Install the packages:
sudo apt-get install build-essential python3 python-dev python3-dev
After, run:
pip install --no-cache-dir ujson

I have the same issue on Windows 10.
I have tried all Python versions although no difference.
Tried many ways of installing Visual Studio although no difference.

[zhfneu]

you can try this comand to Install ujson separately.
conda install -c anaconda ujson

@zhfneu Thank you. installing byconda install -c anaconda ujson worked on Windows10

Sorry for my late reply. In my case it was due to MS Visual C++ 14.0. After following these steps my issue was solved:

I have selected Workloads C++ build tools and all three SDK additional install options.

@marboe123 Thank you for sharing your ultimate solution. It is fixed.

[PrimeTime416]

Thanks you worked like a charm, how did you figure this out, did I miss something in the documentation?

[marboe123]

I tried several settings based on this blog:

[aryabhatta000]

or download the wheels from here https://www.lfd.uci.edu/~gohlke/pythonlibs/#ujson

After downloading the correct Python version and System appropriate .whl file do this

pip install some-package.whl
pip install C:/some-dir/some-file.whl

stackoverflow reference on installing .whl file

Thank you, after trying for hours this finally worked. Anyone stuck on this just download the build tools file from this link and install it, if you have already downloaded it and not working just open installer again and select modify. While installing or modifying you will be prompted about what should be installed, in workload section select first option which should be C++ build tools and in individual components type sdk in search bar, select all 3 under .NET tab and install, thats it. This should fi your problem.

[vaishnavi-amalladinne]

uninstall the previous ujson version if you have ujson already
Try pip install ujson==1.35
I guess there are some incompatibility issues with later versions.
This worked for me on Windows 10

Solved for windows 10
