[jacob m]

Hi guys
I have some problems with gmpy2 module installation - pip install gmpy2
doesn't work for me

How to fix it?

Hi Jacob,

I'm afraid the screen-shot that you sent was automatically stripped off
by the mailing list. Could you copy the error text (preferably
cut-and-paste the whole thing rather than retyping!)? The more
information you can give us, the better the advice will be from the
people who actually understand pip :-)

Replying to the list since I have absolutely no idea about gmpy2 or pip...

A little googling suggests that you need to install the libgmp3-dev package:

$ sudo apt install libgmp3-dev

Sorry Rhodri, my gmail set your email as default recipient when I was
responding, I forgot to change that. Sorry for that
