I try to setup a development environment for developing on django itself.
Docs: Contributing / Running the test suite for the first time
python -m pip install -r requirements/py3.txt
It fails:
...

What can I do to fix this?
For m1 mac:
Try install/reinstall
brew install libmemcached
and then
pip install pylibmc
If you still face the issue then try:
pip install pylibmc --install-option="--with-libmemcached=/usr/local/Cellar/libmemcached/1.0.18/"
Please note: Change libmemcached path according to your machine and package version for eg in my case path is /opt/homebrew/Cellar/libmemcached/1.0.18_2/
You need to install the development header files via your OS package manager:
For example on Ubuntu:
sudo apt install libmemcached-dev
