Maybe you can give me a hand.

I am working with a Jupyter Notebook, on top of an Anaconda installation, in windows 7.

Seems like I was able to install ujson . But

pip install steem

gives this error message

error: command 'C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\x86_amd64\cl.exe' failed with exit status 2
