无法安装旧的 ruby​​ 版本

Question

I am unable to install ruby 2.4.2

My setup must allow me to use nvm and rvm , and I need to use ruby versions 2.7.2 and 2.4.2 . I suspect you may find multiple problems with my openssl and rvm setup. Also, I am not sure which version of openssl is appropriate for me. I am using macOS Monterey Version 12.3.1 .

When I do:

 rvm install 2.4.2

I see this error in my ..._ruby-2.4.2/configure.log

configure: error: something wrong with LDFLAGS="-L/opt/homebrew/opt/openssl@1.1/lib"

The following info may relate to the problem:

openssl version # LibreSSL 2.8.3

~/.zshrc

export PATH=$HOME/bin:/usr/local/bin:$PATH
export PATH="/opt/homebrew/bin:$PATH"
export PATH="/opt/homebrew/sbin:$PATH"

export CPPFLAGS="-I/opt/homebrew/opt/openssl@1.1/include"
export RUBY_CFLAGS="-DUSE_FFI_CLOSURE_ALLOC"

I identified two problems:

1. My LDFLAGS had the wrong path in ~/.zshrc
2. I did not understand why openssl version produced LibreSSL 2.8.3

I found the correct path to the LDFLAGS within the errors produced by brew reinstall openssl@1.1 . The errors included:

For compilers to find openssl@1.1 you may need to set:
export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"

The response to openssl version is still LibreSSL 2.8.3 and I assume this is correct.

I have also learned that ~/.zshrc must include source ~/.bash_profile , and that ~/.bash_profile must include source ~/.bashrc .

I am now able to open a new shell window and see the correct results for rvm list (listing the available ruby versions) and nvm list (listing the available node versions).

I am also able to install the ruby versions I want.
