package incompatability on pip install

[arvsr1988]

I created virtualenv with python 3.6 and ran pip install -r requirements.txt. I get this error.

moto 1.3.3 has requirement boto3>=1.6.16, but you'll have boto3 1.6.8 which is incompatible.
moto 1.3.3 has requirement botocore>=1.9.16, but you'll have botocore 1.9.8 which is incompatible.

pip install boto3==1.6.16
pip install botocore==1.9.16

if above commands didnt work try to upgrade pip install --upgrade --force-reinstall moto

make sure that the version of these library matchs with requirement.txt
pip show boto3 botocore moto
