Installing ujson library for Python3.7 on Ubuntu 18.04?

Question

Python

Hello, after executing the following command in venv'e:
pip install ujson I
catch the following error:
Command "/home/user/projectname/venv/bin/python -u -c "import setuptools, tokenize;file='/tmp/ pip-install-n3llo159/ujson/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n' );f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-record-1m3j6w9l/install-record.txt --single-version-externally-managed - -compile --install-headers /home/user/projectname/venv/include/site/python3.7/ujson" failed with error code 1 in /tmp/pip-install-n3llo159/ujson/
I'm pretty sure I broke something- then in the system itself, and not in venv'e, because the same error occurs in other projects when installing ujson. The rest are installed without problems.

Try sudo apt-get install python3-dev first
