如果我使用 pip3 安装了 AWS CLI，如何修复“dyld：Library not loaded”？

Question

I am trying to deploy a lambda with the AWS CLI. It was working a few months ago but now it's not.

Followed these instructions to install the CLI: https://docs.aws.amazon.com/cli/latest/userguide/install-macos.html

Results:

➜  lambda git:(master) ✗ pip3 install awscli --upgrade --user
Requirement already up-to-date: awscli in /Users/justin/Library/Python/3.7/lib/python/site-packages (1.16.310)
[... and so on, it's already installed] 

➜  lambda git:(master) ✗ brew uninstall awscli
Error: No such keg: /usr/local/Cellar/awscli

➜  lambda git:(master) ✗ python --version
Python 2.7.17

➜  lambda git:(master) ✗ pip3 --version
pip 19.3.1 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)

➜  lambda git:(master) ✗ python3 --version
Python 3.7.6

➜  lambda git:(master) ✗ aws --version
dyld: Library not loaded: @executable_path/../.Python
  Referenced from: /usr/local/aws/bin/python2.7
  Reason: image not found
[1]    42316 abort      aws --version

Clearly something is borked with my Python install. I've been messing around with this for close to 45 minutes now (reinstalling everything mostly and trying some posts like this one ) but I'm no closer to solving it than I was when I started.

Chip Cullen had the fix: https://chipcullen.com/fixing-bad-interpreter-error-aws-python-3_7/

This is because you've probably installed awscli in the past, but more recently upgraded your system Python to version 3.7, not 3.6 (which old versions of awscli worked with).

Short version:

brew reinstall awscli

brew link --overwrite awscli
