Getting error "No package 'libffi' found" when installing python-telegram-bot

Question

I tried to install python-telegram-bot on my raspberry pi but I got this problem:

I tried this command but I got the same problem:

pip install python-telegram-bot==12.0.0b1 --upgrade 
pip install python-telegram-bot --upgrade
python -m pip install python-telegram-bot

Is that the _entire_ error message? Can you check again to see if there are more error messages. — Gino Mempin, May 07 '19 at 23:48

It seems the main problem is this:

  Package libffi was not found in the pkg-config search path.
  Perhaps you should add the directory containing `libffi.pc'
  to the PKG_CONFIG_PATH environment variable
  No package 'libffi' found

That Python package you are installing requires CFFI which requires libffi.

Try installing libffi first:

$ sudo apt-get update
$ sudo apt-get install libffi-dev

If you are on a non-standard OS (not Raspbian) that you can't use apt, you can manually download and install the libffi-dev files directly from Debian or build it on your own from OpenEmbedded.
