Pycharm can not auto complete selenium package
<p>I install selenium through Python pip and write a simple file called  crawlTest.py, it works well.Later, I install Pycharm and try to  auto complete method  from selenium, but it doesn't work.  </p>

<p>I guess Pycharm didn't  know where I install selenium and an external library is needed.But I try by myself and search on google and StackOverflow, I didn't  get proper  solution.</p>

<p>I have read the flowing posts, but still not work. It is very useful and
 time-saving for those who use selenium and Pycharm if some one could give me .</p>

<p>here is post list I hava viewed:  </p>
