title: "exec: "python": executable file not found in $PATH
body: <p>I am running <strong>Arduion IDE 1.8.12</strong> on <strong>Ubuntu 18.04.4 LTS</strong>.</p>
  
  <p>I am trying to compile Example code for ESP32 Camera module (standard camera module with default example on Arduino IDE) and I got this error (which I think is not Arduino issue, but Python):</p>
  
  <pre><code>"exec: "python": executable file not found in $PATH
  Error compiling for board ESP32 Wrover Module" 
  </code></pre>
  
  <p>Same message with all ESP32.</p>
  
  <p>I also did sudo apt install python. Got back this:</p>
  
  <pre><code>Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  python is already the newest version (2.7.15~rc1-1).
  0 modernizētas, 0 instalētas no jauna, 0 tiks noņemtas un 6 netiks modernizētas.
  </code></pre>
  
  <p>When I type Python in Terminal, got this back:</p>
  
  <pre><code>Python 2.7.17 (default, Nov  7 2019, 10:07:09)
  [GCC 7.4.0] on linux2
  Type "help", "copyright", "credits" or "license" for more information.

  <p>Thank you for help!</p>
