How to add Chromedriver to PATH in linux? : <p>Trying to use Selenium with Chrome in a python script.</p>

<p>I get the following error:</p>

<pre><code>WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home
</code></pre>

<p>I know the location of the chromedriver executable. 
How do I add it to the PATH?</p>

<p>thank you</p>
