I'm using the Requests library with Python 2.7 and get the following error:

I installed Requests with the following command:
sudo pip install requests -t /usr/local/lib/python2.7/dist-packages
The file I'm running is just main.py with the content:
import json
import requests
if __name__ == "__main__":
print('hello world')
I have both Python 3.6 and 2.7 installed and selected Python 2.7 as the interpreter in VS Code.
I just ran into this issue; the package is expecting to be executed with Python 3, not Python 2.

Maybe just reinstall pip without pip?
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
See https://pip.pypa.io/en/stable/installing/ for more info.
I installed locustio
pip install locustio
Once installed, I tried running

Is the solution to rebuild gevent? If so, how does one go about rebuilding greenlet in debian virtualenv with python 2.7.3? If not, how do I solve this issue without upgrading python?
I'm having trouble getting numpy working with conda + python 2.7. It works fine with python 3, but when I try below I get "cannot import name scalarmath".
conda create -n test numpy python=2.7 --no-default-packages

python -c 'import numpy'

You need to activate your environment with source activate test. This works for me on OS X 10.9.:
conda create -n test numpy python=2.7 --no-default-packages
source activate test
python -c 'import numpy'
I use the Python distribution. Python 2.7 x64 with Windows 7 SP1 x64 Ultimate.
After a conda update --all, whenever I try to import matplotlib.pyplot I get ImportError: DLL load failed: %1 is not a valid Win32 application.. Why?

I had the same issue after running conda update anaconda. The solution that worked for me was to simply to download the latest windows installer, then uninstall and reinstall.
I suspect this is related to the pathname of your conda environment, as if you do a clean install anaconda now wants to live in C:\Users\yourname\AppData\Local\Continuum\Anaconda2, where previously it was just Anaconda (no 2). I suspect after running the upgrade scripts some things are pointing to the nonexistant (for you) "new" path.
I found that if I explicitly activate a conda environment with activate myenvname before running anything it works fine. Likewise if you you run from the "anaconda prompt" (which activates your default environment for you) it works fine. But to get my default environment to stay active from anywhere like its supposed to I had to reinstall.
Here is what worked for me:
Run conda update -f matplotlib (from the Anaconda command prompt)
This gave me a new error:

Run conda install anaconda. This rolled your system back to a stable anaconda distribtution, and solved the issue. (I guess you could skip steps 1 and 2, but I don't feel like going through it again to confirm…)
