為什麼每當我鍵入無意義的命令時都會生成此 python 錯誤消息？
每當我鍵入任何“廢話”命令時，都會生成此 python 錯誤消息。普通命令工作正常。知道如何調試嗎？

$ yetanothernonexistingcommand Traceback (most recent call last): File "/usr/lib/command-not-found", line 10, in <module> import CommandNotFound ImportError: No module named CommandNotFound不知何故，每當我輸入錯誤的命令時，python 就會執行。
好的，這使事情變得更清楚了。
command-not-found是一個 python 程序，當你的命令在系統上找不到時執行。（其功能是在輸入錯誤等情況下提出替代方案和更正建議。）請參閱/usr/bin/command-not-found。它正在嘗試導入CommandNotFound模組並且無法導入，這清楚地指向了一個搞砸的 python 安裝。我不太熟悉command-not-found，但我認為修復您的 Python 安裝將使問題消失。只是為了詳細說明一下，可能發生的事情是該
command-not-found模組位於您的預設 python 不尋找它的某個地方。基本上是路徑問題。調試建議：
- 首先，輸出是什麼
$類型蟒蛇
該文件屬於什麼包/安裝？
- 與以下程式碼相對應的安裝輸出是什麼？這裡的路徑就是這個python的導入路徑。
