Python3.x Python 3.9.8 使用 Black 并导入 `typed_ast.ast3` 失败

由于更新到python@3.9.8，我们在CI管道中使用Black时出错.

black....................................................................Failed
- hook id: black

Traceback (most recent call last):
  File "../.cache/pre-commit/repol9drvp84/py_env-python3/bin/black", line 5, in <module>

  File "../.cache/pre-commit/repol9drvp84/py_env-python3/lib/python3.9/site-packages/typed_ast/ast3.py", line 40, in <module>
    from typed_ast import _ast3
ImportError: ../.cache/pre-commit/repol9drvp84/py_env-python3/lib/python3.9/site-packages/typed_ast/_ast3.cpython-39-x86_64-linux-gnu.so: undefined symbol: _PyUnicode_DecodeUnicodeEscape

可以通过以下方式轻松重现错误:

% pip install typed_ast
% python3 -c 'from typed_ast import ast3'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: 
/usr/lib/python3/dist-packages/typed_ast/_ast3.cpython-39-x86_64-linux-gnu.so: 
undefined symbol: _PyUnicode_DecodeUnicodeEscape

目前唯一的解决办法是降级到python@3.9.7.

还有其他修复方法吗？
