錯誤：'/bin' 不可寫 - Homebrew 需要它，嘗試使用 'brew doctor' 修復它：要求安裝失敗，狀態為 1

Question

我想將我的 ruby 2.0 更新為 2.1，所以我這樣做了：

rvm install ruby-2.1.0

然后我收到這個錯誤：

ERROR: '/bin' is not writable - it is required for Homebrew, try 'brew doctor' to fix it!
Requirements installation failed with status: 1.

整個output是這樣的：

我在嘗試安裝 ruby​​-2.7.5 時遇到了同樣的問題。 我找到了這篇博文/文章。

本質上，在較新版本的 OSX 中， usr/local/bin和usr/local/share目錄受到保護，不會被寫入。 您將需要執行以下步驟：

1. 運行sudo chown -R `whoami`:admin /usr/local/bin
2. 輸入您的密碼（運行“sudo”命令時需要）
3. 運行sudo chown -R `whoami`:admin /usr/local/share
4. 然后運行您的安裝命令。

希望這可以幫助
