I'm trying to use the PyTrends module that is available on Github (here). To use this script I need to install the fake-useragent module with:

pip install fake-useragent

However, every time I import the file and attempt execute commands in console, I get the following error:

>>> from pytrends2.pyGTrends import pyGTrends
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pytrends2.py", line 18, in <module>
    from fake_useragent import UserAgent
ImportError: No module named fake_useragent

I've tried different things and had no luck. When trying to make sure the dependency modules are installed with: 

pip install pyyaml ua-parser user-agents

... I get the following:

     modify the parameter include_dirs in setup.cfg)

  • I clicked on the link you gave and it said to do `sudo pip install pytrends`. is this the right module? – Jonah Fleming Nov 04 '15 at 09:44

    Your pyyaml installation failure can be addressed by installing the right development packages; see [this answer](https://stackoverflow.com/a/37134143/1748148) for details. Once you've sorted that out, you might have more luck. – gowenfawr Feb 10 '18 at 17:32

You probably want to install the development libraries for your Linux first. Make sure you have all development packages installed.

If you do operate on Ubuntu try to run this first

sudo apt-get install gcc libyaml-dev libpython2.7-dev

You will be able then to install your required python libraries. 

pip install pyyaml ua-parser user-agents fake-useragent

Best wishes
