title: ERROR when trying to build chromium on my own computer
body: <p>Right now, I am tring to build Chromium on my own computer under instructions at <a href="https://chromium.googlesource.com/chromium/src/+/master/docs/linux/build_instructions.md#Build-Chromium" rel="nofollow noreferrer">https://chromium.googlesource.com/chromium/src/+/master/docs/linux/build_instructions.md#Build-Chromium</a></p>
  <p>At first, it went smoothly. However when I run</p>
  <pre><code>$ autoninja -C out/Default chrome
  </code></pre>
  <p>when I run this to start build. It started. And then an error occured and the build process is terminated.</p>
  <p>The error is
  <code>NameError: name 'unicode' is not defined&quot;</code> and I know it is a common error associated with the difference between python2 and python3.</p>
  <p>However, I don't know how to let the ninja use only python2 and avoid this bug.</p>
  <p>If you can help me, I will really appreciate it.</p>
