Hi,

make[1]: Leaving directory `/home/apmosys123/Projects/ESP32/esp-idf/tools/kconfig'
GENCONFIG
The following Python requirements are not satisfied:

Please run "/usr/bin/python2 -m pip install --user -r /home/apmosys123/Projects/ESP32/esp-idf/requirements.txt" for resolving the issue.
make: *** [check_python_dependencies] Error 1

I am not able to resolve this issue.Please help asap

What is your OS? have you tried to run this command:

/usr/bin/python2 -m pip install --user -r /home/apmosys123/Projects/ESP32/esp-idf/requirements.txt

I had a problem on windows using this command and somewhere someone said that for windows the update should be done with packman instead of with pip. I don't know if they have fixed this yet

I set up a friend's win 10 laptop with the latest master IDF and had the same problem. Fixed it by going back to the v3.1 release. However there is at least one other thread on this forum addressing how to fix this problem.

My version for ESPIDF is 3.1 i.e the stable one and m working on Ubuntu14.04..i have tried the commands mentioned below ,which i researhed from my forums

/usr/bin/python2.7 -m pip install --user -r /home/apmosys123/Projects/ESP32/esp-idf/requirements.txt

sudo pip install --upgrade setuptools

But still there is same error. Cant resolve.
But after being wasted 2 days in dis issue I commented the cryptography in requirements.txt file like
#cryptography

And then compiled, and yes the program got compiled successfully and also got flashed on ESP32.
But still cant understnd the cryptography thing and will it be neccesary in future puropse.
