title: RunTimeError: pdf Latex not install
body: <pre><code>$ schtex drawing.sch drawing.png
  </code></pre>
  <p>When I try to run the above code it says that I don't have pidflatex installed even though I have pip installed latex, tex, and pdflatex.
  I have also run the following lines when testing another piece of code and it failed to obtain anything:</p>
  <pre><code>from sympy.utilities.misc import find_executable
  find_executable('latex')
  </code></pre>
  <p>It also gave me an error</p>
