:</p>
  
  <pre><code>$ yarn init
  yarn init v1.12.3
  error An unexpected error occurred: "Can't answer a question unless a user TTY".
  info If you think this is a bug, please open a bug report with the information provided in "C:\\home\\code\\repos\\pwa\\yarn-error.log".
  info Visit https://yarnpkg.com/en/docs/cli/init for documentation about this command.

  <h2>What does means: "Can't answer a question unless a user TTY"?</h2>
  
  <p>Am I prevented from using a bash shell provided by cygwin with yarn?  I could not find any document telling me what terminal/shell I should download and use.  </p>
  
  <p>I need to be productive using my bash shell with scripts, aliases, command line completion, and have access to a full range of gnu commands for scripting and so therefore a DOS command prompt or powershell is not an option.</p>
