fat 文件，但缺少兼容架构有“i386，x86_64”，需要“arm64e”错误与 Mac M1 Pro 芯片上的 bcrypt

Question

我最近使用 M1 Pro 芯片从 2017 MBP 升级到 2021 MBP。

从那时起，我在运行 Python 2.7 脚本时遇到了问题。

我正在使用paramiko ：

#!/usr/bin/env python

...
import paramiko
...

...当我运行脚本时出现以下错误：

Traceback (most recent call last):
  File "/Users/crmpicco/deploy.py", line 14, in <module>
    import paramiko
  File "/Library/Python/2.7/site-packages/paramiko/__init__.py", line 22, in <module>
    from paramiko.transport import SecurityOptions, Transport
  File "/Library/Python/2.7/site-packages/paramiko/transport.py", line 90, in <module>
    from paramiko.ed25519key import Ed25519Key
  File "/Library/Python/2.7/site-packages/paramiko/ed25519key.py", line 17, in <module>
    import bcrypt
  File "/Library/Python/2.7/site-packages/bcrypt/__init__.py", line 25, in <module>
    from bcrypt import _bcrypt
ImportError: dlopen(/Library/Python/2.7/site-packages/bcrypt/_bcrypt.so, 0x0002): tried: '/Library/Python/2.7/site-packages/bcrypt/_bcrypt.so' (fat file, but missing compatible architecture (have 'i386,x86_64', need 'arm64e')), '/usr/lib/_bcrypt.so' (no such file)

正如错误所说，该文件肯定存在，但我不确定如何继续。

locate bcrypt.so
/Library/Python/2.7/site-packages/bcrypt/_bcrypt.so

Answer 1

我能找到的唯一解决方案是卸载并重新安装一堆 Python 包，名称为 bcrypt、cffi、PyNaCl 和密码学。

sudo python2.7 -m pip uninstall bcrypt 
python2.7 -m pip install bcrypt --user

sudo python2.7 -m pip uninstall cffi
python2.7 -m pip install cffi --user

sudo python2.7 -m pip uninstall PyNaCl
python2.7 -m pip install PyNaCl==1.4.0 --user

sudo -H python2.7 -m pip uninstall cryptography
python2.7 -m pip install cryptography --user
