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

Question

我正在尝试使用AWS CLI部署lambda。几个月前它还在工作，但现在不行了

按照以下说明安装CLI:https://docs.aws.amazon.com/cli/latest/userguide/install-macos.html

结果:

➜  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

很明显，我的Python安装有问题。我已经在这个问题上胡闹了将近45分钟（主要是重新安装所有的东西，并尝试一些帖子），但我并没有比我开始的时候更接近解决这个问题

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).

简短版本：

brew reinstall awscli

brew link  overwrite awscli
