问题
I have been looking to implement the example Python scripts I have found online to allow me to interact with the YouTube API as per the GitHub link found here
The problem I am having is with the import statement at the start:
import argparse
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
The online documentation requires the following command to install the googleapiclient library:
pip install --upgrade google-api-python-client
However, once installed I am still receiving an error that googleapiclient.discovery cannot be found. I have tried reinstalling via pip, with the following command line output generated, suggesting all is well:
Requirement already up-to-date: google-api-python-client in g:\python27\lib\site-packages (1.7.4)
Requirement not upgraded as not directly required: httplib2<1dev,>=0.9.2 in g:\python27\lib\site-packages (from google-api-python-client) (0.9.2)
Requirement not upgraded as not directly required: google-auth>=1.4.1 in g:\python27\lib\site-packages (from google-api-python-client) (1.5.0)
Requirement not upgraded as not directly required: google-auth-httplib2>=0.0.3 in g:\python27\lib\site-packages (from google-api-python-client) (0.0.3)
Requirement not upgraded as not directly required: six<2dev,>=1.6.1 in g:\python27\lib\site-packages (from google-api-python-client) (1.10.0)
Requirement not upgraded as not directly required: uritemplate<4dev,>=3.0.0 in g:\python27\lib\site-packages (from google-api-python-client) (3.0.0)
Requirement not upgraded as not directly required: rsa>=3.1.4 in g:\python27\lib\site-packages (from google-auth>=1.4.1->google-api-python-client) (3.4.2)
Requirement not upgraded as not directly required: cachetools>=2.0.0 in g:\python27\lib\site-packages (from google-auth>=1.4.1->google-api-python-client) (2.1.0)
Requirement not upgraded as not directly required: pyasn1-modules>=0.2.1 in g:\python27\lib\site-packages (from google-auth>=1.4.1->google-api-python-client) (0.2.2)
Requirement not upgraded as not directly required: pyasn1>=0.1.3 in g:\python27\lib\site-packages (from rsa>=3.1.4->google-auth>=1.4.1->google-api-python-client) (0.1.9)
pyasn1-modules 0.2.2 has requirement pyasn1<0.5.0,>=0.4.1, but you'll have pyasn1 0.1.9 which is incompatible.
What am I doing wrong?
Thanks

In case you are running Python3 (python --version), perhaps you should run this instead:
pip3 install google-api-python-client
Another quick way to counter this problem could be to install the package in the same folder as your code:
pip install google-api-python-client -t ./
That's not ideal but it will definitely work.
Or if you prefer to move external libraries to a lib/ folder:
pip install google-api-python-client -t ./lib
in that last case you will also need this at the beginning of your Python code:
import os
import sys
file_path = os.path.dirname(__file__)
module_path = os.path.join(file_path, "lib")
sys.path.append(module_path)
from googleapiclient.discovery import build
