brew-install | Clojure CLI installer | Command Line Interface library

I'm trying to install an older version of CMake to compile a software that requires it (https://github.com/horosproject/horos)

If you use brew install cmake it will install 3.20 versions, but I need to install 3.19.2 to get the compilation to work.

You would think this would be easy but I have been struggling. Here are some things I have tried:

Below is some necessary context for understanding my questions (my shell is /bin/bash by the way):

I'm following this tutorial to install mariadb on macOs Mojave. And I'm still have an issue when I try to secure it with mariadb-secure-installation

I tried writing a macOS Swift app that launches an executable in /usr/local/bin (e.g. Homebrew-installed /usr/local/bin/cowsay).

However, this does not work because /usr/local/bin is not in the PATH environment variable.

Within the app, I tried adding /usr/local/bin to PATH via setenv, which also doesn't seem to work.

Here is a code reproducer with Xcode 12.5 beta 3 (12E5244e):

I have been recently been trying to get started with GTKmm on my MacBook, and I have installed lots of the dependencies using Homebrew. However, when I go to compile my program, I get this error:

In the past I am reasonably confident that I had used a postgres user on macOS. However I do not see it on the brew-installed version on my catalina laptop:

I run brew install mysql or brew install mariadb then mysql_install_db and mysql_secure_installation but since I don't know the mysql password I just keep getting Access denied for user 'root'@'localhost' errors. It says it created root@localhost user with no password but I have to be the root system user. It also said it created another user without a password but I can't connect with that user either.

I've tried both of these solutions and nothing works:

• brew install mysql on macOS
• Reset MySQL / MariaDB password on OSX

Along with a couple other tutorials but it always comes back to needing to know the current password and I get stuck. Has anyone else had any luck installing mysql or mariadb on macos with brew?

Edit: I uninstalled and reinstalled and even after deleting /usr/local/var/mysql, when I run mysql_install_db it says mysql.user already exists so it can't install. How do I remove all databases when uninstalling?

Edit 2: So I think I finally managed to change the password but I keep getting this error message while trying to do mysql_secure_installation: Enter current password for root (enter for none): /usr/local/bin/mysql_secure_installation: line 249: .my.cnf.29733: Permission denied /usr/local/bin/mysql_secure_installation: line 250: .my.cnf.29733: Permission denied /usr/local/bin/mysql_secure_installation: line 251: .my.cnf.29733: Permission denied /usr/local/bin/mysql_secure_installation: line 253: .my.cnf.29733: Permission denied /usr/local/bin/mysql_secure_installation: line 218: .mysql.29733: Permission denied /usr/local/bin/mysql_secure_installation: line 220: .mysql.29733: No such file or directory

I was install HomeBrew，bec my area and network problem, terminal tells me:

I have a brew-installed version of Postgres 12.3 running on my mac.
