使用任何hg mercurial命令时，“找不到哈希md5的ERROR：root：code”

Question

尝试hg在控制台上使用任何Mercurial命令时，我一直收到此错误。我使用Homebrew安装了Python，并且正在运行Mac OS
Catalina v.1.5.1。

任何参考将不胜感激。这是我得到的错误：

hg commit --amend

我也尝试按照有关此问题的说明进行操作，但似乎没有一种解决方案能起作用

brew link openssl --force
Warning: Refusing to link macOS-provided software: openssl@1.1
If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"

For pkg-config to find openssl@1.1 you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

Answer 1

brew reinstall python@2对于我现有的Python 2.7虚拟环境，运行不起作用。在他们里面仍然有ERROR:root:code for hash sha1 was not found错误。

我跑步后遇到了这个问题brew upgrade openssl。解决方法是：

$ ls /usr/local/Cellar/openssl

…这表现了

1.0.2t

根据现有版本，运行：

$ brew switch openssl 1.0.2t

…这表现了

Cleaning /usr/local/Cellar/openssl/1.0.2t
Opt link created for /usr/local/Cellar/openssl/1.0.2t

之后，在Python 2.7 virtualenv中运行以下命令：

(my-venv) $ python -c "import hashlib;m=hashlib.md5();print(m.hexdigest())"

…这表现了

d41d8cd98f00b204e9800998ecf8427e

没有更多的错误。
