  </code></pre>
  <p>Then I tried to run it in the same shell</p>
  <pre><code>bazel run //packages/path
  </code></pre>
  <p>I got such error</p>
  <pre><code>ImportError: Python version mismatch: module was compiled for Python 3.6, but the interpreter version is incompatible: 3.8.10 (default, Mar 15 2022, 12:22:08) 
  [GCC 9.4.0].
  </code></pre>
  <p>I do have python3.6 and python3.8 installed, and both are available at
  <code>/usr/bin/</code>.</p>
  <p>The default python is 2.7</p>
  <pre><code>➜  sdk git:(master) ✗ which python                                       
  /usr/bin/python
  ➜  sdk git:(master) ✗ python --version
