从备份安装后，OSX上的“未找到符号：\动态\共享\缓存\包含\路径”？

Question

我刚买了一台运行OSX 10.15.7的新Macbook。我从旧机器的时间机器备份中安装了它

现在，当我尝试导入Python中的ctypes库时：

python -c "import ctypes"

我看到：

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/Cellar/python@3.9/3.9.1_2/Frameworks/Python.framework/Versions/3.9/lib/python3.9/ctypes/__init__.py", line 8, in <module>

我不知道如何调试这个-有人能提供建议吗？这意味着我不能运行Jupyter笔记本电脑，以及其他东西
