python - 如果我使用 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。几个月前还可以，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

显然我的 Python 安装有些问题。我已经在这个问题上折腾了近 45 分钟(主要是重新安装所有内容并尝试一些帖子 like this one )，但我并没有比开始时更接近解决它。

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
