Python 使用任何 hg mercurial 命令时出现“错误：root：未找到哈希 md5 的代码”

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

提问by poca

When trying to use any hgMercurial commands on the console, I keep getting this error. I installed Python using Homebrew and I am running Mac OS Catalina v. 10.15.1.

尝试hg在控制台上使用任何Mercurial 命令时，我不断收到此错误。我使用 Homebrew 安装了 Python，我正在运行 Mac OS Catalina v. 10.15.1。

Any reference would be appreciated. Here is the error I'm getting:

任何参考将不胜感激。这是我得到的错误：

I also tried following the instruction on this issue but none of the solutions seem to work

我也尝试按照有关此问题的说明进行操作，但似乎没有任何解决方案有效

Running brew reinstall python@2didn't work for my existing Python 2.7 virtual environments. Inside them there were still ERROR:root:code for hash sha1 was not founderrors.

运行brew reinstall python@2不适用于我现有的 Python 2.7 虚拟环境。他们内部仍然存在ERROR:root:code for hash sha1 was not found错误。

I encountered this problem after I ran brew upgrade openssl. And here's the fix:

我跑了之后遇到了这个问题brew upgrade openssl。这是修复方法：

$ ls /usr/local/Cellar/openssl

...which shows

...这表现了

1.0.2t

According to the existing version, run:

根据现有版本，运行：

$ brew switch openssl 1.0.2t

...which shows

...这表现了

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

After that, run the following command in a Python 2.7 virtualenv:

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())"

...which shows

No more errors.

没有更多的错误。

Managed to fix this by first unlinking openssl

通过首先取消链接 openssl 设法解决了这个问题

brew unlink openssl

And then reinstalling python

然后重新安装python

brew reinstall python@2

I also noticed that when running 'brew doctor' there was a warning related to an openssl folder found in /usr/local/include/node/. I deleted this folder before running the above commands (not sure if related)

我还注意到，在运行 'brew doctor' 时，有一个与 /usr/local/include/node/ 中的 openssl 文件夹相关的警告。我在运行上述命令之前删除了这个文件夹（不确定是否相关）

The case for me is that when I install dependencies of a django web app, it messes up the environment. When I type cd, it shows the same error.

我的情况是，当我安装 django Web 应用程序的依赖项时，它会弄乱环境。当我输入时cd，它显示相同的错误。

The problem was the openssllibrary, it can not find the correct ones.

问题是openssl图书馆，它找不到正确的图书馆。

If you are on Macintosh, you can type

如果您使用的是 Macintosh，则可以键入

ls /usr/local/Cellar/openssl

ls /usr/local/Cellar/openssl

to see all the versions,

查看所有版本，

brew switch openssl 1.0.XXXX

brew switch openssl 1.0.XXXX

to choose the available openssl version.

选择可用的 openssl 版本。

Then the error is gone :)

然后错误消失了:)

When I would import hashlib I would see an error message stating that hash md5 was not found.

当我导入 hashlib 时，我会看到一条错误消息，指出未找到 hash md5。

I was able to fix this problem by first unlinking openssl: brew unlink openssl

我能够通过首先取消链接 openssl 来解决这个问题： brew unlink openssl

Then I uninstalled python 2.7 using MacPorts: sudo port uninstall python27

然后我使用 MacPorts 卸载了 python 2.7： sudo port uninstall python27

Then I installed python 2.7 using MacPorts: sudo port install python27

然后我使用 MacPorts 安装了 python 2.7： sudo port install python27

Now importing hashlib works :)

现在导入 hashlib 工作:)

I had this issue recently (2020, May) with Google's GCP CLI. It also works on the obsolete Python 2.7.

我最近（2020 年 5 月）在使用 Google 的 GCP CLI 时遇到了这个问题。它也适用于过时的 Python 2.7。

This is a borked Python 2 installation problem. mBrew no longer correctly installs Python 2 gracefully, as no one cares about abondonware.

这是一个无聊的 Python 2 安装问题。mBrew 不再正确地正确安装 Python 2，因为没有人关心 abondonware。

Conda still installs Python 2 in an environment; I did that.

Conda 仍然在环境中安装 Python 2；我就是这么做的。
