1. 确认已安装好最新版本的Bazel和@rules_python。
2. 在Bazel的WORKSPACE文件中添加以下代码：

load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")

http_archive(
    name = "rules_python",
    urls = [
        "https://github.com/bazelbuild/rules_python/releases/download/0.2.2/rules_python-0.2.2.tar.gz",
    ],
    sha256 = "a08426300c250b0fe855d67851620455a2b057cffd8aa03222d87ddbcbfb47b3",
)

load("@rules_python//python:repositories.bzl", "rules_python_dependencies")
rules_python_dependencies()

3. 修改BUILD文件，将PyConfig()改为rules_python.PyConfig()。例如：

load("@rules_python//python:defs.bzl", "py_library")

py_library(
    name = "my_library",
    srcs = ["my_library.py"],
    deps = [
        "//my/dependency",
    ],
    data = glob(["*.txt"]),
    **rules_python.PyConfig().create(enable_local_modules = True),
)

4. 运行Bazel build命令，再次确认是否出现报错。
