How to Fix AWS CLI Tools When Homebrew Breaks Python
I installed stunnel on my mac via homebrew. I wasn't expecting the Spanish Inquisition. Homebrew did a giant update including some craziness with Python. I'm not sure what happened, but it broke all my virtual environments. I thought those were supposed to be independent, but that's another story. They were easy enough to fix. I just blew them away and recreated them.
The other thing that went sideways was the AWS CLI. When I tried to run a command, I'd get this:
$ aws s3 sync some/file.txt s3://bucket/some/file.txt ... A bunch of scary error code... from hashlib import md5, sha1, sha256 ImportError: cannot import name md5*
Per this page, I uninstalled the remains of homebrew's pytyon 2 via:
brew uninstall python@2
After that, I tried another aws command:
$ aws s3 sync some/file.txt s3://bucket/some/file.txt zsh: /usr/local/bin/aws: bad interpreter: /usr/local/opt/python@2/bin/python2.7: no such file or directory
In fact, running just
aws by itself produces the same error
Figured it was time to start over. My next step was to reinstall aws-cli. The Amazon page for the aws-cli tool says to do updates the same way you did the initial install. I don't remember how I did that so I removed the existing install first. The note says to find your
aws command with
$ which aws /usr/local/bin/aws
The notes say to uninstall
aws_completer, but there are other files there as well:
aws.cmd. I deleted them with:
sudo rm /usr/local/bin/aws sudo rm /usr/local/bin/aws.cmd sudo rm /usr/local/bin/aws_bash_completer sudo rm /usr/local/bin/aws_completer sudo rm /usr/local/bin/aws_zsh_completer.sh
which again and there was another
aws command floating around:
$ which aws /Users/alans/Library/Python/3.7/bin/aws
I tried using it, but got a similar error:
$ aws zsh: /Users/alans/Library/Python/3.7/bin/aws: bad interpreter: /usr/local/opt/python/bin/python3.7: no such file or directory
The same set of files was showed up in the new directory:
$ ll /Users/alans/Library/Python/3.7/bin/ |grep aws -rwxr-xr-x 1 alans staff 834B Jun 11 2019 aws -rwxr-xr-x 1 alans staff 1.4K Jun 11 2019 aws.cmd -rwxr-xr-x 1 alans staff 204B Jun 11 2019 aws_bash_completer -rwxr-xr-x 1 alans staff 1.1K Jun 11 2019 aws_completer -rwxr-xr-x 1 alans staff 1.8K Jun 11 2019 aws_zsh_completer.sh
I deleted them as well and finally cleared the system of the
$ which aws aws not found
The Amazon page also talks about deleting:
But I didn't have that. So, I just moved on.
I installed aws-cli via the the mac gui and that got things working again.
aws --version aws-cli/2.1.1 Python/3.7.4 Darwin/18.7.0 exe/x86_64
Just installing over top might have worked, but the directions said to install the same way you did the first time. That's a poor UX, but it is what it is. Since I don't remember how I installed originally, I just nuked the site from orbit and started over. It's was the only way to be sure.
