Installing Homebrew on macOS

Question

When I tried to install homebrew using this command:

brew install wget

I am getting this error in return:

-bash: brew: command not found

 I got this answer after some research but the issue is that I can find brew in /usr/local/bin.

To solve this I added the below line to my .bashrc file

export PATH=/usr/local/bin:$PATH

But I am still getting this error. Can someone help me solve this?
