“ERROR:root:code for hash md5 was not found” when using any hg mercurial commands

問題：

When trying to use any hg Mercurial commands on the console, I keep getting this error.嘗試在控制檯上使用任何hg Mercurial 命令時，我不斷收到此錯誤。 I installed Python using Homebrew and I am running Mac OS Catalina v. 10.15.1.我使用 Homebrew 安裝了 Python，我正在運行 Mac OS Catalina v. 10.15.1。

Any reference would be appreciated.任何參考將不勝感激。 Here is the error I'm getting:這是我得到的錯誤：

I also tried following the instruction on this issue but none of the solutions seem to work我也嘗試按照有關此問題的說明進行操作，但似乎沒有任何解決方案有效
