Error installing postgresql through homebrew

Question

I was able to install homebrew with no issues, but when I try to install postgresql I get the below error messages:

➜  ~ brew install postgresql
Warning: No available formula with the name "postgresql".
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

Any idea how to fix this?

Answer 1

git -C $(brew --repo homebrew/core) checkout master

this will switch to master, then run

brew doctor

this should run without any error.

If there is no error you can install anything with brew install.

ex:

brew install postgresql

Answer 2

I had the same problem, and I fixed by running brew tap homebrew/core

After that, postgresql was available to install using:

brew install postgresql
