title: missing google-api-python-client module error but installed
body: <p>I've just signed up for a Free Tier account on Google Cloud Platform and got api key to replicate this code:</p>
  
  <pre><code>import os
  import speech_recognition as sr
  from tqdm import tqdm
  
  with open("api-key.json") as f:
      GOOGLE_CLOUD_SPEECH_CREDENTIALS = f.read()
  
  r = sr.Recognizer()
  files = sorted(os.listdir('parts/'))
  
  all_text = []
  
  for f in tqdm(files):
      name = "parts/" + f
      # Load audio file
      with sr.AudioFile(name) as source:
          audio = r.record(source)
      # Transcribe audio file
      text = r.recognize_google_cloud(audio, credentials_json=GOOGLE_CLOUD_SPEECH_CREDENTIALS)
      all_text.append(text)
  
  transcript = ""
  for i, t in enumerate(all_text):
      total_seconds = i * 30
      # Cool shortcut from:
      # https://stackoverflow.com/questions/775049/python-time-seconds-to-hms
      # to get hours, minutes and seconds
      m, s = divmod(total_seconds, 60)
      h, m = divmod(m, 60)
  
      # Format time as h:m:s - 30 seconds of text
      transcript = transcript + "{:0&gt;2d}:{:0&gt;2d}:{:0&gt;2d} {}\n".format(h, m, s, t)
  
  print(transcript)
  
  with open("transcript.txt", "w") as f:
      f.write(transcript)
  </code></pre>
  
  <p>unfortunately Pycharm returns me this error I can't find anywhere:</p>
  
  <pre><code>line 20, in &lt;module&gt;
      text = r.recognize_google_cloud(audio, credentials_json=GOOGLE_CLOUD_SPEECH_CREDENTIALS)
    File "C:\Program Files (x86)\Python36-32\lib\site-packages\speech_recognition\__init__.py", line 920, in recognize_google_cloud
      raise RequestError("missing google-api-python-client module: ensure that google-api-python-client is set up correctly.")
  speech_recognition.RequestError: missing google-api-python-client module: ensure that google-api-python-client is set up correctly.
  </code></pre>
  
  <p>so i tried to install and upgrade google-api-python-client but nothing changes. </p>
