title: twine not found (-bash: twine: command not found)
body: <p>I am trying to use twine to publish my first python package on pypi (of course will add on test-pypi first). </p>
  
  <p>I followed the official guideline on <a href="https://packaging.python.org/tutorials/packaging-projects/" rel="noreferrer">https://packaging.python.org/tutorials/packaging-projects/</a>. </p>
  
  <p>But for some reason, twine is not found or not properly installed. </p>
  
  <p>I installed twine using: </p>
  
  <pre><code>pip install twine
  </code></pre>
  
  <p>"pip list" says twine is installed on pip.</p>
  
  <p>After I upgraded twine and everything, when I tried to run: </p>
  
  <pre><code>twine upload --repository-url https://test.pypi.org/legacy/ dist/*
  </code></pre>
  
  <p>then it says that twine is not found at all:</p>
  
  <pre><code>-bash: twine: command not found . 
  </code></pre>
  
  <p>My system is mac (high sierra) and I am using python2.7 by conda. Pip is also configured to conda python:</p>
  
  <pre><code>&gt;&gt;pip -V 
  &gt;&gt;pip 10.0.1 from /anaconda2/lib/python2.7/site-packages/pip (python 2.7)
  </code></pre>
  
  <p>I would appreciate your help. </p>
