迁移测试文件后Bazel构建Python项目遇pydantic导入错误求助

我正在将大型项目迁移至Bazel，先从项目中基于pydantic的小型封装模块pydantic_utils入手。初始目录结构下添加BUILD.bazel文件后测试运行正常，但将test_some_module.py移至根目录、调整BUILD文件中py_library和py_test的srcs配置后，出现错误：pydantic无法导入TYPE_CHECKING，报错信息显示在导入re时触发ImportError，请求帮助诊断。

初始目录结构 #

pydantic_utils
  +- __init__.py
  +- some_module.py
  +- some_other_module.py
  +- subdir
     +- one.py
  +- tests
     +- __init__.py
     +- test_some_module.py

修改后的BUILD.bazel内容 #

load("@rules_python//python:defs.bzl", "py_library", "py_test")
load("@my_pip_install//:requirements.bzl", "requirement")

py_library(
    name = "pydantic_utils",
    srcs = glob(
        ["*.py"],
        exclude = ["test_*.py"],
    ),
    visibility = ["//visibility:public"],
    deps = [
        "//pydantic_utils/subdir",
        requirement("pydantic"),
    ],
)

py_test(
    name = "test_pydantic_utils_dp",
    srcs = glob([
        "test_*.py",
    ]),
    main = "test_some_module.py",
    deps = [
        "//pydantic_utils",
        requirement("pytest"),
    ],
)

报错信息 #
