解決pip install XX時出現Could not find a version that satisfies the requirement opencv (from versions: )

1.問題描述

在裝pip install debacl時出現瞭如下錯誤:

Could not find a version that satisfies the requirement debacl (from versions: )
No matching distribution found for debacl

試了很多次依然報錯,有的是碰牆了,需要去官網下載軟體包,手動安裝。仔細找了下,是虛擬機器網路不穩定的原因,重新連線網路就OK
