之前使用的是 bash,自從使用 zsh 後，在執行 source ~/.bashrc 的時候出現下面的 command not found 的錯誤。

下面是錯誤資訊

輸出錯誤資訊 

這裡有個 stack overflow 的迴應資訊 
shopt command not found in .bashrc after shell updation 

解決 
博主在 linux 上利用 Anaconda 同時配置了多個版本的 python ，在修改了~/.bashrc 檔案企圖更改系統預設的 python 之後 ，在 zsh 上執行了 source ~/.bashrc 。很明顯這是個錯誤的認識

好吧，正確的做法如下：

將所需配置修改寫入~/.zshrc
執行 source ~/.zshrc
