Unable to install grpcio using pip install grpcio

Question

I am getting error while installing grpcio using pip install grpcio on my windows machine.I read here - https://github.com/grpc/grpc/issues/17829 that it may be due to error in a version of setuptools. I upgraded my setuptools to the latest version i.e. 41.0.1 . Still getting the same build error. Its not happening for any other package. I have tried reinstalling pip and python both on my laptop. I'm attaching my error

Answer 1

First, upgrade pip

pip3 install --upgrade pip 

Then, update the setup tools:

python3 -m pip install --upgrade setuptools 

---

At last, install grpcio using :

pip3 install --no-cache-dir  --force-reinstall -Iv grpcio==<version_number>
