Failed to build httptools, how to fix it

Question

When I try to install FastAPI. I am using Python 3.10.2, Pycharm.

I have already installed build tools which is given by the link. and updated setuptools, wheel and pip using

pip install --upgrade pip setuptools wheel

but I still get the following error with httptools.

The error message says: "Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": visualstudio.microsoft.com/visual-cpp-build-tools". Have you tried doing what it suggests? – Interrogatory

of course, but it didn't help. I have installed the Visual Studio 2019 Build Tools. – Merrymaking

Which version of httptools? httptools 0.4.0 has prebuilt whls for 3.10 (some earlier versions will only have 3.9, etc.): pypi.org/project/httptools/#files – Steeple

unfortunatly, dont really know. – Merrymaking

The version number will be specified in your requirements.txt file - or it will be present in the pip log when the package is attempted to be installed (slightly higher up than where the log in your question starts). – Steeple

After installing the Microsoft Visual C++ 14.0 build tools also some other error poped up. Updating the version number of httptools version from 0.4.0 to 0.5.0 in requirements file fixed the issue. – Formenti

Answer 1

Unfortunately I couldn't solve this problem using python 3.10
The only thing that helped me was rolling back to python 3.8.6 (it will probably work in python 3.9 as well)
As far as I understand, the problem is the incompatibility of the current version of httptools and python 3.10 If anyone finds a solution, be sure to write. I will wait.

Answer 2

Might want to try upgrading the version of httptools. I was able to build it for 3.10.9

Python 3.10.9 (main, Jan 11 2023, 09:18:20) [Clang 14.0.6 ] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import httptools
>>> httptools.__version__
'0.1.2

Answer 3

I resolved the same problem by adding the following libraries:

sudo apt install python3.10-distutils

sudo apt install python3.10-dev

Python version 3.10.13

Answer 4

belated updated, this was/is caused by httptools putting windows support at a lower priority and not releasing windows wheels as timely as linux ones. There have been many cases across the years of lack of windows wheels causeing this issue for various python versions. HttpTools will eventually release a windows wheel and it's fixed, until the next python version comes out and they once again don't bother to provide a windows wheel until enough people complain ;)

As of now up to 3.10 at least should have a windows httptools wheel and install without issue for most people. If you're stuck behind a firewall like me you will have to request an update to your pip mirror or downgrade your python. Trying to install visual C++ to build the wheel manually never seems to work.

given how frequently it's come up I wouldn't be surprised if at some point a new python also lacks a httptools wheel and a new generation of folks find this question and if so you will just have to downgrade or wait for them to put out a windows wheel.

Answer 5

The support for newer python versions comes a bit late on the library.

I did some build automation jobs on 09/10/2024:

• python 3.13.0 failed
• python 3.12.0 succeed
• python 3.11.0 succeed

further research: httptools github workflow file

Seems like they have not yet added support for the python3.13. You could switch to the latest supported python version.

From OP : I am using Python 3.10.2 – Scurvy

@Scurvy do note that the question was asked about 2.5 years ago. In all likelihood, 3.10.2 was that newest python version back then. This answer's notion that the latest python versions is unlikely to be supported would (probably) had held true back then and in the future too. – Triggerhappy
