就像上次的github actions 上遇到的
原本跑得好好的 CI pipeline 又又又死掉了
Error Message
這次是在 CircleCI 中，設定 Python 的環境時，遇到以下的錯誤訊息
Traceback (most recent call last):

而且在我還無法在 local 重現 😱
Root Cause
terminal / tty 的視窗大小設定在不正常的大小
Solution
雖然問題根源是問同事才知道的，但後來有看一下其他人是不是遇到同樣的問題
根據這個討論 好像是 CircleCI 的 bug
至於為什麼會突然出錯，我就沒研究到那麼細了
寬度 -2 到底是搞什麼...
解決方案也很直覺，只要把 tty 設定到正常的大小，就不會遇到相似的錯誤了
stty cols 80
