Ruby 安裝 (2.2.2) 在 macOS Big Sur 中失敗

Question

我在 macOS Big Sur 上安裝 Ruby 2.2.2 時遇到了一些麻煩。 有沒有人遇到過他們能夠解決的類似問題？ 非常感謝

錯誤：

看起來 OP 編輯了原始消息中的錯誤，因此以下答案不再相關。 留在這里留給后人。

更新的答案

基於 rbenv repo 上幾個 Github 問題的討論，

• https://github.com/rbenv/ruby-build/issues/1480
• https://github.com/rbenv/ruby-build/issues/1489

聽起來 Apple 將默認CFLAGS更改為 xcode 12 的一部分，這使得一些本機擴展安裝 go 變得混亂。 聽起來這些問題中提出的解決方案是

CFLAGS="-Wno-error=implicit-function-declaration" rbenv install 2.2.2

原始答案

該錯誤指出由於擴展問題而失敗

The Ruby readline extension was not compiled.
The Ruby zlib extension was not compiled.
ERROR: Ruby install aborted due to missing extensions

所以我建議先嘗試手動安裝這些擴展，然后重試 ruby 安裝。

用沖泡：

brew install readline
brew install zlib

ruby-build的 github 也有一些問題可能會有所幫助：
