幾天前，我遇到了 pip3 停止工作的問題。無論如何，我計劃升級我的 WSL2，所以我只是遷移到 Ubuntu 20。我無法安裝任何事物與 pip3.
使用 -vvv 會產生完全相同的結果 - 什麼都沒有。我已經嘗試過重新安裝：
sudo apt purge *python3-pip* && sudo apt install python3-pip
是的，我等了大約 20 分鐘，什麼事也沒發生。當我運行時，幫助選單有效pip3，該pip3 freeze命令有效，但安裝和卸載無效。可能無關緊要，但這是當我用 Ctrl+C 殺死它時收到的訊息：

我被難住了！這是一個非常煩人的錯誤。如果有必要的話，我將 WSL2 與 Microsoft Store 中的 Ubuntu 20.04 LTS 一起使用。謝謝你！

感謝評論中的 Anaksunaman，我明白了。我跟著這個帖子在 GitHub 上，它成功了！
事實證明，問題在於導出我正在使用的 X-Server 的 DISPLAY 變數。當我從 .bashrc 評論該行後，pip 再次工作。
如果有人可以解釋，我將不勝感激為什麼這行在評論中打破了它：
export DISPLAY=$(cat /etc/resolv.conf | grep nameserver | awk '{print $2; exit;}'):0.0
