On doing bundle install for this rails project, i am facing with this issue.
My Mac details
- Chip - Apple M1 Pro
- macOS - 13.4.1
I have gone through most of the other articles based on the same issue, but nothing seems to solve the issue. On bundling it should install all the gems without any error.
I have already installed postgresql and libpq
On doing gem install pg
Building native extensions. This could take a while...
