Compilation error building pycrypto-2.6.1. Please ensure a C compiler is installed and functional on your system

[Дети и Еда Ольга Язькова]

Please help me. Where can i take C compiler on win10 and how should I install it?

I want to create my online course, but already can't install because of this mistake.

Hello,

On App Engine Standard, pycrypto is built into the runtime [1]. For local testing, you must run 'gcloud component install app-engine-python-extras' [2].

If you are still experiencing issues, I suggest posting this on Stackoverflow with more details about what you have done so far including code. 

If you are using Course Builder, you can try posting in that community as well [3].
