在 Mac OS XI 上運行gem install sqlite3命令時遇到以下錯誤消息：

我對使用終端、ruby on rails 和 ruby gems 比較陌生，現在已經摸不着頭腦（即搜索谷歌）幾個小時了，如果有任何幫助，我將不勝感激。 已經嘗試過sudo命令但沒有運氣。

Answer 1

你應該先在你的 OSX 中安裝 sqlite3

brew install sqlite3

Answer 2

好吧，最后我把廚房的水槽扔到了這個地方。 以下是我為解決該問題所采取的步驟。

1. 已卸載的 RVM 鏈接
2. 卸載 App Store 版本的 xcode，因為它以前安裝過鏈接
3. 在終端中運行$ xcode-select --install以安裝命令行工具

4. 因為我已經安裝了 Homebrew，所以我在 $PATH 鏈接的前面添加了 Homebrews 二進制路徑

   $ echo 'export PATH=/usr/local/bin:$PATH' >> ~/.bash_profile $ source ~/.bash_profile

5. 運行$ brew install sqlite3命令
6. 重新安裝 RVM

我認為最能緩解問題的步驟是 2、3、4 和 5。

希望這可以幫助！

我對使用終端、ruby on rails 和 ruby​​ gems 相對較新，並且已經撓頭（即搜索谷歌）幾個小時了，任何幫助將不勝感激。 嘗試過sudo命令，但沒有運氣。
