I got an error when installing datadotworld module involving cchardet. I have already installed that package but I am still getting this error. Please help me find a solution. Here is the the full error message:

Just spent an hour or so wrestling with this same error, so I had to come back and help you out too. What worked for me was going to the cchardet setup.py file on GitHub, and checking for dependencies that I didn't have installed. Turns out the only one I didn't have installed yet was Cython. I ran pip install cython, then pip install datadotworld[pandas] finally worked.
Hope this helps!
