HG-Git: AttributeError: 'bytes' object has no attribute 'encode'

Question

我正在尝试使用 mercurial 和 hg-git 克隆一个 git 存储库，但不断出现 AttributeError。当我运行 hg clone git://github.com/michaelfm1211/simpleserve 时，我得到的输出是这样的：

AttributeError: 'bytes' object has no attribute 'encode'

我不知道为什么会这样。我用 brew install hg 安装了 Mercurial，用 ~/brew/opt/python@3.8/bin/easy_install-3.8 hg-git 安装了 hg-git，因为我已经配置 Homebrew 安装到 ~/brew 而不是 /usr/local.

AttributeError: 'bytes' object has no attribute 'encode'

首先检查您用于 Mercurial 的 python 版本。

~/brew/opt/python@3.8 表示可能 Python 3.

然而：This hg-git thread提到：

hg-git does not work yet on Python3, but support may be coming soon.

hg-git can’t run that far on Python 3 and I suspect that you’re actually running Mercurial on Python 2.

参见hg-git issue 298。
