building 'postal._expand' extension error

[yunier-rojas]

Hi.
I'm trying to install pypostal on a alpine OS. libpostal was successfully compiled but I get this error doing:
pip install "postal==1.1.8"

The output of the command:

Any ideas?

It seems you don't have gcc available. Maybe you are removing the compiler before running the pip install? Or maybe a path problem?

I'm having the same issue. My gcc seems to work normally for other installs. Working on Ubuntu 18
