How to put geckodriver into PATH?
<p>I'm on OS Sierra and i'm running Python 3.5.2. I have selenium installed and i'm following a book called "Automate the Boring Tasks With Python"</p>

<p>My code is </p>

<pre><code>from selenium import webdriver
&gt;&gt;&gt; browser = webdriver.Firefox()
</code></pre>

<p>I keep receiving the error </p>

<pre><code>Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/selenium/webdriver/common/service.py", line 64, in start

During handling of the above exception, another exception occurred:

browser = webdriver.Firefox()

</code></pre>

<p>I have searched far and wide for solutions to my issue. Many people have the same issue.. but none of the solutions are working. I have geckodriver copied everywhere in my Python folders. I've tried using terminal and I have tried specifying the path within the code and it still gives me errors. I hope somebody can help me. I'm sorry if this is in the wrong format, I don't know what i'm doing.</p>
