MacOs Catalina AWS CLI 错误“ImportError: cannot import name 'ssl' from 'urllib3.util.ssl_'”

Question

使用 Python v.3.7.2 运行 MacOs v10.15.v 和 AWS CLI 并产生错误 -

qwerty@qwerty-mbp > aws --version
Traceback (most recent call last):
  File "/usr/local/bin/aws", line 19, in <module>
    import awscli.clidriver
  File "/usr/local/aws/lib/python3.7/site-packages/awscli/clidriver.py", line 17, in <module>
    import botocore.session
  File "/usr/local/aws/lib/python3.7/site-packages/botocore/session.py", line 30, in <module>
    import botocore.credentials
  File "/usr/local/aws/lib/python3.7/site-packages/botocore/credentials.py", line 42, in <module>
    from botocore.utils import InstanceMetadataFetcher, parse_key_val_file

    import botocore.httpsession

    from urllib3.util.ssl_ import (
ImportError: cannot import name 'ssl' from 'urllib3.util.ssl_' (/usr/local/aws/lib/python3.7/site-packages/urllib3/util/ssl_.py)

任何指针将不胜感激！

我遇到了同样的问题。你可以验证ssl模块没有安装在python发行版中：

 /usr/local/Cellar/python@3.8/3.8.3_2/bin/python3
Python 3.8.3 (default, Jul 10 2020, 18:24:31)
[Clang 11.0.3 (clang-1103.0.32.62)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ssl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/Cellar/python@3.8/3.8.3_2/Frameworks/Python.framework/Versions/3.8/lib/python3.8/ssl.py", line 98, in <module>
    import _ssl             # if we can't import it, let the error propagate
ModuleNotFoundError: No module named '_ssl'
>>>

不是在 brew 之外安装 python 包并在 brew 之外安装 aws 命令行，如对此问题的自我回答中所述，这是对我有用的解决方案

• 安装 Xcode 工具：xcode-select --install
• 重新安装python的brew版本：brew reinstall python@3.8

之后

/usr/local/Cellar/python@3.8/3.8.3_2/bin/python3
Python 3.8.3 (default, Jul  8 2020, 14:27:55)
[Clang 11.0.3 (clang-1103.0.32.62)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ssl
>>>

aws --version
aws-cli/2.0.30 Python/3.8.3 Darwin/19.5.0 botocore/2.0.0dev34

好的 - 所以我在这个网站上找到了一篇文章，其中介绍了 Python 的卸载过程以及如何恢复原状，从 here 开始工作。

我使用的关键部分：

brew uninstall --ignore-dependencies python
rm -rf $(pyenv root)
brew uninstall pyenv-virtualenv
brew uninstall pyen

然后用 Python 设置 MacOs Catalina，我关注了this 文章。主要观点：

pyenv install 3.7.7

qwerty@qwerty-mbp > python -V
Python 3.7.3 

qwerty@qwerty-mbp > pyenv global 3.7.7

qwerty@qwerty-mbp > pyenv version
3.7.7 (set by /Users/qwerty/.pyenv/version)

qwerty@qwerty-mbp > python -V
Python 3.7.7 

然后我不得不重新安装 AWS CLI：

sudo rm -rf /usr/local/aws && sudo rm /usr/local/bin/aws

qwerty@qwerty-mbp > python --version
Python 3.6.1

cd /tmp/

curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli-bundle.zip"

unzip awscli-bundle.zip

sudo /Users/qwerty/.pyenv/shims/python awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws

qwerty@qwerty-mbp > /usr/local/bin/aws --version
aws-cli/1.18.53 Python/3.7.7 Darwin/19.4.0 botocore/1.16.3
