Modify the default PHP version under MAC system

I encountered a problem when using mac today, because composer needs to pull laravel5.6, but it prompts me that the php version is too old Low, but I personally use the integrated environment MAMP and have switched to the version of php7.2. Why does this not take effect? After checking, it was because composer detected that it was the PHP version in which the environment variables took effect under mac

$ which php
/usr/local/bin

Thoughts

At first, I wanted to uninstall the environment that comes with mac. I searched online and found all the results. Same thing, I deleted the directory on the left and on the right, but I couldn’t delete it now. When I deleted it under the root user, it prompted me that I didn’t have permission. I was surprised, and I went to Baidu as the root user and couldn’t delete the file, and then it said something about flags. , then I followed the steps to remove flags

#去除flags
Mac
[sudo] chflags nouchg filename

and then executed rm -rf and still got the same result

php: Operation not permitted
