aws cli: ERROR:root:code for hash md5 was not found

Question

When trying to run the AWS CLI, I am getting this error:

aws

I tried the solution from this issue but they do not work:

brew reinstall python@2
==> Reinstalling python@2
Error: An exception occurred within a child process:
  FormulaUnavailableError: No available formula with the name "/usr/local/opt/python@2/.brew/[email protected]"

I thought it might not be installed, but it already is:

brew install python@2
Warning: python@2 2.7.15_1 is already installed and up-to-date
To reinstall 2.7.15_1, run `brew reinstall python@2`

Running brew doctor shows that python is unliked, but running brew link python fails because of a symlink belonging to python@2.

brew link python
Linking /usr/local/Cellar/python/3.7.6_1...
Error: Could not symlink Frameworks/Python.framework/Headers
Target /usr/local/Frameworks/Python.framework/Headers
is a symlink belonging to python@2. You can unlink it:
  brew unlink python@2

To force the link and overwrite all conflicting files:
  brew link --overwrite python

To list all files that would be deleted:
  brew link --overwrite --dry-run python

The commands recommended seem to go in circle and none of them manage to solve the issue. I am a bit stuck - how do I recover from these errors?

Solution

Ran into a similar issue with brew install python2 error when trying to use pip.

It's probably because

python@2 was deleted from homebrew/core in commit 028f11f9e:
python@2: delete (https://github.com/Homebrew/homebrew-core/issues/49796)
EOL 1 January 2020.

See this post here https://github.com/Homebrew/homebrew-core/pull/49796 for more details.

To fix this,

1. run brew uninstall python@2 to uninstall brew installed python@2 this should make default python2 fall back to python2 came with macOS.

2. uninstall current aws cli by running

   • sudo rm -rf /usr/local/bin/aws
   • sudo rm -rf /usr/local/aws
   • rm AWSCLIV2.pkg

3. install aws cli again by running

   • sudo curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"
   • sudo installer -pkg AWSCLIV2.pkg -target /

4. if you run aws --version you should see it's linked to python3 instead of python2.

Hope it helps.

I recommend you to purge that version from your system, and download the new AWS CLI v2, which is provided by a bundled package to prevent such dependencies with Python

@eez0 I can try, but I am running in the same issue:pip uninstall awscli ERROR:root:code for hash md5 was not found.

[Doyin Olarewaju]

Try brew reinstall awscli

[BJYC]

Might also do, $ brew uninstall python@2, if it is not used anymore.

Mojave 10.14 - after brew uninstall python@2 - aws cli it gets linked to python3 with no issue.

I got an curl error with 3., it's easier to install AWS CLI by following their instruction at docs.aws.amazon.com/cli/latest/userguide/install-cliv2-mac.h‌​tml
