Installing Python Client Fails on grpcio 1.38.0

I’m trying to install typedb-client for python. I’m running python 3.10 and the latest version of pip. Here is the output from an attempted pip install. The typedb protocol was successfully installed, but the installation errored on grpcio.

[Note: there is a prior Topic: “Dependency on grpcio 1.24.1” with a similar problem. That problem was resolved by upgrading the grpcio version.]

Hi @MikeM,

Thank you for reporting! Could you please post the complete log of the error (preferably as a text file)? It looks like the one you’ve pasted isn’t complete.

Here’s the complete error log.

It looks like this is the most relevant bit highlighting the issue:

    distutils.errors.DistutilsPlatformError: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

Could you try obtaining said tool (C++ compiler & build tools from Microsoft) and try again?

I saw the same line a couple of days ago. I downloaded and installed “Microsoft Visual C++ 2015-2022 redistributable (x86)”. However, after installation, the problem continued. I thought that these VC++ redistributables are supposed to serve the same purpose as the full compiler and build tool package. But not in this case.

Today I downloaded the full Visual Studio package, which did work - up to a point. The grpcio installation started but errored on:

I’ve attached the full error output.
