Ruby-build: Unable to install Ruby versions >= 2.7.2. The error is "dyld: Library not loaded" for libruby.2.7.dylib

[chmurph2]

I am unable to install Ruby versions >= 2.7.2. The error is "dyld: Library not loaded" error for libruby.2.7.dylib. The error for Ruby 3.0.0 is similar. I'm on macOS Big Sur.

Same error with Catalina (10.15.7) and xcode (Version 12.4 (12D4e))

Check your PATH. After removing .: (current directory), Ruby 2.7+ installs for me successfully.

The above works around the issue. Should Rubies 2.7+ fail to build when the current directory (.) is included in the PATH though?

[wowinter13]

I had the same issue, but it was another problem in the $PATH:

/Users/you/.rbenv/shims::/ # and so on...

Removing of second colon symbol helped. /Users/you/.rbenv/shims:/ # and so on...

[huyvohcmc]

I had the same error, but my OS is mac 10.15.7 and my path is as follow:

/Users/huyvo/.asdf/shims:/Users/huyvo/.asdf/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/go/bin:/Library/Apple/usr/bin:/Users/huyvo/.zinit/polaris/sbin:/Users/huyvo/.zinit/polaris/bin:/Users/huyvo/Library/Android/sdk/emulator:/Users/huyvo/Library/Android/sdk/tools:/Users/huyvo/Library/Android/sdk/tools/bin:/Users/huyvo/Library/Android/sdk/platform-tools:/Users/huyvo/.fzf/bin

I don't know what's wrong?

@huyvohcmc have you tried removing as many of those paths from your PATH to see if the problem goes away? If it does, then you can slowly add back each path until it breaks, then you'll know.

[huyvohcmc]

@chmurph2 Yeah it was Android SDK paths.
